FR:Sources de données potentielles
|Aide||Questions fréquentes||Boutique(en)||Dons(en)||La carte||Traces GPX||Blogue||±|
Ce qui suit est une liste de sources de données potentielles. Certaines sont déjà utilisées, ou ont été importées en entier. D'autres sont en cours d'étude et d'autres ont été rejetées (les détails de leur rejet sont aussi ici). Il existe globalement deux critères:
Avec ces critères pris en compte, nous étudions les sources suivantes, vérifiant si il existe des restrictions d'usage et si elles sont utiles pour nous ou si nous pouvons collaborer, et envoyons par email les résultats aux Mailing lists . Freegis.org assemble une liste similaire , mais elle est incomplète.
Lister les sources de données ici n'est que la première étape d'un processus d'étude et de préparation pour les imports. Si vous êtes intéressé dans la réalisation d'imports soyez très prudent:

Beaucoup de compagnies de transports (taxi, livreur, service de distribution du courrier...) utilisent les données GPS dans leurs véhicules pour faire leur circuit en temps réel dans leurs différents centres ou juste pour leur enregistrement. Il se peut dans leur intérêt de faire de leurs données GPS des circuits dans l'ordre d'améliorer la carte dans leurs aires d'opération. Les taxis peuvent effectivement couvrir rapidement une ville, pendant que les camions sont probablement meilleurs pour les longues distances. Déjà utilisé par Ecourier par le bief de circuit.

La base de donnée mondiale de banque CIA
La base de donnée mondiale de banque CIA II est une collection de données de cartes mondiales, consiste en une description vectorielle des contours des terres, rivières, et limites admistratives. Elle avait été créé par le gouvernement des États-Unis en 1986. Donc elle doit être entrée dans le domaine publique et depuis, les fichiers n'ont pas changés. Il y a environ 1.8 million de points formés en Europe et en N.A.

Les données sont désordonnées et avec des erreurs d'orthographe et d'anciens noms bizarres entrées. La fiabilité est faible. Nous avons importés les données GNS dans quelques régions, en générale pauvre en données. Elles n'étaient pas systématiquement visibles à un système globale.
Main page: Geonames
C'est le nom d'un serveur "wiki" disponible à geonames.org avec le soutiens de réaliser des données avec une licence libre, comme il utilise une multitude de données de source non libres, et basé sur google map. Et donc, il ne respectait pas la charte du projet OSM

La librairie de la carte
La librairie de la carte est une source du domaine publique, carte de données basiques concernant les limites administratives dans les pays développés. Le format de données disponible est Map Maker DRA, ESRI sous forme de fichiers ou d'informations de carte.
Note: Les aires administratives de la base de données sontt licenciés sous,mais ils ne peuvent pas être utilisés dans OpenStreetMap. 
OpenGeoDB a démarré par un projet Allemand pour placer à l'intérieur de l'Allemagne, étendue à l'Autriche, à la Suisses, au Liechenstein et à la Belgique par momrnts. Les données initiales étaient dérivées du serveur de noms de GEOnetr, mais avait été étendue par codes postaux, population, structures gouvernementales.
Les données sont dans le domaine public et peuvent être utilisés sans limitations.

Base de données du littoral
Il y a plusieurs options disponibles pour fixer la base de données du littoral. Pour les chemins piétons le long des sommets des falaises vous devez croire en vôtre libre arbitre pour toute la base de données - mais pour que les propositions soient possibles, il faut dessiner la masse côtière sur toute sa longueur. Voir Proposed features/Coastline
Prototype Global Shoreline
Our script for importing into the OSM database is "Almien coastlines (PGS)"
GSHHS - Global Self-consistent Hierarchical High-resolution Shoreline
Import script is at Almien coastlines (GSHHS), but is not being used in favour of PGS.
GSHHS is a database of lakes and shorelines of the world, resolution of 200m produced in 1996. Delivered with source, written in C, and the PD database. They are also available as shapefiles. Tends to give more accurate coastlines than VMAP0 outside of the US (for some reason VMAP0 seems more accurate for the US). There are issues with inland water (such as the great lakes) though.
(The above info appears slightly incorrect: according to the README the last update was in 2004. It was generated from the CIA WDBII and the WVS).
World Vector Shoreline
Claims, 1:250,000 scale use, seems pretty accurate at least for the GB and Ireland
EVS Islands (Data Dependent)
Based upon different landsat images, some comparision are made against PGS, and there are also maps traced from Google Earth imagery. He makes very beautiful maps of all the islands of the world. http://evs-islands.blogspot.com
SWBD - Shuttle radar topography mission Water Body Data.
Derived from the SRTM digital elevation model. Newer than the rest, potentially more accurate.
From the README: SRTM data are distributed in two levels: SRTM1 (for the U.S. and its territories and possessions) with data sampled at one arc-second intervals in latitude and longitude, and SRTM3 (for the world) sampled at three arc-seconds. Three arc-second data are generated by three by three averaging of the one arc-second samples.
For reference: one arc-second at the equator is 30metres. For the US this means around 18m accuracy, but for elsewhere it's pretty bad. At the latitude of Brussels it would be about 60metres accuracy. For any latitude l, 1 arc-second of longitude is about 30 metres multiplied by cos(l).
The SWBD data is derived from this and claims one-arc second accuracy worldwide, though only lakes greater than 200m are included.
Converting SRTM into OSM format can be done with Srtm2Osm.
Earth Observing Laboratory NCAR.
EOL provides state-of-the-art atmospheric observing systems and support services to the university-based research community for climate and weather research. Most of it is free(?)
"Use that is inconsistent with UCAR's non-profit status and mission. UCAR is a non-profit, tax-exempt organization and, as such, is subject to specific federal, state, and local laws regarding sources of income, political activities, use of property, and similar matters. As a result, commercial use of this Site or the Materials for non-UCAR purposes is generally prohibited. Requests for exception to this should be directed to firstname.lastname@example.org."

ICEDS European Data Server
The ICEDS server is hosted and run from UCL with the aim of serving high-resolution global and continental data. One of the nicest things about the site is its ease of use - you view an area and then click a button to download the relevent data (SRTM, Geological Maps, Landsat 5 & 7, etc). The site is also an exercise in Open Standards and is fully compliant with the OGC's WMS, WFS standards - meaning that a variety of external data sources (Weather and bathymetry for example) can be overlaid with the click of a button (Why not OSM data?). In common with OSM it is also based on an Open source principle - Map Server on Apache on Linux.
Two things I particularly like about the site:
hostip.info Geolocation data
http://www.hostip.info/ has a geolocation database. Geolocation means mapping from IP address to location. It's a neat trick, although the accuracy is obviously quite variable (try it on the site there) We could try to use this to jump to the user's home town, rather than the default world map, when a visitor enters the openstreetmap.org homepage. Might fun, or it might just be confusing when it gets it wrong.
Ip Global Positioning (Unfree)
http://www.ipgp.net will show a map with the location of an IP address. In some cases it will show the location of Internet Service Provider, but you can still make an idea.
Defense Aeronautical Flight Information File. Published by the US Department of Defense, lists pretty much every airport runway worldwide. Apparently, they're going to be removing the dataset from public domain in October 2006. This is used to populate the scenery databases for Flightgear flight simulator and X-Plane. Whilst the dataset is still being kept updated in the public domain, I'll work out an import to Openstreetmap of the runways and taxiways. Welshie 09:51, 25 Jun 2006 (UTC)
Many Amateur radio operators have GPS receivers connected to packet radio transmitters and transmit their location in a standard format known as APRS (including fixed stations, weather stations, and mobile stations) on standard frequencies from which the data can be picked up and is injected into a internet infrastructure APRS-IS. The infrastructure includes databases APRSWorld, OpenAPRS, and a substantial supporting body of open source software (which would make it simple to set up a database to selectively mine internet feeds for data coming from mobile stations that are likely to be traveling on roads). APRS data does have some intrinsic limitations - positions are usually transmitted on 5-10 minute intervals, and a widely used non-compressed format limits the precision of latitude and longitude to 0.01 minute (see the APRS protocol specification for details). Given the origin of APRS data as Amateur radio transmissions, they are likely to be in the public domain.
The guys who gave us Pledgebank made placeopedia as well, it's a way to use Google maps to geo reference wikipedia articles. The database is held separately from the wikipedia one, and can be accessed with rss, xml and kml feeds from their site.
It says it is available under a Creative Commons license, but not which one.
This has been discussed on the mailing list, and the consensus is that Placeopedia is a derivative work of Google Maps. Although it's very unlikely to be challenged by Google Maps / Teleatlas, it's not suitable for use in OpenStreetMap (http://lists.openstreetmap.org/pipermail/talk/2005-October/001212.html is one of many relevant posts, and a good summary of the argument).
"The Second Administrative Level Boundaries (SALB) dataset is a dataset aiming at improving the availability of information about administrative boundaries down to the second subnational level. The SALB dataset forms part of the UN geographic database and was developed in the context of the United Nations Geographic Information Working Group (UNGIWG)."
True Marble imagery (Unearthed Outdoors)
Full color global imagery, built from the best available Landsat scenes which have been chosen to optimize vegetation quality and to reduce the cloud cover. These orthorectified scenes were fed into proprietary, advanced, color adjustment algorithms to produce true color imagery while reducing atmospheric haze. This imagery was optimized to produce the most natural color while maintaining a high local contrast and dynamic range, resulting in a significant improvement over similar products.
A reduced resolution of the True Marble™, Global True Marble™, is available for free download. This dataset can be used to preview pending purchases, or for any other usage. We only ask that copyright be attributed to Unearthed Outdoors when reproduced.

World Database on Protected Areas (WDPA) (Rejected)
"The World Database on Protected Areas is a foundation dataset for conservation decision making. It contains crucial information from national governments, non-governmental organizations, academic institutions, international biodiversity convention secretariats and many others. It is used for ecological gap analysis, environmental impact analysis and is increasingly used for private sector decision-making...."
Ramsar Wetland Sites
The data included in the database derives from the Ramsar Information Sheet, the Ramsar National Report and/or from Administrative Authority correspondence provided by Contracting Parties. This includes information on wetland types, land uses, threats, hydrological values of the sites etc. The Ramsar Sites Database is primarily a tool to look at Ramsar Sites across geographic and thematic boundaries, useful and necessary for maintaining an overview of a global network of well over 1700 internationally important wetlands from 158 countries.
OpenCellId is the biggest open source data for CellID, and provides an API to both gather data to locate new cells tower, as well as API to locate a user using Cell positionning.
Source code is provided on a GPL license, while data are under a Creative Commons Share Alike license.
Plans are to support Wifi/Bluetooth positinning.

OpenBmap cell and wifi access points (incorporating data from opencellid
openBmap is a free and open map of wireless communicating objects (e.g. cellular antenna, Wi-Fi, Bluetooth). It provides tools to mutualize data, create and access this map.
data is available under creative commons Attribution-Share Alike 3.0 Unported license, and is currently provided as a static download, updated regularly
the site owners intend to create an api, which could allow regular, scripted updates to the data.
alternatively, it could be suggested they adopt their site/software, to upload data direct to osm

CODATA Roads Data Catalog
A catalog of roads data sets, globally, compiled by the gRoads project. There are hundreds of data sets listed here (many probably already investigated), under all sorts of licensing schemes. There are certainly data sets new to the OSM community that are worth investigating.
The interim PDF is posted at Media:CODATA_Roads_Data_Catalog_v1.pdf
There are possible plans to post this database to the web, with query front end.
United Nations Laws Of the Sea
The UN DOALOS have a database over all maritime border claims. There is no apparent license on the data and this is the borders definitions. But the database is a database of different PDF files with coordinates of baselines and territorial borders. The text has to be parsed by hand and other maritime borders needs to be calculated from the baseline (see maritime borders). Data is to be tagged with source=UNCLOS
Though the two projects have significant overlap and are both Creative Commons, they are [ http://wiki.freebase.com/wiki/License_compatibility#Compatible_licenses_for_structured_data incompatible]. Freebase.com is licenced under CC-BY. The biggest hurdle in using OSM data within Freebase has been the OSM share-alike license. All the data in Freebase is available under a CC-BY (attribution only) license, allowing anyone to use the data in any way they want as along as they acknowledge Freebase. The main difference between the licenses is that the Freebase CC-BY license does not impose a share-alike requirement on users of the data.
That said, the OSM community is currently voting on an updated license which could make collaboration between the the two data sets much easier in the future (for more information see: Open_Database_License)
In spite of the licence conflict, simply linking these resources together wouldn't be a problem.
we could connect relations to locations
and connect osm'samenity nodes ( or 'points of interest'). both databases for example, have a mount sinai hospital-
List of Marine Lights
This is a database of lights, radio, and fog signals. It contains almost all lights on the world and is published by the US Nationional Geospatiol Intelligency Agency which may have a useful copyright permisson.
The information is published as PDF documents and we have already parsed them into an OSM appropriate format. The tags used for imported are planned to be the OpenSeaMap proposed seamark:*=* ones.
EC-JRC built-up areas / density of building from Bing
This is partially a follow-up to this thread: http://lists.openstreetmap.org/pipermail/imports/2011-June/000987.html
We (the Joint Research Centre of the European Commission) have developed a set of scripted tools to extract built-up areas, built-up density, and location of human settlements from (very) high resolution satellite imagery. The result is quite reliable and our methodology has been warmly received by the remote sensing community. Part of the methodology is described in this paper: http://ieeexplore.ieee.org/search/srchabstract.jsp?tp=&arnumber=5764726

US Dept. of State, International Boundaries
From the Office of the Geographer and Global Issues (INR/GGI), we are free to use these international boundary lines (attribute = 1), other lines of international separation (disputed lines; attribute = 3) and other lines of separation (attribute = 7.) They reflect US govt. policy and thus not necessarily de facto control.
The most recent edition (September 2012: "LSIB4b") is available at https://hiu.state.gov/data/data.aspx.
An older version ("LSIB3", Sept. 27, 2011) is currently available at http://rockburger.com/openstreetmap/state/ . The lines are generally highly detailed, accurate international boundaries for Asia in one 9 mb zipped file (India's lines with most of Bangl., Burma, Nepal are still in work), and, in an 11 mb file, for the rest of the world, with much of sub-Saharan Africa (and N. Argentina) still in work.
The lines are produced and regularly updated by geographers at State and colleagues from other agencies based on imagery, old treaties/maps, and other sources. For most of Europe and the U.S., the lines are not particularly accurate; accurate data for these areas are widely available via other sources. This "Large Scale International Boundary (LSIB)" line data as well as polygons are also available at http://geocommons.com/search?model=&query=LSIB, though there may be some issues with the processing in GeoCommons.
Nothing in project MAPEAR should be used since their license is not compatible. Although their maps are free as in beer they are not free as in speech.
geoland.at is an effort to bundle GIS data from the Bundesländer (federal states). They state  that usage of grapics/informations within the scope of publications / websites is only permitted provided that the "© Geoland" and the source reference www.geoland.at are given.
geoimage.at provides a free WMS for whole Austria since October 2010 in 1m resolution (for the time being, they will provide it for the duration of 2 years). Details of the legal situation are still to be worked out, but employees of geoimage.at said, that they definitely are willing to cooperate with openstreetmap. Please note, that the WMS is in a special Lambert-projection and (until now) cannot be directly used in any editor without having changed some settings. See WikiProject_Austria/geoimage.at for details.
The local government of Styria provides GIS data on their website . According to the website the data available for download is freely usable "frei verwendbar" (free as in speech) provided their copyright notice "Quelle: GIS-Steiermark" (which would translate to: "Source: GIS-Styria") is preserved. The data covers roads, rivers, cities and political territories. It is available in EsriShape format. Maybe the government of Styria would be willing to relicence their data under CC terms.

Has ARC/INFO, MapInfo, and GML road network data with street names and address ranges (like TIGER/Line data, who they say they are cooperating with). Their license agreement is similar to GeoBase's (they state that their data will become part of GeoBase by the 2011 census), however the data seems to be a bit off from the GeoBase set.

The national LocationCodeLists of the TMC (Traffic Message System = traffic-jam warning via radio) -system contain a highly simplified road-network of all the major roads and many important points in the country. The location-codes themself are also highly usefull to have in OSM for Routing -software that can receive TMC-messages and thus avoid traffic jams and other obstructions.
These lists are sometimes free to use, sometimes closed but due to the fact that they are widely distributed with all commercial navigation-systems, there may be little resistance in getting a permission to tag existing OSM-objects with their location-code or use the list to check for missing ways in our map.

Via Alpina dataset on accommodation in the Alps
638 accommodation places, many attributes. Dataset in 5 languages. Example: http://www.via-alpina.org/point/1598
The origin (licence) and accuracy of the location is uncertain, so better to use the attributes only. Part of the data is already outdated, so it is advised to check first (maybe by calling). In Italy at least, the '0' (zero) after +39 is missing in the online phone numbers (but GSM lines do not have zeroes).
(Do not hesitate to contact me or the Via Alpina international secretary for more details Mayeul 18:03, 31 May 2012 (BST))
The National Land Survey of Finland (NLS) has recently (1 May 2012) opened some of its dataset under an attribution only -licence. The amount of data available is enormous, and the local community is discussing the details.
The Finnish Road Administration (Tiehallinto) maintains a database called digiroad covering all roads and streets in Finland which would contain all information OpenStreetMap needs about roads for Finland. (Shorelines, parks, amenities, boundaries, placenames, etc would still have to be collected using traditional OSM procedures.) The database is available for licensing relatively cheap, a few hundred euro. Unfortunately, as far as I can see, it is not currently licensed under terms suitable for OpenStreetMap. The English summary document says that "Data from Digiroad will be free-of-charge for public organisations for internal use and for free public services" but I couldn't find anything as promising in the more recent Finnish documentation.
However, my (naïve?) hope is that it will eventually be possible to convince them to "open up" the data enough for OpenStreetMap. Clearly digiroad is not maintained and sold for profit, there aren't even any royalty fees collected from commercial users of the data.
I mailed the project coordinator asking for more information. The coordinator had changed from that mentioned on their webpage to another person though, though, but I did eventually get a reply from her. Basically it was quite positive, but they need time to consider this. They also interpret current regulations as allowing them to sell (for the very reasonable amount) the material only to companies and institutions, not to individuals. Also the data should be used to benefit "services for transport and logistics" (badly translated from the vague term "liikkumisen palvelut"), but on the other hand, what else could it be used for? (Maybe the intent of this restriction is to prevent production of pure maps from the data. That would then indeed seriously prevent importing it into OSM, I think.)
I sent more mail asking for clarifications, pointing out that the price as such is not the issue here, surely it would be possible to collect for instance 20 euros per person from a group of interested individuals, or even ask some company to "sponsor" freeing this data. The licensing issues are the main concern. No further replies yet.
I hacked together some code to convert the sample data available from the website  (sorry, documentation in Finnish and Swedish only) into OSM format. See here: . Plain C. Needs shapelib and iconv(), otherwise no external dependencies. Screenshot of part of sample data loaded into JOSM here: .

The Finnish page says that the licensing conditions are formed to match client requirements so it should be possible to get a good license. Then the only problem would be their fee (about €380) which mandated by law. --LH 15:11, 9 September 2007 (BST)
Reading the contract details, the licence gives you the right to use the data for a certain purpose for a maximum of 5 years. After the 5 year period the copy must be returned or destroyed. I recommend reading the example contract.
The Finnish Rail Administration possibly has exact geodata for all of the state-owned rail network. With rail deregulation being implemented and all, they seem to be quite open, and publish lots of information on the web, including a very detailled "Network Statement". Alas, this document doesn't include coordinates of stations etc, only the distance (down to one metre resolution) along the rails from the designated point of origin. (Trivia: this point of origin is the previous Helsinki station, 159m south of the present Helsinki Central station, and not actually accessible by rail.) I mailed then asking if the network geodata (and useful other information, like number of tracks and electrification) could be made available in some suitable format and could be donated to OSM. They didn't promise anything except that maybe in the next "Network Statement" they will include actual coordinates. So probably it doesn't make sense to wait for something that might not happen, but continue mapping rail lines as before.
They have an interactive web service that contains information for all level crossings in Finland. For many of the crossings coordinates are included (in the Finnish national KKJ grid, not WGS84, but conversion formulae are well-known) . From this service one could semi-mechanically generate an at least partially quite accurate (for those lines that have plenty of level crossings) map of the rail network. This might be interesting especially for freight-only lines where actual GPS mapping of course is hard to do (without actually trekking along the line). Data for one level crossing here: . Their reply to my mail was a bit vague but I got the impression that it should be OK to import the level crossing locations. The location of an individual crossing is obviously not a copyrightable work, but as a collection it is covered by copyright for databases and collections.

Portale Cartografico Nazionale
For the whole of Italy there is a WMS server. In 2010 use of 2 WMS-layers for OSM was explicitly permitted (orthographic photos from 2006 for the whole of Italy and from 2008 covering only the regions Lazio and Umbria) (see authorization letter from the PCN). The rest of the information on the PCN is not free to use for OSM as of May 2010. For more information and instructions how to use the aerial imagery, please visit WikiProject_Italy/PCN in Italian language. These photos offer (almost) complete coverage and are much better aligned than Bing aerial, but Bing has higher resolution and is more up to date so if you want to use aerial imagery for mapping in Italy you should probably use both sources.
A list of Italian postal codes is provided by the Free Software Foundation Europe. It includes the list of street-names for major cities.
Regione Autonoma Friuli-Venezia-Giulia
All of the data created and maintained by the Regional Administration
Regione Lombardia has its own wiki page
The Regione Piemonte has put data from their stock online at  These include a detailed DEM and the CTRN for the whole of Piemonte down to 1:10000 resolution. Some of the data are quite old, but potentially still extremely useful (e.g. for streams, toponyms). The data are under various CC licenses. No permission to use the data in OSM has yet been requested or given.

OpenStreetMap data directly generated from the orthophotos must show "国土画像情報（オルソ化空中写真）国土交通省" in the data browser of www.openstreetmap.org. The source tag is useful for it. Then, for the second derivative works, which means works derived form OpenStreetMap data, must show "(C) OpenStreetMap" and make a web link to http://www.openstreetmap.org/ .

Informasjon om bussholdeplasser o.l.
Det er flere selskaper som driver med kollektivtransport som samtidig har databaser over posisjoner på busstopp, båtanløp o.l. for reiseplanlgegging. Eksempler:
I prinsippet burde slik informasjon være offentlig. Vi burde dermed ha all mulighet til å innhente tillatelse til å benytte deres informasjon i følge lisensen til OSM. Det kan hende at det er tredjepart (kartselskap) som har hentet inn de nøyaktige posisjonene, men det er vel gjort på oppdrag av det offentlige og da er det vel oppdragsgiveren som "eier" dataene og kan lisensiere dem til annet bruk.
kolumbus.no (Rogaland kollektivtrafikk)
Har ruteplanlegger med alle holdeplasser i Rogaland (pluss noen i Hordaland og Vest-Agder) I tillegg har de posisjonene til mange bedrifter i Rogaland, men disse er vel kjøpt av tredjepart og er vel vanskeligere å få lov til å bruke. Alle holdeplasser har et åttesifret nummer(kkkknnnn der kkkk er kommune (1103=Stavanger) og nnnn er holdeplassnummer). Hver holdeplass har et navn, enten oppkalt etter nærliggende landemerker eller eller gater som krysser traseen. Holdeplasser på hver side av gaten har forskjellig ID, men gjerne samme navn. Basert på ID kan det linkes til kolumbus.nos sider som viser avganger fra stedet. Dersom vi får lov til å bruke det vil jeg legge inn busstoppene listen med operator=kolumbus.no, ref=kkkknnnn
Holder på å forfatte en mail til Karianne Haarr Nedrebø, (kommunikasjonssjef, Telefon: 51 51 65 45 / 916 70 437, email@example.com) om bruk. Gorm 14:24, 20 April 2009 (UTC)
Hele postadresseboken. Langt de fleste gatene i større byer. Hva kan vi bruke dette til? Ser ingen informasjon om hva dataene kan brukes til, men er vel som vanlig best å spørre.

I følge digi.no, har NRK fått en liste over mobil-basestasjoner i Norge, og plottet disse på google maps. Jeg har sendt en mail til Espen Andersen i NRK hvor jeg spør om OSM får bruke disse dataene. Selv om det er uklart hvordan dette skal tagges (man_made=tower?), kan slike data være nyttig for lokalisering, f.eks. om basestasjon-id kan knyttes til koordinater. --Kristoffer.koch 15:43, 3 February 2010 (UTC)

One branch of the local goverment has a GIS-like application for controlling the rural land use, with a lot of excellent ortophotos: http://sigpac.mapa.es/fega/visor/ (Flash required) This branch has been contacted, and they have said (quite literally):
People from Madrid have already contacted the IGN ("Instituto Geográfico Nacional" or "National Geographic Institute"). They want to make data "more public", and so have agreed to let us import some of their data. Depending on the success and impact, we might be able to import lots of data and use the new aerial imaginery (called "PNOA", covering the entire country at 50 cm/px).
Spanish Cadastre is publishing all cadastrial data as a WMS service . They say:
* as in "free beer"
** as in "freedom"
According to the above statement, data from Spanish Cadastre can be imported into OSM once it has been transformed, for example from the original shapefiles->reproyected to EPSG:4326->converted to *.osm format.
Spanish Cadastre has a lot of information with very high accuracy, such as buildings (shape, use, height, number of floors, etc.), land use, most of streets and roads of the country, power station, trees... Many of this information is currently in OSM, mainly ways and roads, but a great part is missing, specially in low populated areas where a ground survey is less likely to be made. More information about this topic can be found in Catastro España. A long discussion has been held on Spanish mailing list, with general agreement on the usefulness of importing these data.
The IGN publishes a lot of (free as in "free beer") imaginery at

Tajikistan is at the same time one of the most poorly mapped countries on OSM and a very prone-to-disasters country, thus the need to find good data sources and to improve the quality of the map. A dedicated Wiki-page page has been setup.
So far, I haven't found any national dataset that is for sure 100% free of copyrights. Some potential sources are listed below, with mention of the potential problem. Please feel free to contribute to this list:
I wrote an email to my local authority when I found out that they notify interested parties on the council's decisions on naming and numbering new properties and streets. For areas that have already been densely surveyed and mapped (90%+), it would be an invaluable list of places that might need re-surveying or other editing.
I got an answer back - the council do make the information freely available on their web site, but it's in the form of a PDF file per decision, in a human readable format only, and the whole list is not easily searchable. The information contains no geographic information other than relative references, eg.
That a new development of a house being built on the site adjacent to 47 Belmont Avenue, Barnet, Herts, EN4 shall be postally addressed: WOODVIEW HOUSE, 1A NORRYS ROAD, BARNET, HERTS, EN4 9JX.
Occasionally, whole new streets get notified.
That the access road beginning at the junction with Page Street, London, NW7 serving Copthall Leisure Centre and the surrounding properties shall be named: CHAMPIONS WAY, LONDON, NW4/NW7. That the access road that starts at Champions Way and ends at the Great North Way, London, NW4 serving Copthall Stadium shall be named: GREENLANDS LANE, LONDON, NW4.
These lists are not in a standard format among local authorities, and each local authority needs to be handled differently. I plan on writing a web scraping script to attempt to identify the changes, and by searching the nearby street names, pinpoint them on the map, so I would have a list of streets that need editing / surveying.

Roads database Contains information like
Also they offer a way to search for local facilities - http://www.fife.gov.uk/yourtown/index.cfm by postcode. This data could easily be extracted automatically, but the licences mentioned on the website are unsuitable (it's also unclear that this data is covered) and derivation from OS issues are also unclear.
I have not contacted them.
The National Public Transport Access Nodes (NaPTAN) dataset contains details of some 350,000 public transport access points in Great Britain including bus stops, railway stations, tram stops and ferry terminals. See NaPTAN for more details.
Natural England have datasets containing boundaries of Open Access Land (Crow Act 2000), National Parks, SSSIs, National Nature Reserves, Marine Conservation Zones, and many other protected areas. It also has data on National Trails. On April 1st 2012 Natural England started releasing data under the Open Government Licence (OGL) therefore making it available for mapping in OpenStreetMap.

The Food Standards Agency produces machine readable versions of the Food Hygiene Rating System data. This ranks restaurants and businesses that sell or serve food or drink with a rating from 1 to 5. See Food Hygiene Rating System for details.
The government recently approved a law making all government data (except the one that has privacy or security issues) public and free of copyright. In particular GIS data from the municipality of Montevideo is now available from its site.
Check metadata for each shape file obtained from government sources, and search for "Use_Constraints:" or similar to help determine usability of data with OpenStreetMap. Many will list this as "None" and should be fine to use, but others from the same page will have varying constraints. When there is any doubt, ask the contact listed in the metadata for permision, and check with the Legal Talk mailing list. --Dalep 04:36, 2 September 2008 (UTC)
More detail on the TIGER page
The Tiger road data is imported
The U.S. Census Bureau's TIGER geographic database covers the United States (including Puerto Rico). The data is available from the Census Bureau as TIGER/Line files in ASCII text format - http://www.census.gov/geo/www/tiger/. ESRI shapefiles of the TIGER data is available at http://www.esri.com/data/download/census2000_tigerline/index.html .
The TIGER data are in the public domain - http://www.census.gov/cgi-bin/geo/tigerfaq?Q11 .
The Many national forests have GIS data available for download. A statement from region 6 (Pacific NW) http://www.fs.fed.us/r6/data-library/gis/disclaimers.shtml says that the data are public domain. Unfortunately each forest seems have their own index of data and data organization. There are some files very relevant to OSM (trails; recreation points listing campsites, docks etc) and some not so useful to the normal OSM reader (owl and fish habitats).
The National Park Service has a data clearinghouse often with trails (some historic paths) rivers, roads and often with very high resolution orthophotos.
The USGS has a centralized database ( http://seamless.usgs.gov ) that contains many data sets, several that would be of use to OSM, including very detailed surface water data sets (rivers, streams, lakes, tiny ponds), dams, federal lands . The data are in the public domain ( http://seamless.usgs.gov/faq/general_faq.php#six ). However, they do request attribution of data to USGS, so it may require a followup to use in OSM.
National Hydrography Dataset
Part of the USGS Data, the National Hydrography Dataset contains detailed information on nearly all waterways and bodies in the United States
The GAP Analysis Program
Also a project of the USGS, the The GAP Analysis Program was conducted state by state initially and most recently on a regional basis. Relevant data includes landuse/landcover and stewardship/conservation lands, which includes military and DOD lands, and state/federal/local lands preserved for conservation purposes.
DOT homepage links for all 50 states. Check each for the GIS department, and statewide downloadable data.
FAA Digital Obstacle File (DOF)
The FAA Digital Obstacle File contains coordinates and elevations, as well as some meta data for aviation obstacles in the united states. It is distributed from the DAICD. I believe that the data is public domain but the CD is sold as a subscription; someone like myself who has the CD could theoretically import the data into OSM without violating copyright. (TODO: double-check IP status.)
The DOF would be a useful way to populate the map with aviation-chart-related items, particularly ones that can also serve as landmarks: smoke stacks, antennas, etc.

Next Generation Radar (NEXRAD) Locations
This geospatial rendering of weather radar sites gives access to an historical archive of Terminal Doppler Weather Radar data and is used primarily for research purposes. The archived data includes base data and derived products of the National Weather Service (NWS) Weather Surveillance Radar 88 Doppler (WSR-88D) next generation (NEXRAD) weather radar. Weather radar detects the three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. From these quantities, computer processing generates numerous meteorological analysis products for forecasts, archiving and dissemination. There are 159 operational NEXRAD radar systems deployed throughout the United States and at selected overseas locations. At the Radar Operations Center (ROC) in Norman OK, personnel from the NWS, Air Force, Navy, and FAA use this distributed weather radar system to collect the data needed to warn of impending severe weather and possible flash floods; support air traffic safety and assist in the management of air traffic flow control; facilitate resource protection at military bases; and optimize the management of water, agriculture, forest, and snow removal. This data set is jointly owned by the National Oceanic and Atmospheric Administration, Federal Aviation Administration, and Department of Defense

The entire state is covered, with most counties photographed as recently as 2008, but check their coverage map to find out for specific counties. Unfortunately, the common OSM editing tools don't support MrSID, but with some effort, the files can be converted and served through a standard WMS.

An e-mail from David Giordano at ncmail.net (listed contact) confirms this. The data is broadly broken down into two categories: vector data and raster (imagery) data. A WMS service has been purportedly set up.
Central Ohio Transit Authority has public data for the following (bus routes, stops, park and rides, ammenities) available in shapefile format. Requests can be made at 
OGRIP (Ohio Geographically Referenced Information Program) provides public data for road centerlines, aerial imagery, LIDAR, and much more. Mostly avaiable in shapefile format. The main website  links to all of the data
Ohio Metadata Explorer provides lots of public gis layers from different state and local departments. 
See import page
State of Oregon Geospatial Enterprise Office has well over 100 datasets to choose from, all in the public domain. Some of the data is very recent (from within the last year), and some of it is quite historic. Beware that Oregon GEO is using Oregon Lambert Projection.
portlandmaps.com is operated by the city of Portland and has GIS datasets. A phone call to the City indicates the information on the site is public domain. Also, it seems the raw GIS data might be available through Metro.
Mt. Hood National Forest, Oregon
Jaimie L. Bradbury ( firstname.lastname@example.org ) has GIS datasets of the MT. Hood National Forest in Oregon, US that are in the public domain in the US available. Again, I don't have the necessary technical expertise to actually do any import work, so maybe someone else could pick this up, or help me do it myself. The rest of the national forests in the US probably have public domain data like this that includes trails and such. I'd be willing to look into this more if it would be useful. --anlayne 18:54 27 June 2008 (UTC)
Allegheny County, Pa
Allegheny County has very nice, accurate GIS data available in both shapefiles and as WMS layers at PASDA. These are much more accurate then the TIGER lines, and include bike paths and pedestrian-only ways.
I've spoken to them on the phone (on 7-8-2008), and they consider this data to be in the Public Domain. I'm trying to figure out how to upload this data to OSM - if anyone had tips, I'd love to have them. --Morgan-pgh 16:39, 10 July 2008 (UTC)
GIS data is also abundant for Philly at PASDA. (click "Download Data" and search for keyword "Philadelphia".) Useful shapefiles include bike network, building footprints, parks, schools, fire stations, and railroads. Presumably the shapefiles that originate from the City of Philadelphia are in the public domain as it is a government entity.
State GIS portal but no direct downloads.
Texas provides some good data from the Texas Natural Resources Information System (TNRIS) .
The City of Austin has an excellent set of public-domain GIS data available for download as shapelfiles covering the city and its environs. Not only are there up-to-date layers for streets and arterials, but also water features, railroads, political boundaries, etc. There also is a comprehensive file of property parcels, and another file of points for discrete addresses. 
Utah GIS portal "The State Geographic Information Database (SGID) contains files and links to several different categories of data sets. Data presented for download on this site is considered to be in the public domain."
Some data sets have required disclaimers and attribution for printed and direct use.

Town of Blacksburg
Washington Department of Archaeology and Historic Preservation (Much of the DAHP data is not available due to looting issues, however historic places may be possible to obtain)
University of Washington Geospatial Clearinghouse (The Washington Geospatial clearinghouse contains data from many different sources with different licenses)
Clallam County, WA
Clark County, WA
The city of Spokane, WA publishes free (gratis) GIS datasets for street centerlines, parks, waterways, city boundaries, etc. The centerlines seem to cover all of Spokane County.
Their data is of much better quality than the TIGER/Line data—though TIGER/Line does cover a few things that Spokane's data does not: roads in some trailer park in the Latah area (Club Dr., etc. around 47.63783,-117.44589); Centennial Trail (partial coverage).
I'm contacting them to see if we can include this in OSM. --Jpl 01:29, 15 March 2008 (UTC)
