Que doit-on cartographier ?

Regardez FR:WikiProject_Haiti/Tasks_and_Ideas#Mapping Tasks.

Comment cartographier ?

Si vous êtes un nouveau contributeur OpenStreetMap, allez consulter les instructions et les tutoriels ici.

• Adding street names for streets that have already been traced
  • See how to use JOSM to complete strate names based on data in the USGS maps
• Tracing from post earthquake imagery (See Imagery and data sources)

• Older maps from Perry Castaneda Library Haiti (many outside PaP)
• Older maps from New York Public Library (many outside of PaP)

Please upload frequently to avoid conflicts! When using JOSM, please also update data frequently to avoid conflicts!

Collecte des données

• Collection and freeing of other data sources (vector and raster), for names, features. And for imagery outside Port-au-Prince
• Connect with individuals familiar with Haiti geography
• Help warping map images on a special instance of Tim Waters's map warper dedicated for this purpose. Once a map is warped, a WMS link can be copied from the "Export" tab of the warper to use as a basemap in JOSM.

Rapports de diff

• Rapports de diff (mesures de l'activité des contributeurs) par ordre chronologique :

• Haiti0.png Haiti1.png Haiti2.png Haiti3.png Haiti4.png
• porto0.png porto1.png porto2.png porto3.png porto4.png

(mis à jour fréquemment et à la demande à Gary68)

OpenStreetBugs

OpenStreetBugs can be used to:

• report possible errors in OSM data
• request verification of features (e.g. building collapse, refugee presence)
• request completion of features (e.g. waterway extension)

Rapports d'erreur

There is a big list of different error reports from gary68 tools on this page. Will be updated a few times a day.

• now a gpx-file with the error-reports can download for the direct import in the osm-editors. thanks to FlaBot. --Jan Tappenbeck 23:34, 26 January 2010 (UTC)

Bonnes pratiques

• Mapping individual buildings

• Don't map individual buildings unless you have access to hi-res imagery, i.e. Googles aerial imagery
• Don't map individual buildings unless they are large and free standing (and unless you have access to fairly precise imagery)
• In areas with densely packaged small buildings do map an area tagged with landuse=residential

Don't map individual buildings in these areas. Use an area tagged with landuse=residential

• Trees

• Don't map individual trees unless you have access to hi-res imagery, i.e. Googles aerial imagery

Don't map individual trees in residential areas like this one

• Tagging highways

• Don't tag with highway=living_street if you trace from satellite or aerial imagery. In urban areas like Port-au-Prince or Jacmel, highway=residential is usually appropriate.

Bonnes pratiques suggérées

for consideration - rewording - acceptance or rejection

• When looking at an area new to you, make sure to move the imagery to best match the existing mapped information rather than diving into moving mapped elements to match the imagery.

• I think that well aligned imagery is now available: Googles imagery, WorldBank imagery, NOAA imagery. I feel that best practice should be to actually allign mapped elements with hi-res imagery from Google, WorldBank and NOAA, and to follow your principle in all other cases. Gubaer 17:38, 30 January 2010 (UTC)
  • I agree with you ... the trouble I have is in distinguishing well aligned from poorly aligned imagery. It would be useful to have that kind of meta-data available when you are picking an image set to use. The whole process of preparing an image set for general use is pretty much a black box for the majority of mappers, I think. Thanks for considering this. --Ceyockey 18:30, 30 January 2010 (UTC)

• When in doubt about whether to use highway=residential or another highway value, use highway=unclassified. Avoid using highway=road.

Demandes des équipes sur place

Responders on the ground are making requests for specific thematic and geographic data sets. Please specify time, who, and where the request was made. If possible, please communicate with them if the request has been filled. Think of this a lightweight ticketing system.

• "Street names in PaP are critical, streets around the airport and around Delmas and Carrefour Feuilles are critical. So are streets in Carrefour. POIs are not so critical have most of the essential ones already and we are mostly getting street addresses which can be found if we have the streets. Would also be nice to know whether block numbers are increasing or decreasing on streets.", Ushahidi, Anna H Schulz <Anna.Schulz@tufts.edu>, via CrisisMappers, 20100118

Lieux

Cities outside Port-au-Prince. Especially important in the weeks ahead, as the response expands outside the capital

Potlatch links below can be used as bounding-box URLs in JOSM; the Town/City node links provide access to place meta-data and an alternative starting point for navigation

• Cap-Haïtien: Potlatch | City node

  I've added the '93 CIA map data, please bring it up to date - AndyGates.

  Still very much to do! Check http://www.openstreetmap.org/?way=48431814

  Street names added from MINUSTA city map according to this diff.

  Street names and POI from MINUSTAH added; detail-mapped from NOAA 18 Jan aero imagery.

Pays en entier

Haiti, bbox=[-74.76,17.78,-71.43,20.26]

OSM |working on

The bbox shown covers all of Haiti including territorial waters. This can be used as a "bbox predicate" in Xapi queries to retrieve a .osm file for a single tag value (an Xapi limitation), such as amenity=hospital; the url for this query would be http://xapi.openstreetmap.org/api/0.6/*[bbox=-74.76,17.78,-71.43,20.26][amenity=hospital]. See the Xapi article for more information.

• Even look at these Map.

Frontières et limites administratives

Haiti is organized into 10 Departments which are further divided into 41 Arrondissements and 133 Communes (from Wikipedia). Communes are further divided into sections. For the Haiti Earthquake mapping pcodes have been associated with various relations; pcode:1 for Departments, pcode:2 for Communes and pcode:3 for Sections.

For a list of OSM Relations for the boundaries that have so far been imported/created see WikiProject_Haiti/Status/Boundaries

Administrative boundaries and invalid relations created with Gary68's script boundaries.pl [2][3].
http://yellowcabcar.de/osm_haiti/boundaries.html

An admin boundaries shapefile can be downmoaded at http://labs.geofabrik.de/haiti/boundary-shapefile/ It countains proper polygons for all boundary=administrative objects (whether closed ways or closed multipolygons), including the national borders of Haiti and the Dominican Republic. The shape file does not contain such administrative areas that have an invalid geometry in the current OSM data set. This shapefile is not updated automatically. If needed ask to

Liste des tags

• Humanitarian_OSM_Tags has a discussion of tags and current assessment of tags - please contribute.
• Tagstats dedicated to the Haïti extract has been set up. It helps us assessment what is actually used, what harmonization might be needed to make the data more practical for the end users. Updated every 15 minutes.

Tags spécifiques

• Bridges using bridge=collapsed for damaged bridges. Particularly wanted 17:00 GMT 2010-01-14. (Gene Longenecker, pressumably Region IV co-ordinator for NEHRP/FEMA stated a need for a 'bridge shape file layer'). These are now provided in the roads layer thanks to Geofabrik, but need mapping.
• Spontaneous camps using tourism=camp_site and refugee=yes. GIS practitioners at the United Nations Office of Coordination of Humanitarian Affairs (UNOCHA) mentioned the following mapping requirement: "NEED to map any spontaneous camps appearing in the imagery with size in area". The given tags tags would fully specify this, and be rendered immediately
• Buildings using building=collapsed or earthquake:damage=collapsed_building primarily, though other tags are used -- see Humanitarian_OSM_Tags.
  • EU JRC/Ithace and UNOSAT are producing damage assessment maps.
  • added a bunch of damaged points derived by Ithaca by photo interpretaion:
  • Tag used:
    • earthquake:damage=collapsed_building
    • earthquake:damage=spontaneous_camp
    • earthquake:damage=damaged_infrastructure
    • earthquake:damage=landslide

zvenzzon made a map that shows tag usage for the tags above: http://zvenzzon.mine.nu:81/map.html

earthquake:damage=spontaneous_camp should soon appear in osmarender too

http://haiti.openstreetmap.nl is a minutely updating Mapnik render that shows is too.

• Road blockage
  • barrier=obstacle for small obstacles on the highway which may be visible in GeoEye imagery.
  • impassable=yes for a stretch of road which is impassable due to multiple obstacles or a debris field.

Traduction

The primary language of Haiti is French; additionally, there is much discussion of Haitian Creole, with potential tagging as name:ht=* for Haitian Creole names. Sources may cite names of facilities, infrastructure in French. A glossary of French topographical terms may be found here.

Note that name=* stands for "the default name, used locally". Multilingual support may be of value, this can be achieved through multiple use of name=*, name:ht=*, name:en=*... tags and translating as appropriate to populate multilingual variants as applicable. Also I would anticipate that multinational support will be providing aid from Latin America as well, e.g. Spanish - name:es=* and Brazilian UN peacekeeping troops name:pt=* to support Portuguese.

Effort should be made to include properly accented characters. Users who don't normally use accented characters can cut-and-paste these from other features, or look up how to use a different character set with your keyboard (example).

Idées complémentaires

• large open spaces to serve as relief operation areas
• food distribution points
• How to map tent hospitals, hospitals in ships in the harbour, drinking water production places?
• Map village names from Public Domain CIA Maps. Sample WMS link suitable for JOSM OpenStreetMap Editor. Important for orientation.
• Water and sanitation features are crucial
• Someone should check at least all the main roads (red and yellow) if all the bridges/fords are marked as such. Not only in the Port-au-prince area, but everywhere. And if you find a bridge without a mapped river below, please mark a bit of the river as well.

Liste des erreurs corrigées

Frequently updating errorlogs you can find here. The C06-Check find river and streets crossing and having the same layer. Normaly the street has a bridge over the river. Tagging the bridge is important because after the eathquake every bridge can be damaged or out of use. So fix the bridges meaning making better data for routing. Quite a lot of minor crossings are fords, please use highres imagery to identify and tag (make a crossing node and tag just that node with highway=ford).
