I like to make maps.
I also participated in HOT's exploratory mission to Senegal, may-june 2012. With HOT in Haiti, on Cap Haitian/#CAP103 program, May-June 2013.
Stuff below is notes for newbies, things that I've learned as I become more experienced w/ OSM reference and that other newbies in the USA may need:
Notes for newbies: - Tags are not very strict and can be up for interpretation.
If in doubt of what to use, check here and also ask at help.openstreetmap.org
To tag a 'neighborhood' in US, use the place=suburb tag. (sounds counterintuitive to use suburb, but you'll find that the literal meaning of a definition is different than its meaning in OSM).
Tag:highway=service is for turnpike rest areas,
tag:building=mixed_use for buildings that have multiple uses in them; often found in cities that have retail on the ground floor and would have residential on upper floors. [THIS IS debated]

cemetery is more popular than graveyard: http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dcemetery
ways with no names in Cleveland: http://random.dev.openstreetmap.org/no-names/?zoom=13&lat=41.48725&lon=-81.68665&layers=0B000
access=private for roads that are private, that you, an average person do not have legal access to.
JOSM: how should I edit a way when the admin boundary is directly over the way i want to edit ? I haven't figured out how to select only the way not the boundary A: If you have a mouse with a middle button, click on the way and then ctrl+click it on that list; middle click and then hold Ctrl to select the one you want; also you can hide things with the filter button.
The terms on OSM are a bit British in their usage.
- I interpret it as places [with no, or minimal stands] to play sports in the USA. 'leisure=pitch', Outdoor public tennis, basketball courts, baseball fields in parks, you would tag them as leisure=pitch
- not sure with the difference with Parks and recreation grounds. http://wiki.openstreetmap.org/wiki/Tag:landuse%3Drecreation_ground ??!
- leisure=sports_centre - use this for indoor facilities [like a Y ? but at city rec centers, they have stuff besides sports, community_centre ?].
highway=motorway_link are what Americans call on-ramps and off-ramps.
Motorways is the term used in OSM that Americans would often call Highways or Freeways
Difference between highway=footway and Tag:highway=pedestrian : pedestrian is large enough where a car could go travel on it, but cars are usually restricted from it. [footway, I'd use for typical American sidewalks]... also see this

<Firefishy> Yes, I de-activated the wiki page view thing. Real resource hog. I can run stats from logs if needed. (in reference to gathering stats like 'which wiki page has the most views' etc)
- farmer's markets, you could you use amenity=marketplace
for tagging roads that go underneath buildings (like the one in uptown at university) http://wiki.openstreetmap.org/wiki/Tunnel (tunnel=building_passage)
US Road differences http://wiki.openstreetmap.org/wiki/United_States_roads_tagging#U.S._Highways
Difference between drain and ditch ? (There were open air sewers in senegal where sewage and rainwater would be transported). [from Achadwick waterway=drain for big concrete ones or waterway=ditch for little muddy ones. As for the open sewer aspect... not sure. It may be necessary to invent tags]
for flooding areas; rivers, streams that aren't there all the time... intermittent=yes http://wiki.openstreetmap.org/wiki/Tag:waterway%3Driverbank#Varying_water_level_river
Disused things: disused=yes disused:amenity=parking disused:capacity=20
difference between osm2pgsql and osm2postgresl ? - 2 different programs, they each do similar things: both can set up your data in .osm format to a postgis db so you can use the data in tilemilL - osm2pgsql is much more popular and has more support.
A municipality with a population over 100,000 isn't automatically eligible to be place=city ?
The current tag structure has place=city as the largest municipality area, so in the case of Miami being the largest in population in the surrounding and I'd argue, more subjectively, the most prominent and famous, in the area, that cities
for things like pizza places or chinese restaurants in the states that do take-out, this looks to be a good scheme to use: amenity=fast_food takeaway=yes delivery=yes/no re: http://firstname.lastname@example.org/msg00451.html
Questions that I've asked
-why aren't all landuses [i.e. http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dorchard ] listed in josm ? A. There's a default preset chosen by josm developers. you can modify this if you want by modifying the presets file.
Q: I'm curious to find out the total length of all of the ways that have X Key/value (for example, footways) within an osm area or a bounding box. is there a tool that does this ? A: Not in OSM directly. Best off changing that data to a SHP or postgis db and go from there.
select nodes that are not in a way in JOSM:
search "type:node -(child type:way)" works - tip from <Gnonthgol>
- difference between locality and hamlet ?
Locality is used when no one lives there. Hamlet is when there's a small population a couple hundred.
how can I find out tagging for chain places like lowe's, gamestop, bed, bath, and beyond where I'm unsure of what tags to use ?!
(What I've been using):
GMC - shop=nutrition_supplements (had more than anything else containing vitamin or nutrition)
Bed, Bath, and Beyond - shop=houseware
(Bath and Body Works, shop=soap ? )
shop=video_games had 101, more than what already had been established for http://wiki.openstreetmap.org/wiki/Tag:shop%3Dwindow_blind
shop=beauty_supply for places that sell hair extensions, hair care products, etc (Sally Beauty Supply)
for nail salons; shop=beauty and beauty=nails
for payday loans, shop=money_lender

-how do i close a changeset that I made ?
- automatically closes after an hour or 90 minutes of inactivity, I think.
- should I include a building=yes for amenities like schools, libraries, if I am drawing the nodes of them ? If I include the tag, then the rendering for building=yes overrides any other tag [at least in mapnik]?
- Is there a clearly legible list what content (And what tags) that are rendered in main OSM stylesheet ?
- wiki wise, when creating new articles, use underscores for spaces instead of dashes or hyphens.
- What to use to tag juice places like Jamba Juice? (I used amenity=fast_food ; cuisine=juice )
- what to use to tag bail bondsmen? (bonds, when you need to release someone from jail).
edit later into the wiki
<skorasaurus> http://lists.openstreetmap.org/pipermail/osmosis-dev/2011-April/000996.html <mmitchell> skorasaurus: no problem, i'm learning anyhow so all is good :) <apmon_> parent relations of a way / relation are those relations that contain the way / relation as a member
- skorasaurus aha, guess I'll add that to the wiki
<skorasaurus> apmon_: parent relations are the same thing as super relations ?
- geohacker (~email@example.com) has joined #osm-dev
<mmitchell> ok another osmosis (maybe it's osm2pgsql?) question that I have is... why do i have duplicate, negative osm_ids in my planet_osm_polygon table?
- simonpoole_ has quit (Ping timeout: 480 seconds)
<balrog-k2n> negative ids are the IDs of relations converted to polygons <balrog-k2n> as opposed to ways, which are left with the original id <balrog-k2n> duplicate, i don't know (shouldn't happen with osm2pgsql normally, i think) <balrog-k2n> the negative id is just an implementation detail, not important <apmon_> duplicate negative ids happen if a multipolygon relation contains several distinct polygons <apmon_> e.g. an exclave of an administrative area �18�<��26mmitchell�>�� balrog-k2n apmon_ ah ok, i was just reading something about this. So, I'm assuming I'd have to "join" the multi rows back together for a complete multi-polygon record? How can I do that? �18�<��26mmitchell�>�� (postgres w/postgis extension) �18�<��25apmon_�>�� I think there is an option for that during import in osm2pgsql. But I haven't tried that so can't give you details �18�<��26mmitchell�>�� apmon_: cool i'll look into that, thanks �18�<��26Komzpa�>�� mmitchell: -G option
(mmitchell wanted to get the boundary polygons w/in a specific bounding box..)
[a-zA-Z] for I want to find stuff like name:ABCD in josm.
Ask how to tag some damn American chain stores:
- Lowe's - marshall's - Wal-mart - K-Mart - Target
- also [go-kart tracks http://lists.openstreetmap.org/pipermail/tagging/2011-January/006460.html]
also batting cages (I found leisure=practice_pitch perhaps) Proposed_features/Practice_pitch
searching on taginfo took forever. http://taginfo.openstreetmap.org/search?q=name%3Dmarshall%27smerge place=neighbourhood and neighbourhood wiki articles.
- write a tutorial if there isn't one already: 'what do I do if there if I don't know what to tag do something or if I find conflicting information ?'
add to http://wiki.openstreetmap.org/wiki/FAQ the question 'How do I make my own map for my website, to print out using OSM data ?'
- http://wiki.openstreetmap.org/wiki/User:Sarchittuorg/Note - to filter for the cleveland nh map; to extract features w/in polygon .
http://www.openstreetmap.org/?lat=13.369922&lon=18.36718&zoom=19 - what is this ?
amenity=ice_cream or amenity=cafe and cuisine=ice_cream ?
Imports that I have done: importing data from TIGER 2010 for Great Lakes (USA) coastlines, for odbl cleanup. (DONE) http://lists.openstreetmap.org/pipermail/imports/2012-March/001299.html
