Official Sources of Mapping Information

Great idea. As an FYI, the Illinois link sent in the original post is very old and should not be used to gather current information on streets.

Official Sources of Mapping Information

Postby jondrush » Mon Nov 28, 2011 5:28 pm

I'd like to start a stickied thread that will provide new editors a list of official sources of mapping information from their state governments. Please provide any resources you know of and I will edit this post as I get time. I'd prefer sources that do not require separate software to be downloaded beyond PDF readers and browser plug-ins. Unofficial sources can be listed too, but many of them are mash-ups and unstable or unreliable.

Yes, I'm trying to avoid third party vendors or viewers so we don't run afoul of any licensing issues. I know there are free GIS data viewers out there, but the one's I've looked at seem scammy or malware-like.

I'll go ahead and do so since the "Georgia" wiki page is currently blank. Thanks.

Great idea. Here are a few I've used in the past. Some are not compatible with Chrome.

Arkansas: GeoStor Viewer (statewide GIS/aerial imagery)
Illinois: General Highway Maps (b/w city and county map .pdfs, some very old)
Indiana: IndianaMap (statewide GIS/aerial imagery)
Indiana: State Transportation Map (.pdf of free tourist map)
Iowa: City and County maps (.pdfs of DOT-produced street maps, generally very current)
Kansas: County Maps and City Maps (.pdfs and .jpgs)
Kentucky: The Commonwealth Map (statewide GIS/aerial imagery) (ESRI)
Michigan: Michigan PR Finder (Physical Road finder: statewide GIS & aerial imagery)
Mississippi: Mississippi Geospatial Clearinghouse (statewide GIS/aerial imagery) (ESRI)
Missouri: County Maps (.pdfs of every county road map in the state)
Nebraska: Nebraska Imagery Lookup Map (statewide GIS/aerial imagery
Nebraska: State Highway Map (.pdf of free tourist map)
North Dakota: ND Hub Explorer (statewide GIS/aerial imagery)
Oklahoma: Oklahoma DEQ Data Viewer (statewide GIS/aerial imagery)
South Dakota: SDDOT Viewer (statewide GIS/aerial imagery) (ESRI)
West Virginia: Base Map Viewer (statewide GIS/aerial imagery)
Wyoming: WyGISC Data Server (statewide imagery; addl info via download)

Nationwide: US Census Bureau maps of all counties and incorporated places, listed by state (usually not as accurate as the above)
Nationwide: Beacon (approx 200 city/county local gov't GIS linked through vendor's site; mostly from midwestern states)

Many more exist for individual cities/counties if you desire to start another list. Actually, it would be easier for people to just search for "[cityname] GIS" and go from there.
