When I work on GIS projects, I use this page to keep track of good sources I find for data. I have a page of Spatial Test Data sources that I use for testing OpenLayers.
World
Digital Chart of the World DCW converted to Arc/Info coverages in e00 format; request data for a region and this server will pack the data in a tar archive for your downloading.
CIA World DatabBank II downloadable data
The server is at the Penn State map library
Map of UTM zones
Global Land Cover Facility, Institute for Advanced Computer Studies, University of Maryland
Landsat, SRTM, more
Europe
GISwiki in German
France
North America
United States
Coastal NOAA USIEI = "US Interagency Elevation Inventory" (one stop shopping)
FEMA http://msc.fema.gov/
USDA NRCS Geospatial Data Gateway (2017-02 back online!!!)
SSURGO, climate data, LiDAR, NAIP imagery, US Census, all gathered in one place.
(2015-Aug-29 check these for currency.)
Harris Mapcart Free downloads of SDTS data
NASA Reverb|Echo
USGS 3DEP viewer (DEM, LiDAR) http://viewer.nationalmap.gov/basic/?basemap=b1&category=ned,nedsrc&title=3DEP%20View
USGS EarthExplorer
USGS National Map including USTopo
USGS National Water Information System (NWIS) mapper: http://maps.waterdata.usgs.gov/mapper/index.html
USGS Trails Explorer Seven ways to access trail data
Arizona
Arizona University GIS data
Arizona University OpenGeoPortal
AGIC
They refer to a NAIP point cloud
AZGEO requires registration for access, sign up now for free so you are ready when you need it. They did get back to me over a 3 day weekend though! Yay.
Arkansas
Big Woods Cache River Home of the Ivory Billed Woodpecker and a former US president.
California
California Division of Fish and Wildlife (CDFW) https://www.wildlife.ca.gov/Data/GIS/Clearinghouse
State of California Geo Portal
Data Depot -- California (Ignore the complaints about Silverlight, which is DEAD.
Northern California includes 48 counties, here are some of them. That's a lot of counties, I need a map. What a big state this is. I think there are 57 total.
- Alameda
- Amador
- Butte
- Colusa
- Contra Costa
- Del Norte
- El Dorado
- Glenn
- Humboldt
- Lake
- Lassen
- Marin
- Mendocino
- Modoc
- Napa
- Nevada
- Plumas
- Sacramento
- Santa Clara
- Shasta
- Sierra
- Siskiyou
- Solano
- Sonoma
- Sutter
- Tehama
- Trinity
- Yolo
- Yuba
What happens if I drop a First Draft GIS map in here?
<html> <iframe width="500" height="300" src="https://firstdraftgis.com/">A map should appear here.</iframe> </html>
Alameda
https://data.acgov.org/browse?category=Geospatial%20Data
City of Pleasanton has a tiny bit here: http://www.cityofpleasantonca.gov/gov/depts/gis.asp
Contra Costa
http://www.co.contra-costa.ca.us/1818/Maps-GIS *requires registration (when GIS data is outlawed only outlaws will have GIS data!)
When you want data from the county site and it says "it's not here", then go here instead: ftp://atlas.ca.gov/pub/coco-county/
Marin county
MarinMap is the county consortium site. Lots of data here.
They have TIFF and MrSID format 6" aerial photos for the entire county. You can download a vector grid to determine which tiles you need.
Mendocino county
"The County does not offer public access to interactive GIS information, but you may contact the County's Information Services Department at (707) 463-7200 and ask for 'GIS' for more information regarding GIS data layers."
http://www.co.mendocino.ca.us/planning/CountyMaps.htm has PDF maps
Monterey county
Monterey county's GIS office is in Salinas The county uploads all its data to arcgis.com. http://montereycountyopendata.montereyco.opendata.arcgis.com/
Napa county
county: NOT HERE: http://gis.napa.ca.gov/
but here: http://gis.napa.ca.gov/giscatalog/catalog.asp Napa County GIS catalog
Napa County Resource Conservation District http://naparcd.org/resources-documents/mapping-tools/
Santa Clara
County of Santa Clara GIS data You must file a request to get centerline and parcel data. Other than the request form they have links to other sites. You can view their data in a map viewer but no direct download facility exists.
Santa Clara Valley Water District GIS data Their data is in arcgis.com but they have links to other sites here.
Santa Cruz
Search in arcgis.com under "Santa Cruz County Open Data".
Solano
To build a map quickly your best bet is to load layers directly from ArcGIS Online, that's how they are making available most of their vector data.
http://regis.solanocounty.com/ http://solano-doitgis.opendata.arcgis.com/
Aerial photo server http://regis.solanocounty.com/server/rest/services/AerialPhotography/Aerial2015/ImageServer
Cities in Solano county
- Benicia
- City of Vacaville GIS: http://www.ci.vacaville.ca.us/departments/information-technology/geographic-information-system-gis They have a few thematic PDF maps up on their site and link to ArcGIS Online for a basemap viewer.
- Vallejo
- Winters
- Woodland
Sonoma county
PRMD downloads (PRMD = Permit and Resource Management Dept.)
Sonoma VEG map Vegetation, Habitat & LIDAR data for Sonoma County
Sonoma County GIS Data Portal download site
LiDAR and orthos: ArcGIS REST service http://mangrove.cnr.berkeley.edu/arcgis/rest/services/
or perhaps http://mangrove.cnr.berkeley.edu/arcgis/rest/services/SONOMA_HYDROFLATTENED_BARE_EARTH_HILLSHADE/ImageServer
Hillshade in QGIS
Create a gdal service description file, e.g. by running this in a terminal:
gdal_translate "http://mangrove.cnr.berkeley.edu/arcgis/rest/services/SONOMA_HYDROFLATTENED_BARE_EARTH_HILLSHADE/ImageServer?f=json&pretty=true" s.xml -of WMS
You can now load this file into QGIS, e.g. by drag-and-drop.
Yolo county
"Yolo GIS Cooperative The County of Yolo, the cities of Davis, Woodland, Winters, and West Sacramento along with Sacramento Area Council of Governments (SACOG) are working jointly as a cooperative to develop shared GIS data layers and maintaining shared regional GIS resources. Current projects include maintenance of a county-wide tax parcel data layer, road centerline data, jurisdictional and spheres of influence. "
