I know of several places to get data, but I thought I'd see where others find data. It just seems like there are SO MANY sites. What are people's "go-to" sites when they need to find any data? Shapefiles, DEMs, imagery...anything.

Seamless server. Good but quirky.

I know of several places to get data, but I thought I'd see where others find data. It just seems like there are SO MANY sites. What are people's "go-to" sites when they need to find any data? Shapefiles, DEMs, imagery...anything.

Some places I've used are:

data.gov/

datagateway.nrcs.usda.gov/

soildatamart.nrcs.usda.gov/

GIS Servers

gdw.apfo.usda.gov

Web Map Service NFHL on hazards.fema.gov

mrdata.usgs.gov

ERDAS APOLLO Essentials - Image Web Server on iws.erdas.com

heres some data on haiti - Basemap Vector Layers for Haiti on apollopro.erdas.com

then theres always esri too - arcgis on services.arcgisonline.com

cant remeber what I used this for - bure.unep-wcmc.org

and try this one for Google Earth - https://hazards.fema...LWMSkmzdownload or http://www.floodsmart.gov

Im really interested to see what others have found. Personally I have just started to look for a regional (county, zip code, tract, block or what ever) median housing price data set, preferably going back to 1920-30 range. Everything I have found so far does not have the detail I would like or lacks the spatial component to map it. I still need to do some more searching on the census site though.

There are sooo many, it is impossible to list them all here. I generally use state and county websites as my projects are small and they usually have more up-to-date data and often, more accurate. If I were you, I would search for the county gis department in the area you are working in and start there. Good luck! :)

Because I do mostly large-scale work, I usually just Goggle "[placename] GIS" to see what comes up from actual local governments. Then I work my way up to the state GIS clearinghouse to see what else they might have.

For statewide data sets, the old "Starting the Hunt" website at the University of Arkansas has evolved into this:

Have you looked at the National Historical Geographic Information System? Keep in mind that we didn't have census tracts nationwide until the 1940 Census.

a lot is listed here:

http://grass.osgeo.o...Global_datasets

one of the biggest problem of most sites which provide downloadable data in my oppinion is the lack of clear license information. even if the basic data is in the public domain, the processed data often seems to be under another licencse.

here another useful site:
