Purpose of Open Source GIS Data
The purpose of this website is to provide a place for people to find and utilize open source GIS data. From local government sources to globally available sources, this is the place to find them and learn how they can be used.
Topography, weather, hydrology, ecology, social, conflict, administrative and many more types of data are at your fingertips here.

I want to thank Joseph from mappingsupport.com for curating and maintaining his list of 3000+ ArcGIS rest servers. This list is one of the largest collections of federal, state, and local GIS data sources.
Next I would like to thank Ben Millard from cartobin.com for creating a web application with an API using Joseph's list of sources. Using this API has allowed me to easily add thousands of sources to this website for every state and US Federal Agency.
