What is Open Data?

Open data is the idea that certain data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control.

This site provides access to all of our published open data. ArcGIS Open Data can help you track environmental concerns across the globe or all the hiking trails in your community. With ArcGIS Open Data, you can view it, map it, style it, chart it, download it or share it. How you use it is entirely up to you!
