Launch Solar Mapper

NOTE: This tool was prepared to support the BLM 2012 Record of Decision that established the BLM's Western Solar Plan. Some layers may be out of date. The current status of exclusion and variance areas and solar energy zones should be confirmed with BLM Field Office staff in the applicable jurisdictions.


We have many updates planned. Please subscribe for e-mail updates if you want to be notified when new features are released.


Learn More About Solar Energy Environmental Mapper

The Solar Energy Environmental Mapper is an interactive web-based mapping tool providing access to information relevant to siting of utility-scale solar projects in the southwestern United States. Users can view map layers that were used to create the maps and conduct some analyses in the Solar Energy Development PEIS as well as map layers showing land use decisions associated with the Bureau of Land Management’s Solar Energy Program. The tool provides the ability to zoom and pan to areas of interest, and display and query data.


The Solar Energy Environmental Mapper provides users with fast, easy access to a wide variety of spatial data through a Web browser, requiring only limited and generally quick data and software downloads. The data content and capabilities of the Solar Energy Environmental Mapper will be expanded and improved over time, so it will provide the best access to updated, comprehensive data, and powerful analytical tools in an easy-to-use format.

System Requirements

The Solar Energy Environmental Mapper requires an active Internet connection while in use. It is compatible with leading, current, web browsers.
