GIS Shapefiles

The geographic information system (GIS) data files available for download below contain key spatial data for BLM's Solar Energy Program in GIS shapefile format. The shapefiles may be viewed in desktop GIS software that allows users to conduct sophisticated geospatial analyses. A GIS software application is required to use the data and is not supplied in these downloads. The shapefile format is supported by many commercial and open source GIS software applications.

Who Should Use the GIS Shapefiles and Why

The GIS shapefiles provide experienced GIS users with access to a wide variety of spatial data through commercial desktop mapping software that runs on their PCs, not on the Internet. After downloading, an Internet connection is not required to view and use the data; however, the data downloads for the shapefiles are large. Users with the required software can interact with the geospatial data and run sophisticated spatial analyses. Considerable expertise is required to use GIS software, which may require a commercial license.

Other options for viewing these data are available on the Solar Program Maps page.

Data File Descriptions

Exclusions are the focus of new data provided subsequent to Solar PEIS GIS Shapefiles available through the Solar PEIS website, with an emphasis on discerning among the different classes of exclusions as presented in the Solar PEIS ROD. Pending and authorized applications on BLM-administered lands across the entire six-state study area are also included where applicable (there are none in Colorado and Utah).

The data file descriptions available below include the locations within the six-state study area excluded from development under the BLM's Solar Energy Program. These files for individual states include the locations of Solar Energy Zones, Variance Lands, BLM-Administered Lands, and pending and authorized applications (if any) in the supporting data.

A list of data layers for each state is available below.

California (15 KB)
Colorado (14 KB)
Nevada (14 KB)
New Mexico (13 KB)

Download Data Files

The following files are compressed Zip file archives containing multiple files for each state. Separate data files are also provided below for the solar energy zones, the pending and authorized applications on BLM-administered lands across the entire six-state study area, and the variance applications.
Please Note: Some of these files are large and may involve long download times.

(For a list of authorized solar projects on BLM-administered lands as of December 2019, see BLM's Solar Energy Project Information spreadsheet. As updates become available, they can be accessed on BLM's Solar Energy page.)

Please Note: Geodatabases are the native format used for Solar Program data. Geospatial data in geodatabase format are available for use in ArcReader software.
