Geographic Information System (GIS) Shapefiles
Data files used in the PEIS analysis in GIS shapefile format available for experienced GIS users interested in detailed PEIS analysis.
Use the links below to download key spatial data used in the Draft Solar PEIS and Supplement to the Draft Solar PEIS analyses, for use 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 very 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 often requires a commercial license. The data included may be downloaded for other uses, but only provide a “snapshot” of data used for the PEIS, and will not be updated or expanded after the PEIS is completed.
Data File Descriptions
The “core” data download includes boundaries of the modified alternatives as presented in the Supplement to the Draft PEIS, boundaries of protected lands and other areas excluded from solar energy development under one or more of the alternatives, and base data such as state boundaries, towns, and roads.
The “extended” data download includes all of the “core” data as well as the Public Land Survey System (principal meridians, townships, and sections) for the six state area.
A listing of data layers included in both the “core” and “extended” data downloads is available.
Download Data Files
GIS Data Files for the Draft Solar PEIS: The following files are compressed Zip file archives containing multiple files. PLEASE NOTE: These files are extremely large and may involve very long download times.
AS OF THE RELEASE OF THE SUPPLEMENT (OCT. 27, 2011) THESE FILES ARE NO LONGER CURRENT UNLESS UPDATED WITH THE SUPPLEMENT DATA FILE PROVIDED BELOW.
New GIS Data Files for the Supplement to the Draft Solar PEIS: GIS data for Areas of Critical Environmental Concern (ACEC,) Special Recreation Management Areas (SRMAs,) and National Monuments has been updated for the Supplement to the Draft Solar PEIS. These data, as well as GIS data for lands available for Solar Energy ROW Authorizations under the No-Action and Modified BLM Action Alternatives, are available below. (Note that small changes to the no action alternative lands occurred due to updated GIS data for National Monuments.)
This file provides updates to the GIS data files previously offered. There is no need to download Solar PEIS Shapefile data. zip or Solar PEIS Extended Shapefile data.zip, again. Instead, download the GIS data below and use it to update the previous data as needed.
Note that a change from the Draft Solar PEIS is that otherwise appropriate areas of less than 1 km2 are now included under the modified BLM program alternative. Addition of these areas sometimes results in the appearance of long polygons which have almost no width when the data is displayed at larger scales. These line segments are the result of inaccuracies due to digitizing errors, difference in source materials, or datum shifts in the varied geospatial datasets used in developing the alternatives.
New Data for Desert Tortoise Areas: The Supplement to the Draft Solar PEIS presented information on the locations of Desert Tortoise Conservation Areas and Desert Tortoise Connectivity Areas (see Chapter 2 of the Draft PEIS). The GIS data showing specific locations of these areas are available below.
PLEASE NOTE: Geodatabases are the native format used in the Solar PEIS database. Geospatial data in geodatabase format is available for use in ArcReader software.
