This is a map of populated areas with population density greater than or equal to 1 individual/ha (i.e., rural/exurban but including suburban and urban as defined by Marzluff et al. 2001) as determined from U.S. Census data corrected for public lands.
This map depicts the proportion of non-Sage-grouse habitat within 54km of each pixel. The map was produced using a moving window analysis on the Distribution of Non-Sage Grouse Habitat in the Conservation Assessment Area with a search radius of 54km. The product of the moving window was the mean pixel value within the window. This map has a 540m resolution.
Cellular phone microwave towers registered with the U.S. Federal Communications Commission. Not all antennas are required to be registered with the FCC, therefore, this data set does not necessarily depict all cellular phone communication towers actually present on the landscape. The source data are updated weekly by the FCC as new permits are issued. However, this particular data set is designed for a specific analysis, and is planned to remain static as of the publication date (11/06/2003).
All secondary roads in the western United States from the 2000 US Census TIGER/line files. Secondary roads are defined as all roadways not classified as an interstate, state highway, or federal highway.
