USGS is a primary source of Geographic Information Systems (GIS) Data. Our data and information is presented both spatially and geographically including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more. Start exploring by topic below.
Principal components of climate variation in the Desert Southwest for the time periods 1980-2010, 2040-2070 (RCP8.5) and (RCP4.5) - data release
Five principal components are used to represent the climate variation in an original set of 12 climate variables reflecting precipitation and temperature gradients. The dataset provides coverage for four regions (the Sonoran Desert, Mojave Desert, Colorado Plateau, and Southern Great Basin) and two time periods: current climate (defined as the 1980-2010 normal period) and future climate (...
Welcome to the CMGP Internet Map Server, an internet map server and downloadable list of GIS data being served by the USGS, Coastal and Marine Geology Program.
Here we explore environmental effects on GPS fix acquisition rates across environmental conditions and detection rates for bias correction of terrestrial GPS-derived large mammal habitat use. We also evaluate patterns in missing data that relate to potential animal activities that change the orientation of antennae and characterize home-range probability of GPS detection for four species.
