U.S. National Atlas Urbanized Areas represents urban areas in the United States derived from the urban areas layer of the Digital Chart of the World (DCW).

U.S. National Atlas Cities represents cities and towns in the United States.This dataset was used in the Northern Great Basin Rapid Ecoregional Assessment by BLM. No changes were made to the data but the dataset reduced to only included certain cities/towns within the ecoregion.

The TNC Ecoregional Portfolio Core Data Set is one of a set of Core Conservation Data Sets managed in GIS by The Nature Conservancy's network of Conservation Data Nodes. This Core Data Set will enable TNC to more effectively deliver data and products of ecoregional assessments to key conservation partners. The data set is being developed in phases. The first phase aggregates all maps of terrestrial ecoregional portfolios developed by The Conservancy across the fifty United States. Subsequent phases of this data set will include biodiversity conservation targets (species and ecosystems) and goals for their conservation, as well as adding existing freshwater and marine portfolios to the terrestrial portfolio developed...

This USGS data release represents geospatial data for the sage-grouse habitat mapping project. This study provides timely and highly useful information about greater sage-grouse over a large area of the Great Basin. USGS researchers and their colleagues created a template for combining landscape-scale occurrence or abundance data with habitat selection data in order to identify areas most critical to sustaining populations of species of conservation concern. The template also identifies those areas where land use changes have minimal impact. To inform greater sage-grouse conservation planning, the researchers developed greater sage-grouse habitat management categories based on habitat selection indices (HSI) and...

As part of a NASA-funded study of diurnal thermal imaging at a Mars analog site, we conducted simultaneous oblique thermal imaging and in situ temperature measurements within two regions of interest on the Pisgah lava field, near Ludlow, California. Both regions of interest contained either cave or cave-like alcoves. Data released in this report was collected from 03/23/2010 to 03/25/2010. The experiment was conducted at Pisgah lava field, which is located about 175 miles northeast of Los Angeles on Bureau of Land Management lands. Consisting of Quaternary basaltic lava and a cinder cone superimposed on alluvial deposits and lacustrine sediments of Lavic Lake playa (Dibblee, 1966), the flow is approximately 21,000...

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...
