The "Broad-scale assessment of biophysical features in Colorado: Terrestrial development index using 5-kilometer moving window" raster dataset quantifies levels of development (urban, agriculture, energy and mineral extraction and transmission, and roads and railroads) for all lands in Colorado. The terrestrial development index (TDI) represents the total percentage of the estimated surface disturbance footprint from development within a 5-kilometer (km) radius moving window. The TDI scores range from 0 to 100 percent. Methods are described in the companion report (see "Larger Work" section).
This dataset includes results of the Trend Departure Index (TDI) for 139 sites in the RESTORE trend analysis study and approximately 9,200 HUC12 pour points in the streamflow alteration study. Data from the 139 sites in the trend analysis were compared against reference site data from the GAGES II dataset (Falcone and others, 2010) and were used to calculate the departure from reference conditions. The streamflow alteration study used pre- and post-periods of analysis to quantify hydrologic alteration in terms of a ratio. The TDI is a ratio of the difference between two sites divided by 365 (total number of trends per site). TDI varies from 0 to 1; a TDI of 0 indicates the trend results for the site are identical...

Potential for oil and gas development in the Wyoming Basin Rapid Ecoregional Assessment project area in relationship to existing oil and gas well pads. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics appropriate for applications that potential users of the data may contemplate. The User is encouraged to carefully consider the content of the metadata file associated with these data. The BLM...

Terrestrial Development Index (TDI) for the Wyoming Basin REA project area. TDI scores are based on the percent of surface disturbance footprint from development within a 2.25km radius moving window for a 15m cell size. The TDI quantifies the total area of the surface disturbance footprint for five disturbance variable classes: transportation (roads, railroads), energy and minerals (oil and gas wells, wind turbines, mines), transmission structures (towers, transmission lines), and agriculture (pasture, cropland) and urban land covers. TDI scores range from 0 to 100 percent and were divided into seven classes for visualization purposes. Because the development scores are continuous, alternative classes can be used...

The “Biophysical assessment for indemnity selection of federal lands in Colorado: Development” dataset quantifies the estimated surface disturbance from development (urban, agriculture, energy and mineral extraction and transmission, and roads and railroads) at several analysis scales for each of 89 Indemnity Units. The Indemnity Units are federal lands, currently managed by the Bureau of Land Management (BLM), under consideration for transfer of ownership to the State of Colorado in compensation for federal lands not available for transfer at the time of statehood. The companion data release (see "Cross Reference" section) was used to summarize the surface disturbance from development (development footprint) at...

Information on the biophysical features of federal lands identified as suitable for transfer to the State of Colorado was requested by the Bureau of Land Management (BLM). This information is intended for use in conducting an environmental assessment prior to transfer of ownership (conveyance) to the State. The Enabling Act of 1864 provided for the conveyance of federal lands to the State for the support of schools. If designated lands were unavailable for transfer at the time of statehood, the Act provided for the transfer of alternative federal lands in compensation, using a process referred to as “school-land indemnity selection.” To initiate indemnity selection, the Colorado State Board of Land Commissioners...

Information on ecological communities, soil salinity, and land use was synthesized and summarized for all lands in Colorado. This biophysical information was requested by the Bureau of Land Management (BLM) for use in conducting an environmental assessment prior to the transfer of ownership (conveyance) of federal lands to the State of Colorado. The Enabling Act of 1864 provided for the conveyance of federal lands to the State for the support of schools. If designated lands were unavailable for transfer at the time of statehood in 1875, the Act provided for the transfer of alternative federal lands in compensation, using a process referred to as “school-land indemnity selection.” To initiate indemnity selection,...

The "Broad-scale assessment of biophysical features in Colorado: Terrestrial development index using 1-kilometer moving window" raster dataset quantifies levels of development (urban, agriculture, energy and mineral extraction and transmission, and roads and railroads) for all lands in Colorado. The terrestrial development index (TDI) represents the total percentage of the estimated surface disturbance footprint from development within a 1-kilometer (km) radius moving window. The TDI scores range from 0 to 100 percent. Methods are described in the companion report (see "Larger Work" section).
