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...

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...
