Carr, N.B., Leinwand, I.I.F., and Wood, D.J.A., 2016, A Multiscale Index of Landscape Intactness for the Western United States: U.S. Geological Survey data release, https://dx.doi.org/10.5066/F75H7DCW.

Summary

The terrestrial development index (TDI) quantifies levels of development (urban, agriculture, energy and mineral extraction and transmission, and transportation). TDI scores represent the total percentage of the development footprint within a 20-kilometer radius circular moving window. The Surface Disturbance Footprint from Development for the Western United States is used in the moving window analysis. The TDI scores range from 0-100%.

Purpose

The purpose of the terrestrial development index is to summarize the surface disturbance footprint from development within a specified circular moving window size. The 20-kilometer TDI provides the broad-scale context for development patterns and is used in conjunction with the TDI calculated using a 2.5-km radius to create the multiscale index of landscape intactness.
