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 2.5 kilometer (km) radius circular moving window. The TDI scores range from 0-100%. The TDI scores between 0-1% represent areas with few roads or a very low density of oil and gas wells. The TDI scores between 1-3% often include low densities of oil and gas wells and roads, whereas development index scores above 3% represent moderate to high levels of development, including relatively large oil and gas fields, surface mines, agricultural fields, centers of urban development, and highway/interstate [...]

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 2.5-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.
