Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-12-16T00:00:00Z
The Terrestrial Development Index (TDI) quantifies the level of development (urban, agriculture, energy and mineral extraction and transmission, and transportation) based on the surface disturbance footprint. TDI values range from 0 to 100% and represent the total percentage of land surface occupied by the development footprint within a 1-kilometer (km) radius moving window.
