Executive Summary
Landsat represents the world’s longest continuously acquired collection of space-based moderate-resolution land remote-sensing data. The program’s imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
