The Landsat-7
Science Data User's Handbook is a living document prepared by the Landsat
Project Science Office at NASA's Goddard Space Flight Center in Greenbelt,
Maryland. Its purpose is to provide a basic understanding of the joint NASA/USGS
Landsat 7 program and to serve as a comprehensive resource for the Landsat
7 spacecraft, its payload, the ground processing system, and methodologies
for rendering Landsat 7 data into a form suitable for science.
