The purpose of the Landsat
program is to provide the world's scientists and application engineers with
a continuing stream of remote sensing data for monitoring and managing the
Earth's resources. Landsat 7 is the latest NASA satellite in a series that
has produced an uninterrupted multispectral record of the Earth's land surface
since 1972. Along with data acquisition and the USGS archival and distribution
systems, the program includes the data processing techniques required to
render the Landsat 7 data into a scientifically useful form. Special emphasis
has been placed on periodically refreshing the global data archive, maintaining
an accurate instrument calibration, providing data at reasonable prices,
and creating a public domain level one processing system that creates high
level products of superior quality.
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.
