text: The Shuttle Radar Topography Mission (SRTM) collected topographic data of
the Earth aboard the space shuttle Endeavour during its STS-99 mission
which was flown February 11 through 22, 2000. The mission was an
international project designed to generate a near-global digital elevation
model (DEM) of the Earth using radar interferometry. SRTM utilized
single-pass interferometry which compared two radar signals taken at
different angles. The C-band antennas transmitted and received radar at a
wavelength of 5.6 centimeters. One antenna was located in the shuttle's
payload bay, and the other on the end of a 60-meter (200-foot) mast that
extended from the payload pay once the Shuttle was in space. SRTM collected
C-band radar data in swaths, with a swath width (width of the radar beam on
Earth's surface) of 225 kilometers (km) from an altitude of 233 km. The
C-band radar acquired during the mission was processed by the National
Aeronautics and Space Administration (NASA) and the National
Geospatial-Intelligence Agency (NGA).

Endeavour orbited Earth 16 times each day during the 11-day mission,
completing 176 orbits. SRTM successfully collected radar data over 80
percent of the Earth's land surface between 60° North and 56° South
latitude. The C-band data were processed at the Jet Propulsion Laboratory
to make a near-global topographic map of the Earth.
