The Shuttle Radar Topography Mission (SRTM) obtains
high-resolution digitial topographic database of the Earth. The
instrument will operate within the cargo bay of the space
shuttle including a mast that extends 200 ft (60 m).
SRTM uses C-band and X-band interferometric synthetic aperture
radars (IFSARs) to acquire topographic data over 80% of Earth's land
mass (between 60N and 56S).
SRTM produces digital topographic map products which meet
Interferometric Terrain Height Data (ITHD)-2 specifications (30 meter
x 30 meter spatial sampling with 16 meter absolute vertical height
accuracy, 10 meter relative vertical height accuracy and 20 meter
absolute horizontal circular accuracy). All accuracies are quoted at
the 90% level, consistent with National Mapping Accuracy Standards.
The SRTM is managed from NASA's Jet Propulsion Laboratory (JPL). For
