Welcome to the SRTM home page. The Shuttle Radar Topography Mission
(SRTM) obtained elevation data on a near-global scale to generate the
most complete high-resolution digital topographic database of Earth.
SRTM consisted of a specially modified radar system that flew onboard the
Space Shuttle Endeavour during an 11-day mission in February of 2000.
SRTM is an international project spearheaded by the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration
(NASA).
Australia Data Release
NASA has released the SRTM data set for Australia, New Zealand, and
numerous South Pacific islands. There are about 1200 data 'cells' in
this release, each measuring one by one degree of latitude and
longitude. They represent the final set of unedited data from the
SRTM mission to be released.
As with the other SRTM data for regions outside the United States the
new set is sampled at 3 arc-seconds, which is 1/1200th of a degree
of latitude and longitude, or about 90 meters (295 feet). Because of
persistent cloud cover many of the Pacific islands had previously been
very poorly mapped, if at all.
The new data are available for download from the USGS EROS Data Center
- see Public Data Distribution
for details. |
