|What Part of the Earth was Mapped?
The Shuttle Radar Topography Mission collected data over most of the land
surfaces that lay between 60 degrees north latitude and 54 degrees south
latitude. That's about 80 percent of all the land on Earth.
||Targetted land was 80% of Earth landmass (119.56 M km2, 46.16 M mi2)
99.968% targetted land mapped at least once (119.51 M km2, 46.14 M mi2)
94.59% targetted land mapped at least twice (113.10 M km2, 43.66 M mi2)
49.25% targetted land mapped at least 3 times (58.59 M km2, 22.73 M mi2)
24.10% targetted land mapped at least 4 times (28.81 M km2, 11.12 M mi2)
|Land area missed:
||50,000 km2 (all in US)
In the maps below, the colors of the swaths indicate the number of times the
area was imaged by SRTM. For land, one-time coverage is green, twice is
yellow-green and so on, as shown in the key at lower left. Over water, the
color code is in shades of blue as shown in the key at lower right. Areas in
red could not be mapped. SRTM, a topography mission, mostly acquired data over land.
Small amounts of data were collected over the water for calibration purposes.
