| DATA COVERAGE
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%
of all the land on the Earth. |

| Land coverage: |
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 is a topography mission, so data were mostly acquired over land. Small amounts of data were collected over the water for calibration purposes.
