Shuttle Radar Topography Mission
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.
Data StatisticsLand coverage: Targeted land was 80% of Earth landmass (119.56 M km2, 46.16 M mi2)
99.968% targeted land mapped at least once (119.51 M km2, 46.14 M mi2)94.59% targeted land mapped at least twice (113.10 M km2, 43.66 M mi2)49.25% targeted land mapped at least 3 times (58.59 M km2, 22.73 M mi2)24.10% targeted land mapped at least 4 times (28.81 M km2, 11.12 M mi2)
Land area missed:50,000 km2 (all in US)
Radar system acquired topographic data for >47.6 million miles2 of EarthTotal imaging time: ~10 days99.96% of planned coverage area mapped during STS-99 Space Shuttle missionSophisticated radar collected surface imaging data at a rate of 40,000 miles2 / min
