Shuttle Radar Topography Mission (SRTM)

This is the SRTM dataset. 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).

本数据集为航天飞机雷达地形测绘任务（Shuttle Radar Topography Mission，SRTM）数据集。该任务以近乎全球范围获取高程数据，以此构建了迄今最完整的高分辨率地球数字地形数据库。SRTM由一套经过特殊改装的雷达系统组成，该系统于2000年2月搭载奋进号航天飞机执行了为期11天的测绘任务。

SRTM是由美国国家地理空间情报局（National Geospatial-Intelligence Agency，NGA）与美国国家航空航天局（National Aeronautics and Space Administration，NASA）牵头开展的国际合作项目。
