Google Earth Engine——SRTM V3产品（SRTM Plus）由NASA JPL提供，分辨率为1弧秒（约30米）。

The Shuttle Radar Topography Mission (SRTM, see Farr et al. 2007) digital elevation data is an international research effort that obtained digital elevation models on a near-global scale. This SRTM V3 product (SRTM Plus) is provided by NASA JPL at a resolution of 1 arc-second (approximately 30m).

This dataset has undergone a void-filling process using open-source data (ASTER GDEM2, GMTED2010, and NED), as opposed to other versions that contain voids or have been void-filled with commercial sources. For more information on the different versions see the SRTM Quick Guide.

航天飞机雷达地形任务（SRTM，见Farr等人，2007年）数字高程数据是一项国际研究工作，获得了接近全球范围的数字高程模型。这个SRTM V3产品（SRTM Plus）由NASA JPL提供，分辨率为1弧秒（约30米）。

这个数据集经历了一个使用开源数据（ASTER GDEM2、GMTED2010和NED）的空洞填充过程，而其他版本则包含空洞或用商业资源进行空洞填充。关于不同版本的更多信息，请参见SRTM快速指南。
