AB  - SRTM sensors have two bands, C-band and X-band, and the SRTMs we are using now are from the C-band. The publicly released SRTM digital elevation products include three different resolutions of DEM data: SRTM1 covers only the continental United States with a spatial resolution of 1s, SRTM3 covers the whole world with a spatial resolution of 3s, which is the most widely used dataset at present, and the elevation datum of SRTM3 is the geoid of EGM96, and the plane datum is WGS84; The nominal absolute elevation accuracy is ±16m and the absolute planimetric accuracy is ±20m. SRTM30 data also cover the whole world with a resolution of 30s.
