%X SRTM sensors have two bands, namely C-band and X-band. The SRTM we use now is from C-band. The published SRTM digital elevation products include three kinds of DEM data with different resolutions: srtm1 covers only the U.S. mainland, and its spatial resolution is 1s; SRTM3 covers the world, and its spatial resolution is 3S, This is the most widely used data set at present. The elevation datum of SRTM3 is the geoid of EGM96, and the plane datum is WGS84. The nominal absolute elevation precision is ± 16m, and the absolute plane precision is ± 20m. Srtm30 data also covers the world with a resolution of 30s.
