It is statistically determined from a neighborhood of image cells mainly considering the phase and baseline stability. Thus it describes the precision relative to the surrounding. The determination of the absolute accuracy requires the consideration of reference measures. The purpose of the SRTM X-SAR Error Mosaic is to enable and facilitate access to and visualisation of DLR's SRTM data through standardized web services.
