Abstract
Currently, space image data of the earth's surface is being primarily used with emphasis on two-dimensional information content. Three-dimensional image data acquisition is now emerging through the multi-lateral viewing capability of new spaceborne VISIBLE/INFRARED and SAR imaging systems. While visual relief perception from stereo pairs is easily achievable using low-level processed data, more advanced digital stereo processing techniques can be used as versatile tools to extract information out of three-dimensional input data. A completely automated approach will be presented for digital generation of elevation data from stereo pairs. The emphasis will be on the reliability and precision of results obtained from digital image data.
