AbstractDigital elevation models (DEMs) provide a digital representation of the Earth's relief, and are used in a variety of applications in geo-spatial analysis. Elevation data as DEMs are required to produce geocoded, orthorectified raster images, which often are incorporated in a geographic information system. The atmospheric, geometric, and radiometric correction of satellite data from optical and microwave instruments also require topographic information. Satellite data-derived DEMs form a vibrant research and development (R&D) topic for the last 30 years since the launch of the first civilian remote sensing satellite (Toutin 2000). Various methods exist to extract DEMs from both active and passive sensor-based satellite data-derived images (clinometry, stereoscopy, interferometry, polarimetry, and altimetry).
