| Abstract | The generation of digital elevation models (DEMs) from the Standard imaging mode of RADARSAT-1 stereo-images was investigated to evaluate the viability of producing 1:100,000 scale altimetric maps in areas with a low topographic relief on the Brazilian Amazon coastal plain. Absolute DEMs were generated using RADARSAT-1 Standard stereopairs (S2Asc/S1Des, S6Des/S1Des, and S7Asc/S6Des) with ground control points collected using a Differential Global Positioning system. The geometric modeling for the DEM extractions was based on the RADARSAT Specific Model from the OrthoEngine Satellite Edition of the PCI Geomatica software; this model is an automated matching solution that considers the slant range distances from sensors and terrain. Thirteen independent control points were used to validate the accuracy of the absolute DEM. Only the S2Asc/S1Des pair was effective in highlighting depth information, which was a result of the pairs intermediate intersection angle (47◦) and higher vertical parallax ratio (4.31). Therefore, RADARSAT-1 Standard images are a useful alternative for generating absolute DEM at the scale of 1:100,000 in cartographic gap areas on the Amazon coastal plain. | |||
