Generation of Digital Elevation Models with High-Resolution Optical Satellite Images

The SPOT family of satellites is made up of a constellation of Earth observation satellites. SPOT satellites have the ability to capture stereoscopic images of the same portion of land, whichallows the extraction of digital elevationmodels (DEM). This paperdescribes the process for extractingDEMsfrom SPOT-6 satellite images, whichincrease the ability to obtainresultswithhigherresolution at a scale of 1/10,000; the study area includes the province of Caylloma in the department of Arequipa. The digital model obtainedwillbeusedlater in the generation of interferograms to detect changes and/or deformation in the Macalandslide
