Digital Object Identifier 10.32754/JMT.2019.1.06 37 12Abstract—This paper describes a workflow for digital terrain model extraction from aerial and satellite stereo imagery and its integration in GIS applications. The results obtained using aerial and satellite stereo scenes are presented and commented. Stereo scenes are oriented using an approximate model named parallel projection which is a model that gained popularity due to simplicity and precision. For the digital terrain model generation the points are automatically extracted in the images using a modified Harris correlation operator and their 3D coordinates are then calculated with parallel projection parameters. After the 3D surface generation the terrain model is used further for visibility analysis.
