Terrain Modeling (DTM) Services
SATPALDA specializes in creating highly detailed Digital Terrain Models (DTMs) for a wide range of applications. A DTM is a topographic model of the bare earth, or terrain relief, that contains spatial elevation data in a digital format. The data files are presented as a rectangular grid and vegetation, buildings, and other man-made features are removed digitally. Our DTM`s are used for contour generation, orthophoto rectification, flood plain mapping and digital elevation models (DEMs) and 3D modeling, volumetric calculations, and powerline surveys. We use sophisticated post-processing tools and methods to detect errors and anomalies in DTM and to generate clean contours, TIN or other deliverables. The final delivery is in a client-specific format.
We generate DTMs/DSMs from a variety of satellite images, including WorldView-3, GeoEye-1, WorldView-1, WorldView-2, Ikonos and ALOS PRISM stereo satellite images, allowing us to deliver high-quality results for a wide range of projects. Our optional automatic procedure extracts DTM points from stereo pair images, generating a large number of DTM points by going through a pyramidal data structure and robust DTM modeling.
