Digital Surface Model
Digital Surface Model (DSM) represents the elevations of the reflective surfaces of trees, buildings, and other features elevated above the “Bare Earth”. It represents the earth’s surface and includes all objects on it.
We use algorithm-based high-end software that is patented to end-to-end photogrammetry solutions for the generation of high-quality geospatial data from satellite and aerial imagery, including UAVs. It builds on unique computer vision algorithms that significantly differ from traditional photogrammetry techniques. Powered by GPU technology and multi-core CPUs, it ensures matchless processing power to support the rapid production of large datasets.

Applications of a DSM
These models are used in planning, analysis, visualization, and modeling.
- Urban planning, architectural planning, tourism, virtual tours, etc.
- For improving the transportation system
- Telecommunication
- Flood risk analysis and many others.
- Runway Approach Zone Encroachment: DSMs in aviation can detect runway obstructions in the approach zone.
- Vegetation Monitoring: DSMs can identify where and how much vegetation is intruding on a transmission line.
- View Obstruction: DSM is being used by urban planners to evaluate how a proposed building will affect the viewsheds of businesses and residents.
