Digital Surface Model

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.

Key Features of the product

  • Automatic execution of the data with a defined workflow­
  • GCP File Creation: a semi-automatic tool for creating and editing GCPs 
  • Change Detection: identification of 3D changes ­ 
  • Stitching of DSM patches ­ 
  • DSM Inspection: generation of statistics about DSM quality ­ 
  • Point Cloud Colorization: colorization of a point cloud using a mosaic ­ 
  • Simple and user-friendly interface
  • An unlimited number of images can be processed
  • Survey-grade accuracy with detailed reports
  • Fast processing on GPUs and multi-core CPUs
  • Volume Calculation

Applications of a DSM

These models are used in planning, analysis, visualization, and modeling. 

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

What People Says About us

People

“Most attractive feature of SATPALDA’S DTM product is its suitability for engineering projects. Most accurate datasets are needed when the most sophisticated projects are handled. We cross-checked the accuracy value of the product at various parameters and always found it within the expected range. Keep it up ‘Team SATPALDA’.”

“This team is dedicated to the customer's need. Listening carefully to the requirements and customizing the product as per the customer's need is what I like about SATPALDA’’.
Hope to do many more projects together. Cheers.”

“During the execution of the 3D building project, I noticed the level of patience that SATPALDA has shown. We were not sure about the end-user requirement as he was a bit confused but credit goes to SATPALDA for giving the end-user a very clear and appropriate consultation on the output they needed.
We found the photogrammetry team at SATPALDA is very experienced and skilled as well”
