Geoplus Solutions’ in-house production team provides orthorectification and mosaic imagery services to enhance the accuracy of your project’s survey design (CAD file).
The orthorectification of satellite images uses high-precision field Ground control points or vector data (CAD/SHP) and DEM data. According to the RPC parameters provided by the image data, the remote sensing images are corrected for projection errors and geocoded through the RPC model.
Digital Elevation Models
Digital Elevation Models (DEMs) play a significant role in geospatial solutions. Our internal production experts are ready to provide two types of DEMs (DSM or DTM) for your satellite imagery-related 3D product requirement based on your specific project requirement.
Digital Terrain Model (DTM)
This variant of 3D model represents the bare ground surface without all the features, such as buildings and trees.
Digital Surface Model (DSM)
The Earth’s surface and includes all objects present on it. It incorporates the heights of cultural features like buildings, roads, and vegetation layers in the real world.
Applications
Experienced the Geoplus wide range DEM solutions for your valuable insights.
AIRBUS PROVIDES UNPRECEDENTED LEVEL OF DIGITAL ELEVATIONS SERIES
Digital Terrain Model
A DTM is a topographic model of the bare earth, or terrain relief, that contains spatial elevation data in a digital format. The data is presented as a rectangular grid without vegetation, buildings, and other man-made features on the ground. It focuses only on the depiction of natural terrain, excluding any artificial elements on the surface. DTMs analyse topography and landscapes in great detail and extract an accurate representation of elevation detail on the surface.
Digital Surface Model (DSM)
The Earth’s surface and includes all objects present on it. It incorporates the heights of cultural features like buildings, roads, and vegetation layers in the real world.
