The experienced GIS practitioners of Clove Tech offer customized project-based 3D elevation models with accurately computed geographic details using high-resolution Lidar/ Aerial Imagery. While our height maps can be represented in raster or vector data, here are the types of GIS data models.
- DSM (Digital Surface Model) DSM captures the height values of natural and constructed structures on earth’s surface or above DTM. It is fundamentally LiDAR delivered top massive point cloud filled with variable elevation values, which is ultimately a topographic model of the surface. A detailed feature-extruded DSM is used for urban and aviation planning, landscape Modeling, vegetation management, augmented simulation and other visualization applications.
- DTM (Digital Terrain Model) Portraying a topographic model of terrain surface in a 3D depiction including the heights & elevations of its geographical elements as well as natural landscapes. This can often be achieved by removing man-made and vegetation features from a DSM. We document the terrain roughness, vertical resolution, topography, terrain analysis algorithm and grid resolution details to produce accurate terrain morphology of the ground.
- DEM (Digital Elevation Model) Unlike discrete objects, surfaces are incessant phenomenon and to model them, we often need immeasurable amount of cloud points. A Digital Elevation Model is the simplest topographical representation of earth. It is a bare-earth raster GIS layer where neither the natural elements (trees, vegetation, etc) nor the man-made elements (building, bridges, towers, etc) are included in this model. These models are useful while measuring terrain stability, hydrology modelling, soil maps and other land use planning.
