Extraction of elevations for your 3D mapping workflows

  Services

Earth imagery is used for the creation of information products such as elevation models. Digital Elevation Models are created from point data that contain the longitude, latitude and height coordinates on the surface of the earth. Magnasoft provides all sorts of high-accuracy elevation models for your 3D mapping workflows. In addition to creating the right type of surface model that meets your needs, we offer tailored digital elevation modeling, digital surface modeling services for specific industry applications such as urban mapping, forestry, land management and mining.

Different types of DEMs and their uses

Other than 2D maps that often contain no height data,  digital elevation models show the elevation, which is valuable information for 3D mapping workflows where objects are mapped in a 3D space, where height information is crucial to map them correctly.

There are many DEM variants, such as DTMs, DSMs and DHMs. DSM extraction includes all manmade objects on the surface of the earth, such as buildings, powerlines, bridges, vegetation, other permanent and temporary objects, while Digital Terrain Modeling involves collecting mass points of elevations and 3D breaklines at each change of terrain. These mass points are collected at a grid spacing that meets project requirements. DTM extraction enables the generation of contours that meet specific standards.

DEM data extraction is widely used in GIS for studying geology, relief maps, land-based studies, flood modeling and similar. Height information can be derived from remotely sensed stereo imagery using a photogrammetric technique that determines elevations from imagery that is collected from two points of view with an overlap between both. Another way for performing Digital Elevation modeling is to extract points from LiDAR data or interferometric synthetic aperture radar (IFSAR).
