Results for tag: "Digital Elevation Model"

A Digital Elevation Model (DEM) is a 3D representation of a terrain's surface, typically used in the context of Global Positioning Systems (GPS) software. DEMs are created from a variety of sources, including aerial photographs, satellite imagery, and lidar data. DEMs are used to create maps, analyze terrain, and simulate the effects of natural disasters. DEMs are also used to create 3D visualizations of terrain, which can be used for a variety of applications, such as urban planning, engineering, and environmental monitoring. The DEM market is growing rapidly, driven by the increasing demand for accurate terrain data and the need for more detailed 3D visualizations. The market is expected to benefit from the increasing adoption of GPS software and the development of new technologies, such as lidar and satellite imagery. Some of the major players in the DEM market include Esri, Hexagon Geospatial, Intermap Technologies, and DigitalGlobe. Show Less Read more
