Digital Elevation Model DEM
A Digital Elevation Model (DEM) is a 3D representation of the Earth's surface that captures elevation data for terrain analysis and mapping. DEMs are widely used in Geographic Information Systems (GIS), remote sensing, environmental studies, urban planning, and engineering projects. By providing accurate elevation information, DEMs help users visualize landscapes, identify topographic features, and understand variations in terrain across different geographic regions.
DEM data supports a wide range of applications, including watershed management, flood risk assessment, slope and aspect analysis, infrastructure development, and land-use planning. Researchers, geographers, and decision-makers rely on Digital Elevation Models to generate contour maps, perform spatial analysis, and create realistic terrain visualizations. With high-resolution elevation data, DEMs play a crucial role in improving geographic analysis and supporting informed planning and resource management decisions.
