What Does DEM Stand For?
DEM stands for Digital Elevation Model
DEM, or Digital Elevation Model, is a 3D representation of terrain surface created from elevation data, providing a digital depiction of the Earth's surface. It is commonly used in geographic information systems (GIS), surveying, and remote sensing to analyze topography, assess land use, model water flow, and support various environmental studies and planning applications. DEMs can be generated from various data sources, including satellite imagery, aerial surveys, and lidar technology, offering valuable insights for numerous scientific, engineering, and urban development projects.
