Digital elevation model

A Digital Elevation Model (DEM) is a 3D representation of a terrain's surface, created using geographic data. It uses pixels to represent elevation, allowing us to visualize and analyze landforms like mountains, valleys, and plains. DEMs are vital in various fields, including environmental studies, urban planning, and disaster management, as they help assess flood risks, plan infrastructure, and understand natural landscapes. By converting complex topography into a digital format, DEMs provide valuable insights into land use, ecosystem management, and geospatial analysis.
