Elevation mapping refers to the process of creating a map or model of the Earth's surface that shows the elevation or altitude of different points or areas. This can be done using various techniques such as satellite imagery, radar, LiDAR (Light Detection and Ranging), or surveying. Elevation maps are useful for a variety of applications, including urban planning, natural resource management, and disaster response planning. They can also be used to create 3D visualizations of landscapes and terrain.
