An Elevation Model is a digital representation of the Earth's surface that shows the height of terrain features above a reference point, usually sea level. These models are created using various data sources, including satellite imagery and ground surveys, to provide accurate topographical information. They are essential for applications in geography, urban planning, and environmental studies. Elevation models can be visualized in different formats, such as Digital Elevation Models (DEMs) or 3D terrain maps. They help in understanding landforms, analyzing watershed areas, and planning infrastructure projects. By using elevation data, researchers and planners can make informed decisions about land use and resource management.
