Digital Surface Model

A Digital Surface Model (DSM) is a 3D representation of the Earth's surface that includes all visible features, such as trees, buildings, and hills. Unlike a Digital Elevation Model (DEM), which shows only the bare ground, a DSM captures the height of everything above it. These models are created using data from sources like satellite imagery and aerial surveys. They are used in various fields, including urban planning, environmental studies, and disaster management, helping professionals analyze landscapes and make informed decisions based on the elevation and contours of the terrain and structures present.
