Digital Surface Model (DSM)

A Digital Surface Model (DSM) is a digital representation that shows the Earth's surface, including all objects on it like buildings, trees, and other structures. Unlike ground elevation models that only depict the bare earth, DSM captures the highest points at each location, providing a detailed view of the surface's features. This data is used in various applications such as urban planning, forestry, and environmental monitoring to analyze the physical environment and support decision-making. It is typically created using remote sensing technologies like aerial photography or LiDAR.
