Digital Surface Model (DSM)

Capture Everything.
Model the Surface.

Digital Surface Models (DSMs) represent the elevation of the Earth's surface, including all natural and man-made objects such as buildings, trees, and infrastructure. DSMs provide a complete 3D view of the landscape for advanced analysis and visualization.

Overview

What is a Digital Surface Model (DSM)?

A DSM represents the elevation of the Earth's surface by including both natural terrain and all man-made and vegetation features. It is generated from the first returns of LiDAR point clouds and is widely used for urban planning, infrastructure design, visibility analysis, flood modeling, and more.
