Introduction

What is a Digital Elevation Model (DEM)?

A DEM is a 3D raster representation of terrain elevation above a datum. LiDAR-derived DEMs capture the bare-earth surface by removing vegetation, buildings, and other objects, delivering highly accurate elevation data.

Represent

Earth's surface elevation in a digital raster format.

Derived From

LiDAR point clouds using advanced classification.

Used For

Analysis, modeling, planning, and visualization.

Supports Better

Decisions with accurate terrain information.
