Overview
The AHN is a collaboration between Dutch provinces and water boards to maintain a high-resolution elevation model of the entire Netherlands. Generated from airborne LiDAR scanning, the AHN provides both a Digital Terrain Model (DTM) and Digital Surface Model (DSM). The current version (AHN4) has an average point density of 8 points per square meter. This data is essential for flood risk assessment, water management, solar potential analysis, and 3D city modeling. The AHN is available as open data through PDOK.
