In a country like Netherlands, where about half of its land is less than 1 meter (3.3 ft) above sea level, having detailed and precise elevation data is vital for applications like flood management, climate change, 3D visualization and terrain analysis. We are excited to include highly detailed 3m elevation data for Netherlands derived from AHN2 LiDAR point cloud into the Esri World Elevation Layers. The LiDAR data came from Rijkswaterstaat, Provincies en de Waterschappen and consists of 1374 LAZ files of approximately 0.5 terabytes. Esri Netherlands processed the data after fixing the anomalies and quality issues and contributed the DTM’s of the entire Netherlands to the Living Atlas of the World. With this update, Netherlands has a whopping 30 times more detail.
The AHN2 dataset greatly enhances the world elevation layers and its derivatives. We will continue to improve these layers with the best authoritative data available from public sources and community contributors.
