This AHN4 LiDAR point cloud tile 25DZ2 18 provides high-precision airborne survey data for the Dutch national elevation network. The AHN4 dataset represents the fourth iteration of the national elevation survey of the Netherlands, captured via airborne LiDAR technology. This specific tile, 25DZ2 18, contains dense, georeferenced point cloud information that captures ground topography, urban infrastructure, and vegetation cover. The data is provided in the industry-standard LAZ format, ensuring efficient storage while maintaining high spatial resolution. As a raw survey product, it offers an accurate digital representation of the physical environment, suitable for rigorous analysis, site planning, and terrain modelling within geographic information systems or specialized point cloud processing software packages.

The download is a 44.1 MB file containing .LAZ files.

Professionals integrate this LAZ file into GIS software or BIM platforms to perform terrain analysis, site context generation, or massing studies. Users should import the tile into a coordinate-aware environment to ensure accurate spatial alignment with existing project data. Once loaded, the point cloud can be filtered, classified, or converted into a digital terrain model (DTM) or surface mesh to serve as the foundation for site design or urban planning workflows within a larger project scope.

This dataset is essential for urban planners, civil engineers, and landscape architects working on projects situated within the Netherlands. It provides the necessary base information for site feasibility studies, drainage analysis, and large-scale master planning in both rural and metropolitan contexts. By utilizing this accurate elevation data, designers can ensure their proposals respect the existing topography and urban fabric. It serves as a reliable starting point for any development project requiring precise ground-level context or accurate volumetric assessments of the surrounding environment.
