This AHN5 LiDAR point cloud tile (25DZ1 18) provides high-accuracy airborne elevation data for the Netherlands in LAZ format. Representing a specific sub-tile of the fifth national elevation survey (AHN5), this dataset contains dense spatial information captured via airborne LiDAR. The file provides precise elevation points across the defined 25DZ1 18 coverage area. As a foundational geospatial asset, it captures ground levels, vegetation, and built structures with high resolution, enabling detailed surface analysis and terrain modelling. The data structure is optimised for large-scale geographic information systems, offering a reliable reference for topography and urban planning professionals requiring up-to-date, national-standard elevation metrics for the Dutch region.

The download is a 68.6 MB file containing .LAZ files.

Professionals integrate this LAZ file into GIS software or point-cloud processing engines such as CloudCompare, QGIS, or ArcGIS. Users typically import the tile to perform classification, ground extraction, or cross-epoch change detection by comparing it against previous AHN survey generations. The file serves as a base for generating digital terrain models (DTM) or digital surface models (DSM), allowing for accurate volumetric calculations and site analysis within professional surveying and civil engineering workflows.

This dataset is essential for large-scale infrastructure projects, urban masterplanning, and environmental monitoring across the Netherlands. It is frequently utilised in site feasibility studies, flood risk assessments, and heritage conservation efforts where precise topography is critical. Architects and civil engineers use these files to establish accurate site contexts, ensuring that new developments align with existing ground levels and local landscape characteristics. It is a standard resource for professionals working within the Dutch AEC sector for rigorous spatial data analysis.
