This AHN4 LiDAR point cloud tile (25GN1 18) provides high-accuracy airborne elevation data for professional geospatial site analysis. The AHN4 LiDAR dataset represents the fourth iteration of the Dutch national elevation survey, captured via airborne laser scanning. This specific file, identified as tile 25GN1 18, contains raw point cloud data formatted for integration into GIS and BIM workflows. It provides precise elevation values for terrain and surface features, capturing the physical landscape with high density. The data is structured to allow for accurate digital elevation model (DEM) generation and ground surface profiling. As a standard extraction from the national survey, the file offers consistent coordinate referencing and reliable vertical accuracy for large-scale environmental and urban modelling projects.

The download is a 73.9 MB file containing .LAZ files.

Professionals can import this LAZ file into industry-standard GIS software, such as QGIS or ArcGIS, or BIM platforms that support point cloud processing. Users should ensure their project coordinate system is correctly defined to align the point cloud with existing site plans and CAD geometry for accurate spatial analysis and site planning.

This dataset is essential for architects, urban planners, and civil engineers working on projects across the Netherlands. It serves as a foundational layer for site feasibility studies, drainage analysis, and large-scale masterplanning where accurate topography is required. Professionals often use this data in the early stages of design to establish existing site conditions and inform landscape development. It is frequently paired with aerial imagery and vector mapping to provide a comprehensive digital twin of the site, supporting precise volumetric calculations and environmental assessment tasks.
