Point cloud

The aerial photograph closest to the acquisition date of the AHN iteration was overlaid on the point cloud to produce a colored version for visualisation purposes. Furthermore, for each point cloud a spatial index and textual summary, including elevation histogram, are provided. Please note that the images are not from the same flight, and may be years off. Therefore, small alignment errors and differences occur between them.

Zoom in on the map to see tiled versions (25 tiles of 1×1.25 km). Tiled versions typically fit into memory (RAM) are easier to handle and are especially suitable for parallel processing and Machine Learning.

Point cloud

These sub-tiles of 1×1.25 km are clipped from the original point cloud. Goal is to enable distributed processing of the point cloud. Therefore, a 25 m overlap to the neighbouring (sub-)tiles is added. Thanks to the overlap between sub-tiles, the sub-tiles can be processed independently and therefore parallel.

All other data sets on this website are only available in the main tiling schema.
