Details

PDOK provides tiles that can be used as a tile layer in several geovisualization tools including leaflet. The layers differ from other tile layers such as Openstreetmap, Google and cartomap in the following manner:

  • The tiles are restricted to the Netherlands: tiles accross the Dutch border are "grayed out". This is useful for cartographic applications that are restricted to Dutch geo-information.

  • The tiles are open source and based on open sourced geo-information.
