The University of Namur’s library has some wonderful building, local, regional and national maps on their NEPTUN site. They provide a Google Map like pan and zoom functionality using a commercial Flash program called Zoomify. It’s unfortunate they chose to pay for functionality that’s freely available from OpenLayers or Leaflet. Regardless of this the data is not downloadable as a large file. I do not see why data such as this is not made easily and freely available. As a University it seems that it should be encouraging the sharing of past knowledge. In order to help them, and because a colleague asked me for a map, I have created a script that downloads all the tiles and reorganize them into one image.
The script and instructions are on github. Get Poseidon on github
I created another script to get tiles from other providers - this one requires a bit more work to use though and I’ve moved on to other things. Check out PosMos on github
