(I suppose this is akin to map licenses often considering the copyright as a right to reproduce the picture (and wasting paper "you can print...") and not the right to make measurements on it. On the other hand, Minister Henry ordered the SPW to free their geographic data.
The PICC story is a pity. In 2010, I notified the SPW helpdesk that the PICC server was returning blank tiles in EPSG:4326 which is practically a requirement for JOSM and which is served by almost all servers in the world. No answer. Later on, I asked to feed this request through our official channel with the SPW and my insistence was laughed at by Julien Fastré whose own insistence was "we cannot copy yet". Now, that bug has finally been fixed. In short, if the SPW had fixed that bug when I reported it, we would have enjoyed a 5-year JOSM tagging at a 20 cm precision since what we do is not copy. I was able to use the PICC with Mapproxy, I did not because of the false instructions but yet I have been suspected to be a copying pirate! And nowadays, it's a real pity to find most houses and roads at a 2 to 5 m distance of their real location, especially those who were and still are mapped with other tools than JOSM and PICC. It makes feel like everything has to be redone again at 20 cm precision.. Making corrections is difficult because I proposed a revision date tagging that could have been very useful in this case but there was no interest on the Tagging list and even Marc Gemis was on my tracks to say it's impossible. In consequence, if you find the following tag, it means that I have rectified the geometry. source=20cm-near PICC http://geoportail.wallonie.be 2015 or source:geometry=same. Unfortunately, I have made many many untagged corrections.
