TrailRunner

I am happy to announce that I finally got the GeoServer of Nordrhein-Westfalen integrated as a download source. This will open up a very detailed map coverage for the state in Germany with the highest population. To achieve this, I integrated a great package named proj.4 which is simply a framework to transform coordinate systems from one to another. In this case TrailRunner requires the WGS84 Spatial Reference System EPSG:4326 but the WMS Server of NRW only understands the Gauß-Krüger Reference System EPSG:31466, which is very common in Europe. But even though I can transform points from one coordinate system to another, I still have to rotate each map tile I get back from the server. Mostly by 1.06 degrees. And additionally I have to stretch and bulge the tiles horizontally and vertically to get a perfect overlay with the tiles in the neighborhood. Somehow I have the impression that the WMS server does something weird internally and this is the reason why they are unable to provide the EPSG:4326 projection by default. If someone of my honored readers has any deeper knowledge about what could be going on here, please drop me a line. I would be very thankful to discuss this topic and to find an appropriate solution. The quality, the server can deliver, is really worth the effort.
