Re: Mercator projection in Geoserver

Mmmm. It doesn't work. Distorsion continues. (http://www.wfisjamboree2007.org/)

I'm using these files:
http://www.wfisjamboree2007.org/sites/default/wms236.js
http://www.wfisjamboree2007.org/sites/default/wfisjam2007gmap.js

Javier, what "myMercZoomLevel" value are you using in your custom tile?

Now the point is to find the proper EPSG code. Jhon says that he get good
results with that code + Mapserver. Why it looks different in Geoserver?

Once we find the magic number, jhon can modify his wms236.js script.
