Yes, this is a problem. The reprojection support is relaly about 'from the data projection to the baselayer projection'; the baselayer being what actually controls the projection of the map. See: http://crschmidt.net/mapping/choropleth-mercator.html For an example of using a 'fake' baseLayer with a mercator projection, and reprojecting to it in the standard ay, as another solution. -- Chris > I have two examples up on our server > > http://webmapping.critchlow.co.nz/working/googlelayer.html > > http://webmapping.critchlow.co.nz/working/nogoogle.html > > > With the 'googlelayer' link I have a second base layer that is straight > KML(labeled CoverageTEST) and the country comes up fine and looks how it > should. - only problem is that I only want the KML as the base map and want > to remove Google all together. - if I do this I get the 'nogoogle' layer. > > With the nogoogle layer - this is the aim.
