2010-05-21 Thread Chris Nicholas
greetings - first and foremost, as usual, I was pleasantly surprised to find more neat stuff when I went looking for it in GDAL. :-) I'm trying to use this newfangled spherical mercator projection, EPSG:3857, with Mapnik, but want to manage all the raster foo in good old mapserver, with a TINDE
