For the moment, i rewrote the wms service to switch up the espg and coordinates from tilecaches's tsm request and converting them to lat/lng, so that at least the WMS request will go through, but I assume a standard mercator projection to do the conversion (which is obviously wrong). Since my GIS/WMS doesn't support this projection, does anyone have the necessary code to convert coordinates from the spherical mercator to lat/lng? <br> Thanks!<br clear="all"><br>-- <br><br>Chris Marx<br>Programmer/Analyst<br>Cornell Lab of Ornithology<br>159 Sapsucker Woods Rd.<br>Ithaca, NY 14850<br>t. 1.607.254.1142<br><a href="http://www.birds.cornell.edu/">http://www.birds.cornell.edu/</a><br> _______________________________________________<br>Tilecache mailing list<br>Tilecache@openlayers.org<br>http://openlayers.org/mailman/listinfo/tilecache<br></blockquote></div><br></div></div></body></html>
