sorry, forgot to "reply all"<br>here's my response:<br><br>great that totally worked. I'm going to send a request to Manifold GIS
to officially add that projection. For the moment, my data (which is in
the world mercator) is near its correct position, as long as you're not
zoomed way out. thanks for your help!!!<br><br>PS. Manifold GIS doesnt use proj.4, but you can add projections from WKT, I'll play around with that-<br><br><br><br><div class="gmail_quote">On Sun, Nov 16, 2008 at 7:44 PM, Dane Springmeyer <span dir="ltr"><<a href="mailto:blake@hailmail.net">blake@hailmail.net</a>></span> wrote:<br>

<div class="Wj3C7c">Hi,<br> I've got the TileCache TSM service working (thanks to the list for tips!), but unfortunately, my WMS does not support the "Spherical Mercator" projection. 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>
