[OpenLayers-Users] TMS Overlay on WMS

Curtis Jensen Tue, 09 Feb 2010 11:08:41 -0800

I'm trying to overlay a TMS on a WMS.  The TMS appears to be
configured for a specific max extend.  If I don't use that max extend
in my WMS, then the TMS overlays on top the entire world, instead of
the area it is suppose to.  Below is the WMS example that I've
modified to have an TMS overlay.  I can't get it to work without
having the max extends set.  However, I would like to have the whole
world shown and the TMS scaled and translated to the correct location.


Is this doable?

Thanks,
Curtis
