[Geomoose-users] xyz layers - UTM projection

Mark,

   I think [Google] XYZ use Spherical Mercator by definition.  To use a 
different coordinate system, you'll need to use TMS tiling.  As I 
recall, in my early experiments, I:
     - used MapTiler to tile my image
     - added a bit of JavaScript to GeoMoose to allow for a map-source 
type of "TMS"
     - added JavaScript (generated by MapTiler) to convert projected 
coords to tile ulrs.

How did you create your tiles?

Best Regards,
Brent Fraser
