[OpenLayers-Users] Retrieving different coordinates

[Bart van den Eijnden (OSGIS)]

I have no experience with this code, but can confirm this is the way to go.

AFAIK this will probably make it into OpenLayers 2.6, so maybe it's still a
bit too early to attempt this (depending on your javascript skills
ofcourse).

Maybe someone else can give you more pointers.

Best regards,
Bart
