[OpenLayers-Users] WMS, Google Map, and Vector Layer

[Chris Garstin]

Hi Arnd,


Thanks again for all your help.  To get around the problem with the one WMS
layer not supporting the projection that I need to tranform to for Google,
I've added some buttons to my map to swtich between Google and WMS layers.

Feel free to have a look.

You help is greatly appreciated.

Regards
Chris
