[mapserver-users] doubt about mapserver URL: coordinate system

[Sebastian E. Ovide]

Hi List

I'm using OpenLayers + MapServer. With Firebug I see that OpenLayers calls
MapServer with ULRs like this:

http://mapserver/mapserver?layers=NAFRA_2008_final
map=/home/gis/conf/mapserver/uk.map
mode=map
map_imagetype=png
mapext=-374388.56527373+7296678.7179959+-374312.12824546+7296755.1550241
imgext=-374388.56527373+7296678.7179959+-374312.12824546+7296755.1550241
map_size=256+256
imgx=128
imgy=128
imgxy=256+256

Just trying to understand the coordinate system used by mapext and imgext. (
it is different from than that used to call Google servers:
http://mt0.google.com/vt/lyrs=m@133&hl=en&src=api&x=257246&y=166679&z=19&s=G
)

Is it possible to use a different coordinate system ? say for example the
same coordinate system specified in the LAYER (in my case epsg:27700)

thanks
