thanks Carla, although I'm not sure about that last bit. So I have searched for the epsg parameters of 31300 (Belge Lambert 72), and now I have to add some parameters ? I'm not sure which parameters I have to add/adjust..
<31300> +proj=lcc +lat_1=49.83333333333334 +lat_2=51.16666666666666 +lat_0=90 +lon_0=4.356939722222222 +x_0=150000.01256 +y_0=5400088.4378 +ellps=intl +units=m +no_defs no_defs <> Thanks Steven On Wed, Apr 9, 2008 at 9:04 AM, cfb <[EMAIL PROTECTED]> wrote: > > Hi Steven, > > I had the same problems, my data were in EPSG:23030 but when I wanted to > overlay my WMS in Google Earth, even If I'd included EPSG:4326 in the > wms_srs list, It showed a difference between my map and Google.
