[Geoserver-users] srs 900913

All,

I'm running geoserver 1.6.4. I'm trying to output wms in srs 900913 (google
maps projection). I added the srs definition to spatial_ref_sys in postgis
and to the epsg.properties table in geoserver. But if I make a WMS request,
I don't get anything returned...no image, no error in the logs. Any
thoughts?

Thanks,
Steve

What’s your WMS request look like?

Hi Stephen,

You should not have to play with the postgis spatial_ref_sys table unless your data is actually in the google maps projection. As well 900913 should be already included in the epsg.properties file as well.

All you should have to do is issue the request with the parameter "SRS=EPSG:900913" and also ensure the "BBOX" parameter is in the 900913 projection.

If you are seeing a blank image it more often then not means that your postgis table does not have the correct projection set on it, or you are issuing the request in incorrect coordinates. What is the native projection of your data?

Hi Justin,

I was making a bone-head mistake in sending the bbox in lon-lat instead of
meters....it's all good. Thanks for for the help.
