[Geoserver-users] Coordinate system problem.

Hi,

I created an image pyramid which was in EPSG:4326 ie wgs84 using gdal_retile

When I loaded it into geoserver it was accepted and displayed without a problem. however, the coordinates are not in lat/lon they are…(see bbox)

geoserver/wms?service=WMS
&version=1.1.0
&request=GetMap
&layers=zgb:tk50
&styles=
&bbox=976647.122,6686234.936,1369814.506,6934459.818
&width=522&height=330
&srs=EPSG:4326
&format=application/openlayers

Geoserver reports the native coords as EPSG:4326 but this can´t be correct, can it?

When I look at the original Geotiff on my desktop it is displayed in lat/lon.

This is obviously a missunderstanding on my part, but what is going on?

thanks for the tips,

Robert

hi,

I’ll answer the question mayself…I changed projection: epsg900913 to projection: epsg4326 and it was displayed ok.

Does this mean that I can´t display my own epsg: base maps together with google maps?

thanks,

RObert

You can display any layer you like over Google Maps however as Google
invented their own projection and don't allow reprojection of their
tiles you must make the request using their projection (900913) as you
have found out.
