I have GeoServer and OpenLayers running quite nicely and now need to overlay a CAD drawing. I have looked at the geographic location part of CAD and set the Long/Lat to the appropriate values. I saved the drawing and then converted to a shapefile and then imported it into PostGIS. When I add to GeoServer the native bounds and Long/Lat generated in GeoServer are nowhere near where I would expect them to be. Can anyone point out what I am doing wrong?
When I set the Long/Lat in my drawing where does this point reference? Is it the center, top and left, bottom and left of the drawing? Also how can I find out what projection the drawing is in. It doesn't seem that you can set this in CAD. I've asked my CAD guys and no one seems to know.
