[postgis-users] Custom Projection

[Birgit Laggner]

Hallo Sean,

I tested it myself and this is because of the export function you are 
using. If I am using pgsql2shp, this results in the following prj:

GEOGCS["Geographic Coordinate System",DATUM["WGS84",SPHEROID["WGS 
84",6378137,298.257223560493,AUTHORITY["Custom","0"]],AUTHORITY["Custom","0"]],PRIMEM["Greenwich",0,AUTHORITY["Custom","0"]],UNIT["degree",0.0174532925199433,AUTHORITY["Custom","0"]],AUTHORITY[""Custom","0"]]

And this would be exactly as you want (the custom authority entries you 
may spare probably...). I don't know, if there is a way to tell QGIS to 
export exactly the coordinate system from the data origin.

Regards,

Birgit.
