[udig-devel] World Mercator with postgis

[David Zwarg <dzwarg@xxxxxxxxxxx>]

Hello,

I am wondering if there is a way to use the World Mercator projection in PostGIS in uDig.  I am unable to use either the PostGIS (3395) or the uDig (41001) EPSG codes for world mercator in my PostGIS layer -- they both show up as Generic cartesian 2D.  As soon as I attempt to add geometry and edit geometry, uDig goes into an endless loop of IllegalArgumentExceptions.

However, if I use an EPSG code that appears in BOTH postgis and uDig, it seems to work alright.  If there was a way to represent Generic cartesian coordinates in PostGIS, that would be preferable, but -1 causes this same IllegalArgumentException spiral.  Am I missing a general projection that would be more suitable?

Also, during this experiment, I was unable to create a custom CRS in the uDig map preferences, or by clicking on the button in the status bar.  How do you create a custom CRS from a known WKT?

Thanks,
David
