Re: [udig-users] Reprojection WGS84 (4326) -> WGS84 Mercator / Google
|
Thanks for the extra details; I think we need to handle them one at a time.

Okay so you are probably switching by right licking on the Layer and changing the layer properties. Other then that we may have to ask on the geotools list about the failures related to parsing the coordinate reference system.
The specific line that is producing the the exception seems to be in error (it is code that is trying to look and see when all the content is off screen and thus draw nothing). I am going to go start a discussion on the devel list about how to solve it.

To get it rendered with less vertical squeezing I'm trying to use standard mercator or google projection. uDig responds with an error message for the layer "The coordinate reference system must be the same for all objects". I'm running uDig 1.2-RC3 and IIRC this was possible in a former version.
