Re: [udig-users] Reprojection WGS84 (4326) -> WGS84 Mercator / Google 
Hi Jody,
here my settings:

uDig 1.2RC-3 running on WinXP
Shapefile: http://www.gadm.org/data/gadm_v1_lev0_shp.zip from http://www.gadm.org/world
Dropping this shapefile in the empty map opens it with "GCS_WGS_1984" (without EPSG code) [1]. It is possible to switch to WGS 84 (4326) (standard WGS84).
But trying to set the CRS to WGS84 Google Mercator (900913) or WGS84 Simple Mercator (41001) or (54004) ends in this status bar message:
"Exception(s) occured during rendering: The coordinate reference system must be the same for all objects." [2]
There are two other exceptions in the logfile before. I don't know if they are related: [3] and [4].

We do update the EPSG database from release to release. What code were you using the the google projection? (It does have an offical code - which I cannot remember right now). I am not sure what to make of the error message; are your geometries changing projection within a single layer?

Perhaps a little more information on where your data is coming from and what you are trying to do with it? In general uDig reprojects all layers to match the map.

Hi all,

I'm using the GADM level 0 world dataset (EPSG 4326). 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.

Any ideas how to get this reprojection?

Thanks
Matthias
