Just out of curiousity, what is the native projection of the rasters, lat/lon? Taking lat/lon rasters into a polar projection can cause some singularity cases (interesting thread on that recently on mapserver-users) which means the projection code needs to be more "robust" as you put it. We rely directly on the geotools raster re- projection code, so we will see what the geotools developers know about these issues.

Hello--

Sorry if this information is available somewhere, I've been looking all morning and wasn't able to find an answer to my question.

I am curious the state of raster support with projections other than WGS84. I have been experimenting with UPS North (polar stereographic) projection and various raster sources with the following results:

1. Simple shapefiles with projection files (prj) appear to be properly reprojected or displayed natively on UPS North (EPSG: 32661). 2. I can get a tiff worldfile image to appear on UPS North, but it is not very accurate. It has been scaled, but not rotated or stretched properly. 3. Using a WMS server, no reprojection occurs. I get errors such as "Error: Bad Ordinates at dimension 1"

Is there any plan to add more robust raster support? Is there som e raster format that will display accurately in other projections (geotiff or something else?).

Thanks.
