                 Key: GEOS-3883
                 URL: http://jira.codehaus.org/browse/GEOS-3883
             Project: GeoServer
          Issue Type: Bug
          Components: WMS
    Affects Versions: 2.0.1
         Environment: Windows Jetty, Windows Vista64, Java 1.6, GDAL, JAI, JAI-ImageIO
            Reporter: Nicholas Spragg
            Assignee: Andrea Aime
         Attachments: original.zip, result.zip

The image produced from GeoServer does not match the original.

A subset(using BBox) was requested of a Image stored in GeoServer. The Original image is in UTM and the reprojected result from GeoServer is in Geographic.

It appears that GeoServer is applying a reproject for each tile block. The result is that each tile block is slightly warped causing irregular distortions across the image(See Attached).
