A change in Geoserver (or Geotools) core code introduced in versions 2.11.0 and 2.10.3 broke possibility to display (reproject) as an EPSG:900913 jpeg/png a GeoTIFF defined in the RotatedPole CRS. How to reproduce: Define a custom RotatedPole CRS: 100111=PROJCS["UM PL rotpole",GEOGCS["UM PL GeogCS", DATUM["World Geodetic System 1984",SPHEROID["WGS 84",6378137.0,298.257223563]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9108"]],AXIS["Longitude", EAST],AXIS["Latitude", NORTH]],PROJECTION["Rotated_Pole"],PARAMETER["central_meridian", 19.3],PARAMETER["latitude_of_origin", 52.5],PARAMETER["scale_factor", 1.0],PARAMETER["false_easting", 0.0],PARAMETER["false_northing", 0.0], UNIT["degree",1.0,AUTHORITY["EPSG","9108"]], AUTHORITY["EPSG","100111"]] Create a GeoTIFF store with attached file Publish it with SRS forced to EPSG:100111 (as defined above) using the “dem” palette Switch to “Tile layers” Try to preview in EPSG:900913 Resulting picture should be similar to the EPSG:4326 preview but looks like a highly over-zoomed part of the expected picture. However, clicking on the map itself return proper values. Please note that nothing has been changed in the RotatedPole code since the initial commit.
