I see some inconsistency (a bug?) in a way Geoserver handles GeoTIFF
files with custom coordinate reference system.

In case you import attached file directly as a GeoTIFF:

  • it is correctly displayed in the Google Earth (as a kml file)
  • Layer Preview in Geoserver shows empty image

If you import it as ImageMosaic layer (indexer.xml file attached):

  • it is displayed upside down, both in the Layer Preview and the Google Earth

Differences starts from coverage.xml files: “scaleY” parameters have
opposite sign, “translateY” value is different. I noticed also that
org.geotools.gce.imagemosaic applies additional (unnecessary?) affine transform before
displaying the image.

GeoTIFFs with other custom CRS have similar problems, so I think it’s
more general issue.

CRS definition:
