Hello all,
We recently upgraded from GeoServer 2.3.5 to version 2.5.0 and are experiencing
some issues with our ImageMosaic layers. Previously, the data was exposed as
PALETTE_INDEX values which allowed us to style the data on the fly using custom
SLDs. After upgrading, however, GeoServer identifies this data as RGBA which
prevents our custom styling. The coverageDimension is defined as a
PALETTE_INDEX, but GeoServer appears to ignore this. Is there any way to force
the PALETTE_INDEX on the existing data or do we need to re-encode the rasters
somehow?
The rasters are stored as single band 8-bit png files. Here is a snippet from
the gdalinfo:
Coordinate System is `'
Corner Coordinates:
Upper Left ( 0.0, 0.0)
Lower Left ( 0.0, 2859.0)
Upper Right ( 4944.0, 0.0)
Lower Right ( 4944.0, 2859.0)
Center ( 2472.0, 1429.5)
Band 1 Block=4944x1 Type=Byte, ColorInterp=Palette
NoData Value=0
Color Table (RGB with 256 entries)
0: 0,0,0,0
1: 0,240,240,255
2: 0,144,144,255
...
Any help would be appreciated.
Thanks,
