Hi,

We are trying to publish to GeoServer some older paletted tiff-images but have a strange problem - GeoServer returns a totally white image, no error messages (checked the logs).

First we tried with ImageMosaic, then also single images. Some of the single images were showing up normally, some are also white, although with gdalinfo I do not see any differences for these images and they are from same vendor from same delivery (example below).

The files are paletted geotiffes and are about 10 years old, but for example in QGIS they display without any problems. According to this post (http://osgeo-org.1560.x6.nabble.com/Publishing-GeoTiffs-ColorPalette-with-Alpha-td5128601.html), I could understand, that paletted geotiffs with alpha channel can not be published with GeoServer? But some of the images do show up??

  • I tried also changing the style, so that certain values would have certain color, but no change. The images showing up have the default raster style. . Clicking on the map preview does not give any results, could think that if for some reason whole image is just pained white, it still would give values for GetFeatureInfo request?

  • Tried also setting Coverage Band Details minRange and MaxRange, but no change. By default both were 0 for imagemosaic, but -indefinite to indefinite for single image.

  • The granule grid for ImageMosaic looks good. And the coordinates for Preview seem ok.

Hi,

The data is available here:

https://filesender.funet.fi/?vid=01ebcfb1-a5e0-9149-7a24-00000f6ba256

For example mapsheets 32_33op and 30_31mn are white, but 24_25op is ok.

Some test layers are visible here:

Hi,
made a quick test locally with a 2.8.x I had handy, checked it,
and indeed it’s white.

Then I’ve looked into its property config file of the mosaic and found this:
ExpandToRGB=false

Switched it to ExpandToRGB=true and reloaded the geoserver configuration,
and voilà, it works (well, almost, I still see some vertical black lines where
the tiles match up, not sure if it’s the data or some other issue).

Could you open a bug report at https://osgeo-org.atlassian.net/projects/GEOS,
it might be that we are wrongly detecting the palettes to be all the same,
or there might be some issue in the management of the paletted images
processing chain in the mosaic

Cheers
Andrea
