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,
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), I could understand, that paletted geotiffs with alpha channel can not be
published with GeoServer?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.
* GeoServer version 2.7.1
