I use the ImageMosaicJDBC plugin to connect to an Oracle raster table. Maybe
someone can clarify some things about the interpolation settings. There are
multiple locations where I can define the interpolation which is confusing
to me:
.) gdal_translate
gdal_translate -of georaster...
co GENPYRAMID=BILINEAR ^
okay this one is for the pyramid generation
.) .xml file for ImageMosaicJDBC
scaleop interpolation="2"
.) GeoServer Layer setting
Default interpolation setting=xx
The problem I have: I get a black/grey scaled border (screenshot) around my
raster layer when I open it via WMS and I used the setting scaleop
interpolation="2" or"3" in my ImageMosaicJDBC xml (with 1-NN it would work).
Creating a layer with the same GeoTIFF, but from the file system instead of
ImageMosaicJDBC it works like expected.

Btw. I don't understand how that .xml file of ImageMosaicJDBC works. Is it
only accessed once when I create a new data store? Or is it accessed every
time the layer is accessed?
Thanks for any clarification about that.
