Yep, exactly this bug happens here.
An Oracle Georaster Object is basically a BLOB with extra features
- georeferencing
- inner tiling
- pyramids
You can compare such an object with a geotff file.
This proposal has the following architecture.
- You have a big base image.
- Generate the tiles fo

Within the new extended border, I need the pixels from the neighbor tiles.
Normally, if I have a big image,
I create the pyramids and finally create the tiles for all levels.
If I create the the tiles first and the pyramids for each tile
individually, it is possi
Ciao Christian,
andrea is right, the trick is to use a border extender of appropriate
size which simply
copies the border pixels over and over within the limits of the
appropriate size of course
which depends on the padding required by the interpolation, 1, 2 ,4
etc. etc. (see the interpolation cla

Ahh I remember, you build the pyramids for each tile separately. I hope you are
aware of the fact that this does not work for each map. I had
help, guidance and advice would be welcome.

Sure, sounds great :-)
I'd just double check the copyright assignment thing, I don't think

Hi Jody,
Last year I extended Christian's imagemosaic-jdbc module to support Oracle
Georaster. This however, was quite a dirty implementations and had a
dependency on about 11 external Oracle java libraries (which, is not workable
in the opensource world!).
The imagemosiac-jdbc module was the
