Hi all,
I'm using the imagemosaicer to mosaic tiles together with different crs. In
this example I'm combining EPSG:32631 and EPSG:32630. Al the tiles are
having pyramides. On some zoom levels, it is having a gap like some tiles
are completely skipped. I have no clue why. Is this a known issue?
2 screenshot are attached. The same area, on 2 different zoomlevels.

Hi Bart,
is any log available reporting something when these gaps occur?
Do you have a gdalinfo output of the data involved in that missing piece?

Daniele,

I did the same test with files without overviews but the problem remains the same.

Attached you can find the log of requests for 1 zoomlevel. When zooming further in, the images are rendered well. The logfile is from the test without overviews where the gap is visible.

Also gdalinfo of all the files is attached.
