Ciao Christian,
we never added support for gdal geotiff deiver since we always been using
our own which as comprabale performance and is pure java.
Therefore Would recommend sticking with the geotools geotiff reader that
should support bigtiff since the the move to imageio-ext 1.1
As of the pyramid thing, it is perfectly legal to have 1 single file for
each level since we treat it as a single mosaico anyway. Be aware that if
the size of the entier dataset we aer talking about is not too big you can
use a single mosaic with a few geotiff or bigtiff with inner ovrviews.
Moreover do not forget to retile the original tiff files.
That said we have do e some additional improvements lately to the
imagemosaic and pyramid for performance reasons which have not been
committed yet. We will do that shortly and let you know so that you can
test them and keep us posted.
Ciao,
Simone.
