Thank you for the clarification Andrea. It seems the capability would be
useful. Do you have a reference where I could learn more about the custom
programmed index? I would like to consider that approach before deciding what
to do next. We have a lot of imagery and will need to decide an approach to
despeckle them without processing them. So far, I only see two straightforward
approaches, bringing back the footprint functionality, or if possible
attempting some change so that a nodata value range can be used in the
imagemosaic plugin so a list of values could be used.
Thanks again,
Shamus

Hi, I have seen several references to a working technique to use a
footprint.shp file with the imagemosaic plugin to despeckle compressed images.
I have not yet however seen any reference to how exactly to do it. I would
appreciate someone pointing me to the appropriate documentation or explicitly
describing the procedure. I've found no documentation of a procedure anywhere.
I've looked at some code, hoping to derive a procedure, but nothing we've tried
so far works.
The footprint management via shapefiles has been lost along the way, it was
present in an old
branch but not forward ported.
Nowadays the mosaic code has the machinery to deal with footprints when used
programmatically
with a custom programmed index, but cannot read footprints from shapefiles and
cannot be configured to do so
With some work the functionality could be brought back, and this time,
committed to trunk first, so that
it stays there for the foreseeable future (the old changes cannot just be
ported, the mosaic code base
has changed a lot since back then).
Cheers
Andrea
