Hi,
I am looking into dynamic color maps
<http://docs.geoserver.org/stable/en/user/community/colormap/index.html>
these days for the ncwms integration (since it's really the same
problem with different syntax).
The current module offers a fiilter function providing a PAMDataset if
available, which originates from
a GDAL statistics file (a .aux.xml one) if available.
For my work I want to use something easier to control for the admin as the
default value for the min/max
ranges, and in particular the ones configured band by band in the geoserver
layer panel (min/max range),
so that people can edit them without having to drop on the command line:
[image: Inline image 1]
Now, that normally comes with the full range of the datatype (we do not run
stats on coverage creation),
but if the GDAL stats are already there, I want to use it instead to
populate the min/max range.
Of course it would also be nice to have a button to compute it on the fly
from the data itself but...
against a large mosaic that would take hours. Implementing this would go
beyond the time I have
available (pity).
Anyways, any objection to using the GDAL stats when they are available?
Cheers
Andrea
