Re: [Geotools-gt2-users] follow-up on raster question

[Michael B. <mic...@gm...>]

HI Nick,

Yep, this would certainly be nice.  But if by the "community" you mean
the active developers the main problem is that it is just a handful of
people, most (all ?) of whom are already over-committed.  This is the
bottleneck for many good ideas.

Meanwhile, if you need something like this right away and you don't
mind getting some JAI dirt on your hands, you might want to look at
some of the operators in the jai-tools project which can be applied to
the image backing a GridCoverage2D...

http://code.google.com/p/jai-tools/

(disclosure: most of the code there is my fault)

There was an effort started by Simone and Daniele to bring jai-tools
functions into GeoTools (see the unsupported/jai-tools module in svn).
So far it looks like only the ZonalStats operator has been included
and I don't know if the effort is active.

Perhaps you can help ?

Michael

PS. out of interest, is RAMAS using GeoTools ?
