A tutorial for postgres is here http://docs.geoserver.org/stable/en/user/tutorials/imagemosaic-jdbc/imagemosaic-jdbc_tutorial.html I would like to recommend you this one http://trac.osgeo.org/postgis/wiki/WKTRaster but due to lack of time there is no support in the imagemosaicJDBC module for the moment. > Rob Cheers Christian > > > > ________________________________ > Von: "[email protected]" <[email protected]> > An: Robert Buckley <[email protected]> > Gesendet: Mittwoch, den 20.
