Re: [Geotools-devel] Hue Rotate for Rasters

[John Schulz]

Simone,
I've gone with the approach to right now implement this as a rendering
transformation.  I took this approach because it is less invasive than the
other approaches and the operation can easily used as a raster process and
SLD.  Let me know if you have any concerns.

Thanks,

John Schulz

Access to the new build server for geogig / geofence teams

GeoGig and GeoFence teams would like access, this server is run by
GeoServer PSC.

Note: GeoGig relies on ares to build “non clean ip” stuff like OSM
integration, that due to license is not welcome on eclipse infrastructure.

How do we want to manage server permissions? Normal motion, just like
adding a committer.

Action: Erik Merkle: Request build.geoserver.org access on email list to
manage geogig community builds
