A projection handler is a class used in "advanced projection handling" that knows about the projection valid area (from a math point of view) and is used to cut geometries before reprojecting them. In this case it's used to cut away imprecise geometries/rasters that have even the slighties bit outside of the -180,-90,180,90 range, which would make the projection fail. All in all, the news is that we have now a better chance of reprojecting a layer touching the poles and the dateline with the Van Der Grinten projection, but the projection itself was already there, has been there since 2011 acconding to GitHub history: https://github.com/geotools/geotools/commits/master/modules/library/referencing/src/main/java/org/geotools/referencing/operation/projection/WorldVanDerGrintenI.java Cheers Andrea -- == GeoServer Professional Services from the experts!
