Hi, before we cut GeoServer 2.20.x I'd like to add all common tile matrix set definitions to GWC, as taken from the OGC Tile Matrix Set (TMS!) specification <http://docs.opengeospatial.org/is/17-083r2/17-083r2.html>.
They are named, in order: - WebMercatorQuad - WorldCRS84Quad - WorldMercatorWGS84Quad - UTM##WGS84Quad - UPSArcticWGS84Quad - UPSAntarcticWGS84Quad - EuropeanETRS89_LAEAQuad - CanadianNAD83_LCC Per se this change only adds a bunch of new gridset to DefaultGridsets <https://github.com/GeoWebCache/geowebcache/blob/main/geowebcache/core/src/main/java/org/geowebcache/config/DefaultGridsets.java>, making it easier to set up a GeoServer that is better aligned with standards. it would add quite a bit of well-known gridsets to GWC... which would make the WMTS capabilities document bigger. Maybe it's best if the WMTS capabilities generator only outputs the gridsets that are actually used. This would also allow to follow suit with previous changes, and add to each a 512px tile version, that has a "_x2" suffix. In terms of redundancy, the WorldCRS84Quad has a different number of zoom levels compared to EPSG:4326, while WebMercatorQuad scale denominators are slightly different than the ones in EPSG:900913 (first decimal is different at zoom level 0) and the number of zoom levels is again different... so neither would be an equivalent, these would be new grid sets. Perhaps it would be a also good idea to have new Geoserver data-dir default to use WorldCRS84Quad and WebMercatorQuad by default? Though it might cause troubles with set ups that spin up a GeoServer from docker images, and expect to find the usual defaults instead.... ideas here? Maybe GeoNode would be affected?
