GeoTools / GeoServer PMC meeting - 2023-05-23Attending -
Torben Barsballe - Jukka Rahkonen - Andrea Aime Actions from prior meetings: - [DONE] Andrea to ask for a 2.23.1 release volunteer Agenda 1. GS 2.23.1 release train 2. CSW/JDBCConfig contentious PR 3. Backporting URL checks GSIP 4. Planetary CRS GSIP progress 5. H2 removal, bit by bit Actions - TBD GS 2.23.1 release train Ian performed the releases, thank you! Looks like announcements are the missing bit. Release publish jobs are failing at rysnc: https://sourceforge.net/p/forge/site-support/24659/ We might want to try replicate the publish script in the job and see if that works by changing the rsync location (could ssh into the server and try rsync manually, not clear how to provide credentials though.. the release logs might contain some hints about usage of ssh-agent). CSW/JDBCConfig contentious PR https://github.com/geoserver/geoserver/pull/6841 Exposing CSW records of local layers against JDBCConfig is slow. Need other PSC members concerned with GeoServer architecture to chime into the discussion. Backporting URL checks GSIP https://github.com/geoserver/geoserver/wiki/GSIP-218 Landed on main. Discussion ongoing about backports to stable. Remote checks enabled by default or not? Torben: disabled by default, very clear message in the release notes that they should be updating. Too many people assume patch version updates are safe, it might make people stop updating in fear of production breakage. Jukka: +1 Planetary CRS GSIP progress Some changes landed in GeoTools, have a gt-iau-wkt authority: 2000 extra codes, it’s going to be a plugin. Can configure a shapefile and a geotiff and do map preview (that needs a GeoServer PR <https://github.com/geoserver/geoserver/pull/6833>, just getting it merged). https://github.com/geotools/geotools/blob/main/modules/plugin/iau-wkt/src/main/resources/org/geotools/referencing/iau/iau.properties Also added support for authority in property file datastore, which allows to write tests in GeoServer. Working now on capabilities document generation. GeoTools has no idea about the planet it’s dealing with , PROJ seems to have extended the database: data/sql/iau.sql:INSERT INTO ellipsoid VALUES('IAU_2015',49900,'Mars (2015) - Sphere',NULL,'IAU_2015',499,3396190.000000,'EPSG','9001',NULL,3396190.000000,0); but also: data/sql/esri.sql:INSERT INTO celestial_body VALUES('ESRI', 'Mars', 'Mars', 3393400.0); Using this proj denies reprojection between different planetary bodies, for example: > cs2cs "IAU:49900" "EPSG:4326" proj_create_operations: Source and target ellipsoid do not belong to the same celestial body >From proj.db semi_major_axis ESRI Atlas Atlas 16000.0 ESRI Helene Helene 16000.0 https://en.wikipedia.org/wiki/List_of_Solar_System_objects_by_size So no, we cannot just compare by diameter. Fun situation, OCG API Features mandates output in WGS84… what if your data is for Mars!! Example WKT2 for Jupiter and Mars: https://github.com/OSGeo/PROJ-CRS-Explorer/blob/master/wkt2/IAU_2015/59900.txt https://github.com/OSGeo/PROJ-CRS-Explorer/blob/master/wkt2/IAU_2015/49900.txt See also Mars prime meridian: https://mars.nasa.gov/gallery/atlas/PIA03207.html H2 removal, bit by bit Replacing GWC disk quota and KML superoverlay databases with HSQLDB. Enough to have GeoServer core free of H2 dependencies. Already used for EPSG database, works fine for non spatial database, does not support spatial. GWC pull request ready and GS incoming. This will also allow H2GIS to become an official extension (will be incompatible with some other extensions, but at least usable). In time we hope to upgrade other parts like NetCDF, GeoFence, WPS and importer async status storage.
