[gdal-dev] GDAL Maintainers Meeting Minutes

[Howard Butler]

Howard Butler, Dan Baston, Alessandro Pasotti, Norman Barker, Daniel Morissette, Kurt Schwehr, Jukka Rahkonen, Michael Sumner, and Javier Jimenez Shaw held the monthly GDAL Maintainers Meeting on 02/27/2025. The following items were discussed and reported upon:

Project News
----------------------------

* Even engaged two potential part-time (~ half a day / week each) documentation maintainers who are enthusiastic to be supported by the GDAL Sponsorship Program to improve documentation needs highlighted by last fall's GDAL User Survey. A GDAL PSC member is needed to engage with and commit to managing them to continue moving it forward.
* GDAL 3.10.2 "Gulf of Mexico"  was released https://github.com/OSGeo/gdal/blob/v3.10.2/NEWS.md
* libgeotiff 1.7.4 was released https://github.com/OSGeo/libgeotiff/releases/tag/1.7.4

Maintenance activities update
------------------------------------------

Alessandro

* gdal_contour bug fixing https://github.com/OSGeo/gdal/issues/11564 to correct how levels and ranges were set by users or interpreted from the incoming data
* Implemented synchronization of OGR layer definition with savepoint mechanisms in GeoPackage and SQLite drivers (started as a QGIS bug but was decided it was best fixed in GDAL https://github.com/qgis/QGIS/pull/59797#issuecomment-2544133498)

Dan

* 'gdal raster calc', which is a no-python implementation that depends on the recently added GDAL VRT expression capabilities to lazily compute raster operations https://github.com/OSGeo/gdal/pull/11850
* 20+ PRs
* Accumulated stats and potential usage information from website format-specific driver pages to gage 

Even did not attend but provided the following text updates:

* RFC 106: Metadata items to reflect driver update capabilities https://gdal--11862.org.readthedocs.build/en/11862/development/rfc/rfc106_update_metadata.html
* RFC 107: IGetExtent / ISetSpatialFilter https://gdal--11862.org.readthedocs.build/en/11862/development/rfc/rfc107_igetextent_isetspatialfilter.html
* RFC 108: Driver removal for GDAL 3.11 https://gdal--11862.org.readthedocs.build/en/11862/development/rfc/rfc108_driver_removal_3_11.html
* Related to RFC 108, dropping as a maintainer of libogdi (this library probably no longer makes sense for anyone, the to-be-dropped OGR OGDI driver being likely its only user)
* Implementation of "gdal vector select" and "gdal vector sql"
* Implementation of "gdal raster mosaic" and "gdal raster stack"
* Brainstorming about a "gdal vector geom_op": https://github.com/OSGeo/gdal/issues/11826
* Usual mix of random fixes and pull request reviews


The next GDAL Maintainers Meeting is 03/27/2024 at 13:00 UTC. GDAL PSC members and PR contributors are welcome to join by reaching out to me for an invite.
