Hi, Please read the forwarded email below if you perform ETRS89-related coordinate transformations. To mitigate those issues, I've generated Docker images based on the GDAL v3.12.3 tag reverting to PROJ 9.7.1 (note the -r1 suffix): * ghcr.io/osgeo/gdal:alpine-small-3.12.3-r1 * ghcr.io/osgeo/gdal:alpine-normal-3.12.3-r1 * ghcr.io/osgeo/gdal:ubuntu-small-3.12.3-r1 * ghcr.io/osgeo/gdal:ubuntu-full-3.12.3-r1 Note that GDAL Docker -latest images use PROJ master (still affected by those 9.8.0 issues). I don't plan to change that, since it can be useful to test fixes as they land in PROJ master . GDAL 3.12.3 (and gdal-master) Conda builds are currently at 9.8.0. Track https://github.com/conda-forge/gdal-feedstock/issues/1191 for a potential revert to 9.7.1 Even -------- Message transféré -------- Sujet : [PROJ] ETRS89 issues with PROJ 9.8.0 Date : Sun, 5 Apr 2026 18:53:01 +0200 De : Even Rouault via PROJ <[email protected]> Répondre à : Even Rouault <[email protected]> Pour : proj <[email protected]> Hi, We're hearing alarm bells coming from various European users related to transformations between pre-ETRS89 national CRS an ETRS89-based CRS, caused by significant changes in that area that have been introduced in the EPSG dataset embedded in PROJ 9.8.0. Namely the creation of ETRS89-XXX datums where XXX is the ISO code of the country. https://github.com/OSGeo/PROJ/pull/4736 exposes a few of the issues met, and a partial workaround, but not covering all cases. Please also report issues you might hit in that area. We are working with EPSG to help fix the situation. For people mastering their supply chain, reverting back to 9.7.1 might be prudent.
