I'd like to see examples of behaviour before and after this change. I think the changes looks sound but a bit of help to grasp the consequences would be appreciated. |

Forgot to mention this adresses https://lists.osgeo.org/pipermail/proj/2024-September/011494.html Before: only NKG transformations: After, also include ITRF2020 <--> ETRFxxxx time dependent Helmert transformations: The NKG ones should are still taken in their area of use since they have a lower value for the accuracy field Example in Estonia: |

Thanks. It does indeed look sound! |

…target CRS that have the same originating authority Fixes https://lists.osgeo.org/pipermail/proj/2024-September/011531.html i.e. ``` projinfo -s EPSG:4269 -t EPSG:6318 --3d --spatial-test intersects ``` The fix consists in making sure that we recognize that the 3d-promoted object EPSG:4269 (NAD83(86)) is still linked to EPSG, and thus discard ESRI 3D objects in findsOpsInRegistryWithIntermediate() Fixes a "regression" of OSGeo#4244 (one could argue which of the results is the best, given that NAD83(86) as a 3D geographic CRS has no solid foundation)
