Hi there, In our application, we integrate GDAL (3.8.4 with proj 9.4.0) in order to deals with geographic projections and data loading. To improve loading & processing time we use multithreading. Until now everything was right, but we start dealing with dataset expressed on EPSG:28992 (Amersfoort / RD New -- Netherlands - Holland - Dutch). Then our application starts to crash. After some investigations, it appears that PROJ is modifying the pipeline used to perform transformation. (Into pipeline, some pop operation)
We use OGRCoordinateTransformation into a wrapper, each Transformation object is unique throught the whole application (I.E. one object to convert EPSG:4326 to EPSG:28992). For now this implementation works wells (At least for UTM / Lambert / WorldMercator, maybe anothers) but for this particular one don't. Did we miss something ? Should we have a threadlocal based implementation on OGRCoordinateTransformation object ? Thanks ! C2 - Usage restreint
