Hi I am trying to read this file, in theory based in ITRF https://webapp.csrs-scrs.nrcan-rncan.gc.ca/geod/process/download-helper.php?file_id=GSD95 (there is another one based in NAD83xxx)
However in with gdalinfo I see this: "Warning 1: CRS EPSG:4140 is deprecated. Its non-deprecated replacement EPSG:4617 will be used instead. To use the original CRS, set the OSR_USE_NON_DEPRECATED configuration option to NO." EPSG:4140 https://spatialreference.org/ref/epsg/4140/ is NAD83(CSRS98), that is not ITRF, as far as I know. However in byndataset.h there is this line: constexpr int BYN_DATUM_0 = 4140; /* ITRF2008 (GRS80 based WGS84) */ https://github.com/OSGeo/gdal/blob/master/frmts/raw/byndataset.h#L168 Are we parsing the header wrongly? There is some documentation in https://webapp.csrs-scrs.nrcan-rncan.gc.ca/geod/tools-outils/sample_doc_files/NRCan_Geoid_GridFormat_EN_2023.pdf I think what I say above applies to the field 16, Datum. Thanks Javier
