Informations supplémentaires

The behavior is expected. As it is possible that gtdefalts.json file is used to get the default transformation. If the transformation 108190 is used then 1 meter offset is expected. The transformation that should be used is NAD_1983_To_HARN_MD_DE, 1485, which has a smaller offset between NAD83 and HARN (cm-level) - user needs to specify it. The service is using gtdefaults.json file, and in this case, it's the wrong answer.
