Hello,
We want to help users with some custom coordinate systems to choose the right transformation to apply to their data.
We have a database of these CRS in a system similar to EPSG Geodetic Parameter Dataset. We create some "bound CRS" with a specific custom code and a specific authority to make a transformation preference.
We have already implemented these bound CRS as new CRS in proj to use them with some open source libraries (proj, part of gdal/rasterio), software (QGIS), and databases (PostGIS) with the same base of proj for all these apps.
We are trying to find a way to do this in Esri and we found this: Installer des fichiers de système de coordonnées supplémentaires—ArcGIS Pro | Documentation. Unfortunately, there is no documentation.
We also tried to implement some prj files in the user folder but:
Do you have any solutions to propose to us to improve the management of CRS for our users?
Thanks for your help
Guillaume
