custom coordinate system SRID with PostGis

jherbst5

Hello all,

This is my first post here. I am just getting started with a PostgreSql/PostGis database in ArcGis Pro. I have successfully connected the database to ArcGis and I am able to move GIS data back and forth using various methods. However in the excavation where I work, we use a custom coordinate system and the GIS data from PostGis appears in Layer Properties>Source>Spatial Reference: Unknown Coordinate System. I have added our coordinate system to the spatial_ref_sys table in the database and its recognized by QGIS fine but not ArcGis.

I have searched around how to get ArcGis to recognize the SRID and found a couple of old posts from 2013 and 2018:

https://community.esri.com/t5/geodatabase-questions/accessing-a-postgis-table-with-a-custom-srid/td-p/782976

https://community.esri.com/t5/arcgis-enterprise-questions/add-data-query-with-custom-srid/td-p/442991

The posts mention a "back door" method of adding a custom system that ArcGis will recognize. Does anyone happen to know this method or any other way?

Thank you,

James
