Hello Geodesists,

I am receiving data from custom 3D cartesian coordinate system I would like to define in ArcGIS Pro.

I computed the seven parameters to a 3D national system and there are equations to go from 3D cartesian to geographic that I believe ArcGIS Pro knows ?

It seems like I can define seven parameters method tranformation in ArcMap:

Equation-based methods—ArcMap | Documentation 

But I can't find a way to define a coordinate system as 3D cartesian.

Did I miss anything ?

Thanks

Haven't tried it yet but

Specify a coordinate system—ArcGIS Pro | Documentation 

shows how to define your own horizonal and vertical coordinate systems... 


... sort of retired...

Thanks for your reply.

That is not exactly what I am looking for. I am looking for X, Y, Z 3D coordinate (without ellipsoid definition).

Then you can directly compute lat, lon, and H when an ellipsoid is defined and easily work with well-known geodesic datum.

Maybe Melita Kennedy‌ will have an idea ?

We don't support 3D Cartesian in ArcGIS yet. It is in the Esri projection engine, but not exposed in the software using the library. I'm sorry!

Thanks for your reply.

I am not sure to understand: can it be somehow extended using Esri projection engine ?

Thanks !
