Multipoint feature class in Topology

[vijaybadugu]

When i try to add feature class to participate in topology. I was getting an error "The geometry type (MultiPoint) of the feature class is invalid for participation in a topology". is there a way to support or work around for this?

Direct Answer

Yes, ArcGIS Pro geodatabase topology does NOT support multipoint feature classes. When you try to add a multipoint feature class to a topology, you will get an error:

“The geometry type (MultiPoint) of the feature class is invalid for participation in a topology.”

Why is this the case?

Geodatabase topology in ArcGIS Pro is designed to enforce spatial integrity rules among point, line, and polygon feature classes.
Multipoint geometry is treated differently because topology rules rely on relationships like shared edges or coincident points, which do not apply well to multipoint collections.

Supported Geometry Types

Point
Polyline
Polygon
These can participate in topology and have associated rules (e.g., Must Not Overlap, Must Not Have Gaps, Must Be Covered By).

Workarounds

If you need topology-like validation for multipoint data:

Convert multipoint to single-point features using tools like Multipart To Singlepart or Feature To Point before adding them to a topology. 

Alternatively, use attribute rules or custom scripts for integrity checks on multipoint datasets.
