Currently, when the Align Parcels tool merges overlapping points as a result of an alignment it appears the tool preserves the point with the higher Object ID.
For our organization, we need the tool to preserve the lowest Object ID, since this has implications for our publication system. We currently produce a Change Vector spatial product that allows organizations that consume our parcel mapping data to keep their data in alignment with our parcels. This change vector spatial product tracks how existing points in the parcel fabric move. So, as much as possible, we try not to overwrite existing fabric points.
Currently, our organization is working on ArcGIS Pro 3.2, and we are running into BUG-000162466: Align Parcels does not merge coincident points if you are projecting on the fly. So, for us, the Align Parcels tool does not currently merge points anyway. We run the Delete Identical tool based on shape afterwards – and the Delete Identical tool does preserve the lower ObjectID. So far as we know, this bug has been fixed at version 3.3, so we would like also for the Align Parcels tool to be enhanced to preserve the lower ObjectID when merging points (or at least provide the user an option – preserve new or preserve old – keep in mind this has nothing to do with the spatial location of the point, this is just about what object ID is preserved).
