Migration von Arc Hydro-Daten zum Stormwater Utilities Network

Question

Ich habe am Utility Network Workgroup-Treffen am 4. September teilgenommen und freue mich auf das Treffen am 9. Oktober. Derzeit haben wir unsere Stormwater-Daten in Arc Hydro. Ich freue mich darauf, zur Stormwater Utility Network Foundation-Lösung zu migrieren (ohne Anpassungen). Wir haben eine GDB in UN erstellt, haben aber einige Bedenken bezüglich der Datenmigration. Arc Hydro speichert Höhenangaben bei den Punkt-Features, während im Utility Network die Höhenangaben bei den Linien-Features liegen. Migrieren wir von der ArcMap Geometric network-Version von Arc Hydro oder aktualisieren wir zuerst auf Trace Network und migrieren dann?

If you use the simple data mapping/create migration workspace process to get started, it will create the initial mappings, data model, and migration for you (including adding and mapping any fields from your Arc Hydro model). This would do most of the work for you, but you will still need to transpose the elevation values using the method you feel most comfortable with.

Our path forward then will be to create, within ArcHydro, custom fields populated with values that match the schema of the Stormwater Utility Network. Then we would append the modified ArcHydro data and Append to the appropriate Feature Class in UN. Then, either we build a Python custom tool or manually transpose elevation values within UN.

I'm not aware of any custom tools built to do this, but it could be done with some Python. You would populate the upstream elevation of a pipe with the elevation of the point feature at the first/from vertex of the line, and the downstream elevation of a pipe with the elevation of the point feature at the last/to vertex of the line.
