Migrace dat Arc Hydro do Stormwater Utilities Network

Question

Účastnil jsem se schůzky Utility Network Workgroup 4. září a těším se na tu 9. října. V současné době máme naše Stormwater data v Arc Hydro. Těším se na migraci do řešení Stormwater Utility Network Foundation (bez přizpůsobení). Vytvořili jsme GDB v UN, ale máme určité obavy ohledně migrace dat. Arc Hydro uchovává nadmořské výšky u bodových prvků, zatímco v Utility Network jsou nadmořské výšky u liniových prvků. Migrujeme z verze ArcMap Geometric network Arc Hydro, nebo nejprve upgradujeme na Trace Network a pak migrujeme?

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.
