Create UpDown Table
Description
Generates "UpDown" (connectivity) table that identifies upstream and downstream connected linear features (via HydroIDs) Output table name is fixed and is a concatenation of the input drainage line name and suffix "_UpDown". It is placed in the same geodatabase where the input sources reside. The output table has the following attributes:
- FeatureID – HydroID of the input line feature.
- ConnID – HydroID of the connected linear features (excluding the feature itself).
- UpDownType – "Down" indicates downstream feature and "Up" upstream feature.
- Flow split table is a required input for this function and must correspond to the input drainage line feature class (can be created using Find Next Downstream Line function).
