When you use the GIS Gateway to create new features or update changes to existing features, you can compare and identify what model elements will be added or modified when the GIS exchanges are completed.
To help see the differences more clearly in the comparison, hide the Junctions layer and temporarily un-map the PIPEHYD->LENGTH field:
Note: You are temporarily un-mapping this field for the sake of comparison; otherwise, all the pipes in the model will show as having a different length.
This comparison table identifies field changes that this exchange cluster will make. The fields highlighted in red represent those that are different between the two sources. For example, you can see that several pipes have been upsized to 12 inches.
Use the table to identify differences between the GIS and model to determine which elements and fields will be updated when the exchange is run.
To re-map the pipe length field:
