Understanding GIS Exchange Clusters
Describe how GIS Gateway clusters can be used to update model elements.
Step-by-step:
In InfoWater Pro, the GIS Gateway provides data-exchange management that allows you to quickly load and save data between InfoWater Pro and GIS data sources.
- From the ribbon, InfoWater Pro tab, Exchange panel, locate GIS Gateway.
GIS Exchange Clusters define a set of data-exchange parameters. These parameters control how the data is loaded from GIS sources into InfoWater Pro, and vice-versa, if needed.
Model creation and maintenance are simplified by saving exchange clusters that can be used repeatedly, increasing the sustainability of model updates. It also makes it easier to maintain a one-to-one, model-to-GIS relationship.
Once a new GIS Exchange Cluster is added into the GIS Gateway, records can be created, updated, or deleted.
Modifications to the Domain or Active Network can be limited for all these exchange operations. This can be especially useful to limit the scope when deleting non-matching records, so as not to delete elements outside of the domain or active network that you want to keep.
Other options that help define the clusters include:
- Relate Type: Select whether to use Tabular Join, based on a common ID, or Spatial Join, based on geographic location.
- Where Clause: Create an SQL script to limit the query to specific items. For example, WHERE Install Year > 2023.
- Update Geometry Data: When this box is checked, the physical geometry of the data file being exchanged will be updated to reflect recent changes.
All GIS Exchange Clusters are saved for re-use, editing, or cloning.
Before loading a GIS Exchange Cluster to run, preview the changes using the Compare functionality. Depending on the exchange operation, the GIS Data Difference table displays information on elements to be added, updated, or removed. Attribute changes are highlighted in red. Update changes can be logged to a text file.
