How to Create an InfoSWMM model from CSV Files, Alternate Method

How to Create an InfoSWMM model from CSV FilesAlternate Method

An InfoSWMM model can be newly created from a CSV file but it helps to have an idea of the maximum extents before you initialize the Arc Map project.  Use the ArcGIS default and Edit the extents of your future imported network (Figure 1).  Import the CSV files (Figure 2) and define the imported variables (Figure 3) followed by an Update Map from DB (Figure 4) which will draw your imported nodes and links on the Arc Map screen.  The updated Map should be within the extents of your defined spatial reference (Figure 5).  It is important to have the proper spatial reference for your imported data in Arc Map.  If you do not have the proper extents then when you update the Map from DB you will have a warning message "The coordinates or measures are out of bounds". 

Figure 1.  Import a background shape file and initialize your InfoSWMM map to the coordinates of the shapefile.

Figure 2.  Import a CSV file for both pipes and nodes using the Import Manager of InfoSWMM

Figure 3.  Set up the Field Mapping between the CSV parameters and the Node and Link Parameters of InfosWMM.

Figure 4.  Update the Map from the DB tables you just imported using the command Force All Network.
Figure 5.  The imported model has the same coordinates as the original imported shapefile.
