Import Index Points

Index points are only required when imported water surface elevations in hydraulics will be used to retrieve graphical stage-frequency functions. In other words, index points are not explicitly used for anything else within HEC-FDA, but remain an important concept. Import index points in the form of a point shapefile (only one index points dataset can be imported into a study).

If desired, create index points for the study. Index points should be created when retrieving graphical stage-frequency from water surface elevations in hydraulics. From the Study Tree, right-click on Index Points and select the create new command.
From the Create New Index Points dialog, enter the name and description for the data. Click the browser ellipse button to navigate to the appropriate file and click Open to set the shapefile path. Then select the unique name (a field of the attribute table). Click OK to import the dataset.
