Extracting elevation

Step-by-step Guide

When you import a model and make manual fixes and adjustments, junctions may not have elevation data. The InfoWater Pro Elevation Extractor can be used to populate junction elevations using the raster elevation dataset.

1. Open the appropriate .aprx file in ArcGIS Pro.
2. From the ribbon, InfoWater Pro tab, click Initialize.
3. From the ArcGIS Pro toolbar, Map tab, Layer panel, click Add Data.
   
4. In the Add Data dialog box, browse to and double-click the desired .gdb file to expand it, such as CityData.gdb for this exercise.
5. Select the raster data set you need, in this case, elevation.
   
6. Click OK.
7. On the InfoWater Pro ribbon, in the Edit panel, click DB Editor.
   
8. In the Open Table – Junction Information dialog box, Data Table tab, expand the Element Information Data folder.
9. Double-click Junction Information.
   

The Junction Information table populates the DB Editor. Notice that the Elevation column is empty.

10. Click Exit to close the DB Editor.
    

You can use the Elevation Extractor to populate the elevation information, but be aware that this tool only accepts raster files.

11. From the Command Center tab in the Model Explorer, expand the Tools folder.
12. Double-click Elevation Extractor.
    
13. In the Elevation Extractor dialog box, set the Source Layer to elevation. (If you do not see “elevation” listed here as a layer, then the elevation data is likely in another file type.)
    
14. Click Extract.

The Elevation Extractor takes the value of the pixel corresponding to each junction and assigns it in the Elevation field of the InfoWater Pro Information Database Table.

15. When you see a confirmation in the Message Board that the elevation data extraction is finished, close the extractor.
    
16. Re-open the database editor by selecting DB Editor > Element Information Data > Junction Information.

You can see that elevation data is now contained in the database table:
