Elevation Extractor, as the name implies, extracts elevation for nodes from digital topographic maps such as the DEM. The elevation extractor interpolates ground surface elevations for the nodes in the distribution system from digital maps of various formats including vector data, raster data, and spot elevation data and other digital contour data formats compatible with ESRI ArcGIS.

To do elevation extraction, go to the Model Explorer, click the Command Center tab on the bottom, navigate to the Tools group, and click the Elevation Extractor.

Select the Source Data Format - This refers to the format of the digital topographic map (contour map) that contains elevation information of the distribution system. InfoWater accepts Raster Data Formats, Vector Data Formats, Spot Elevation Data Formats (i.e., Point Elevations).

Specify the source of the digital map, i.e., the Source Layer.  Note that, you must load the digital map to the InfoWater project as a layer before you run the elevation extractor. Use the Add Data button from the Map tab of ArcPro to select and add a layer containing elevation data. Please Note: The layer containing the elevation data and the current active project data layers must be on the same spatial reference for the elevation extraction to work properly. If they are not on the same spatial reference, either inaccurate elevations or no elevation will be extracted. 

Specify name of the data field of the Source Layer that contains the elevation information in the Elevation Source Field.

If required, check Recalculate Pipe Length Based on Elevation Data to calculate 3D pipe lengths using X, Y, and Z coordinates.  Check Skip Node Elevation Update to just calculate pipe lengths from 3D data without modifying elevations.

If you want the elevation extracted only for the data elements contained in a domain, check the Apply To Domain Only box.

Finally, You may click the Extract button to run the elevation extractor, or the Close button to close the window.
