Exporting a HEC‑HMS Model to Google Earth

It is quite easy to export a HEC-HMS model to Google Earth, allowing the HEC‑HMS model data to be viewed in Google Earth.

Follow these steps to display the Export HEC‑HMS to Google Earth command:

1. From the Input ribbon menu, select Export Data menu item and then Export HEC‑HMS to Google Earth command.
   
2. The Export HEC‑HMS to Google Earth dialog box will be displayed.
   

The following sections describe the Export HEC‑HMS to Google Earth command and how to interact with the above dialog box.

Google Earth File

This section is used to define where the exported results are to be saved.

Click the […] button at the File name entry to specify the directory location and Google Earth file name to save the exported results.

HEC‑HMS Input Data

This section allows the user to select what HEC‑HMS element data should be exported. Each HEC‑HMS element type is placed in its own layer. For example, subbasins are placed in the subbasin layer, whereas storage areas are placed in the storage area layer.

Other Options

The Overwrite existing Google Earth file checkbox option allows the software to overwrite an existing Google Earth file with the same file name.

The View in Google Earth checkbox option causes the software to launch Google Earth from the user’s computer, load the exported Google Earth file, and then zoom into the project area in Google Earth. The Google Earth application must already be installed on the computer for this functionality to work seamlessly.

Exporting the HEC‑HMS Model

After the options have been defined, click the [Export] button and the software will export the HEC‑HMS model to Google Earth.

Only the current scenario (or plan) will be written out to a Google Earth file. Separate Google Earth files will need to be created if multiple scenarios are to be viewed in Google Earth.
