Export to KMZ file for Google Earth

Item Description
KMZ file name Specify a location and a filename for the export file (extension .KMZ), either directly or by using the Browse button Browse.
Projection Select the required coordinate system from the drop-down list.
Optional Server URL

This allows you to export the data as a collection of .KML and .PNG files to be served to Google Earth as required. This is recommended for large networks as performance is significantly improved if data is accessed by Google Earth via a server.

The URL entered here is the root of the URL of the server.

In addition to the .KMZ file, a .ZIP file of the same name is created. This will contain all the files that the server must be ready to serve to Google Earth when the .KMZ file is opened in Google Earth. The .ZIP file includes .KML files and .PNG files. The user must place the files manually onto the server. KML files are fetched with a /kml/ prefix and other files are fetched with a /gefiles/ prefix.

Note

If the Server URL is given as http://Myserver/, KML files will be fetched as http://Myserver/kml/filename.kml and .PNG files will be fetched as http://Myserver/gefiles/filename.png.
Options
Only visible layers If this option is checked, only the layers marked as visible on the GeoPlan window will be included in the export.
Only selected objects If this option is checked, only the objects selected on the GeoPlan will be included in the export.
Omit object names If this option is checked, node and link object names are not shown on the Google Earth overlay. If the names are being shown (Omit object names checkbox unticked), the associated scaling factor controls the font size of the name labels.
Omit object descriptions If this option is checked, the tables of object field values used to fill in the balloons are not included in the export.
Omit results If this option is checked, the Results Options controls are disabled and no simulation results are included in the export.
Tile Size

Max nodes per tile This option is enabled when the optional file server is in use and controls the size and number of tiles required to cover the network and provide the fully detailed view of the network when the user zooms in.

If the export network has more nodes than the max nodes per tile setting, the export will be subdivided into a rectangular grid of tiles so that no tile has more than the requested number of nodes. In such a case, the Google Earth user will see a reduced-detail overview, resolving into full-detail tiles as they zoom in.
Results Options

The options in this group are enabled if the Omit results checkbox is not ticked.

Group by timestep By default results for all the timesteps are grouped below each object in the Google Places pane, making it easier to hide specific objects. If this option is checked, timesteps appear above objects in this hierarchy, making it easier to hide specific data for specific timesteps.
Timestep multiplier Can be changed from the default value 1 to cause only results for every nth timestep to be included in the export.
