This is more informative and more user-friendly than letting the connection drop. Whenever the network link is refreshed, the Python script runs again and generates KML with new latitude and longitude values. A standard network link is a uni-directional link: data flows only from the server to Google Earth. The view-based refresh enables bi-directional communication.

When the view-based refresh is active, Google Earth returns the view coordinates to the server at a specified time. This may be every n seconds, minutes, or hours, or once a certain amount of time has elapsed since the view stopped moving. The coordinates are returned to the server by means of an HTTP GET that appends the coordinates as follows this is the default bounding box information :.

If the request were made while the user was looking down on San Francisco, the coordinates might look as follows:. This feature can be used for some very creative applications, but to get you started, a simple example is presented below. The following server-side Python script parses the return message sent by Google Earth and responds with a Placemark at the center of the screen. Each time the Network Link is refreshed, a new Placemark is generated.

The principle illustrated in this example can be used for some very complex applications. For example, if you have a database of geographic information, you can extract the coordinates of the viewer, make a call to the database for the data specific to the view, and return it to Google Earth as KML. When responding to a request from Google Earth or any Earth browser , a KML server must follow a certain set of rules so that Google Earth can correctly interpret its responses.

If the server returns invalid KML, the Network Link will stop, deactivate, and output an error message. Ready for more?
