Check the other examples in the folder to see how it is possible to obtain other fixed positions, and to create images that size dynamically with screen size.

Note that xunits and yunits can also be specified as "pixels" for precision control. For further detail, see the KML 2. The specified file can be either a local file or a file on a remote server. In their simplest form, network links are a useful way to split one large KML file into smaller, more manageable files on the same computer.

So far, all of our examples have required that the KML code be delivered to Google Earth from the local machine. Network links give you the power to serve content from a remote location and are commonly used to distribute data to large numbers of users.

In this way, if the data needs to be amended, it has to be changed only at the source location, and all users receive the updated data automatically. With some knowledge of a scripting language such as PHP, Python, or Perl, you can create a script that delivers a stream or file of KML data to each network link. The response must be valid KML. For complex applications, proper error handling is very important. Tip: A simple way to handle errors is to parse the server's error as the text for a folder name.

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.
