Through a simple PHP script, the Google Earth interface can report the following information about the viewer's location 1) The lat/long of the vertices that make up the minimum bounding rectangle of the view. 2) The viewer's tilt 3) The viewer's heading 4) The viewer's range 5) Horizontal Field of View 6) Vertical Field of View What I am looking for is a PHP script that calculates the exact coordinates of the viewbox--not the minimum bounding rectangle (The MBR equals the viewbox when the heading is 0,90,180, or 270 degrees). Basically you have to use trigonometry to take into account the tilt and heading. I will provide the scripts so you can view these variables changing as you move around in the Google Earth interface.
## Deliverables
1)A functioning PHP script that who's accuracy I will verify on a 3rd party web server based on parameters passed to it via the Google Earth interface. Upon verification, the source code of the script will be delivered.
2) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased.
