the latest version of GoogleEarth now has an applescript interface. so it’s possible to control the camera from outside. with apple’s cocoa libs it is even possible to call the applescript from within Processing.

Code:

import com.apple.cocoa.foundation.*;

float latitude = 48.169729;
float longitude = 11.553175;
float distance = 150;
float tilt = 0;
float azimuth = 0;
  
void setup()
{
  size(360, 90);

}

void draw()
{
  setViewInfo(latitude, longitude, distance, mouseY, mouseX);
}

void setViewInfo(float latitude, float longitude, float distance, float tilt, float azimuth)
{
  String script = "tell application \"Google Earth\"\n"

	    + "SetViewInfo { latitude:"+latitude+", longitude:+"+longitude+", distance:+"+distance+", tilt:"+tilt+", azimuth:"+azimuth+" } \n"
			+ "end tell\n";
  
  executeScript(script);
}

void executeScript(String script)
{
  NSAppleScript myScript = new NSAppleScript(script);
  NSMutableDictionary errors = new NSMutableDictionary();
  myScript.execute(errors); 
}
 

Do you know if there is any way to animate transitions between long/lat locations?  I'm working on a project that projects webcams on a vertical wall, and google earth on the floor.  I want them to be synced, so that when the webcam switches from Time Square New York to Prague, Czech Republic (for example), the projection of Google earth smoothly transitions to the new location.  It would behave like the Google Earth sightseeing play tour feature.
