From the developer:
Wouldn’t it be nice to link them up and watch your little plane zooming across the Google Sphere (as it might soon be called) as you take the controls in X-Plane? Well you can. XPlane Centre is a simple app that connects to X-Plane and receives positional information (latitude/longitude etc.). It then centres a Google Map view on your current location, tracking you as you fly around in X-Plane.
You may want to check out more software for Mac, such as Build-a-lot 3, TravelRecorder or Travel Guide, which might be similar to XPlaneCentre.
