I purchased FSDiscover from Flight 1 and now see a product called FS Earth (see below). I'm wondering are these add-ons compatible, can they work together or is there some overlap? Seems that FS Earth in conjunction with Google Earth brings a more vivid scenery that the stock views in FSX. "FS Earth for FSX Version 4 FS Earth for FSX version 4.0 is available. FS Earth acts as an interface between Flight Simulator and Google Earth, letting to follow a flight in real time, over the satellite images generated by Google Earth. Flights can be saved, and many options are available for fine tuning the performance, as well as the map's style (zoom, tilt, orientation). Works on a single computer running Flight Simulator and Google Earth all together, or, for best experience, can be used on two networked computers running respectively Flight Simulator (master) and Google Earth (slave). Supports flight plan, AI traffic and multiplayer aircraft display inside Google Earth, course prediction for own aircraft and AI traffic, and more. Version 4.0 adds spatial three-dimensional representation of aircrafts and paths, and other improvements."

I don't think FS Earth displays anything inside FS.FS Earth shows you the aircraft position superimposed on Google Earth imagery outside of FS.FSDiscover work inside FS. I don't think these overlap.
