[kareemamir]

in one of the threads a user aksked about making movies from google earth. there was a reply saying another user, uses Snag It!, http://www.techsmith.com/snagit.asp. another thread there was user aksing if anyone would like to see any airports in 3d. he uses sketchup

the reason im saying all this, does any one know of any other tools that can enhance google earth?

thanks
