How can I get live data from Google Earth program?
Unfortunately, you can't get live data from Google Earth program. The application is using old pictures and some places are not updated for many years. If you have issues using the software, check the tutorials provided by the developer. Also, you can check Google Earth Help Center.
Not unless we have satellites constantly taking live footage of the world 24/7. Even if we did, it would be slow I would think. The satellites would have to relay the feed back to earth, and then we would have to serve it to millions of users.
