Google Earth is a virtual globe program that was originally created by Keyhole Inc. in 2001 and was later acquired by Google in 2004. It allows users to view satellite imagery and terrain of locations around the world. Google Earth has various features that let users explore Earth, the sky, oceans, and other planets. It has wide geographic coverage of countries and continents. Recent updates by Google Earth have provided street view imagery of new areas like Antarctica, Ireland, and Brazil to better showcase locations. Google Earth has business and research uses like location analysis and is also used in fields like real estate, defense, environmental research, and homeland security. However, some countries have banned it due to national security or privacy concerns.
