Google Earth

Definition

Google Earth is a virtual globe, map, and geographic information program first released by Keyhole, Inc., acquired by Google in 2004. The application displays satellite imagery, aerial photography, and various forms of public data over a 3D globe, enabling users to see cities, landscapes, and other geospatial data from multiple perspectives.

Examples

Exploring Famous Landmarks: Users can zoom in on landmarks like the Eiffel Tower in Paris, the Statue of Liberty in New York City, or the Great Wall of China via satellite imagery.
Geographical Analysis: Scientists and researchers utilize Google Earth to study geographical phenomena and changes, such as deforestation in the Amazon rainforest or the effects of natural disasters.
Virtual Tourism: Individuals and educators conduct virtual tours of historical sites or natural wonders for educational or recreational purposes.
Urban Planning: Urban planners and developers use it to visualize existing land use and plan new developments or infrastructure projects.
Real Estate: Real estate professionals can assess property locations, neighborhood characteristics, and geographic context for potential buyers or investors.

Frequently Asked Questions

What are the main features of Google Earth?

Google Earth offers various features, including 3D views, Street View, historical imagery, annotations, and the ability to import GIS data. It also integrates with other Google services like Google Maps.

Can I use Google Earth for free?

Yes, the base version of Google Earth is free to use. However, there are additional professional versions, like Google Earth Pro, which offer more advanced features and data sets.
