A 3D mapping program from Google that covers the entire globe from satellite images.
- How does Google Earth work?: It maps the Earth by superimposition of images obtained from satellite imagery, aerial photography, and GIS 3D globe.
- GIS 3D globe:(geographic information system)a world mapping software with GPS tracking, which utilizes custom national geographic maps, topographic maps, aerial photos and more.
GPS: global positioning system
- a U.S. owned utility that provides users with positioning, navigation, and timing services
- GPS was developed by the US Department of Defense for use by the United States Air Force and Navy
- it consists of 24 operating satellites that orbit the Earth
- GPS is made up of 3 parts: 1)satellites orbiting the Earth; 2) control and monitoring stations on Earth; and 3) the GPS receivers owned by users.
history of google earth:
- created by KeyHole Inc., and originally called Earthviewer 3D
- Earthviewer 3D was released in 2001 and in 2004 Google acquired the company and relaunched and renamed it Google Earth one year later in 2005
- as of now, the most recent version is Google Earth 5.0
Features & accuracy-Most land areas are covered in satellite imagery with a resolution of about 15 m per pixel.
- “Google Earth acquires the best imagery available, most of which is approximately one to three years old.”
- However, Google Earth’s maps are being updated every 5 minutes
- available in 37 languages- flight stimulator- google sky- street view- oceans- Mars- Moon
New features in google earth 5
- historical imagery: if you’ve ever wondered how your neighborhood or city has changed over time, google earth 5 lets you go back decades, giving you access to the past
- ocean floor: you can see beneath the surface of the ocean and explore 3D shipwrecks like the Titanic
- touring: decide where you want to go and take a tour through google earth, and even add music or narration
the future
"Google's mission statement is to make all the world's information universally available and useful”
- virtual worlds: incorporate the images into video & computer games
privacy- U.S. laws do not prohibit Google from taking photographs in public places
- because of the potential of terrorists to use Street View/ Google Maps, Google blurs some areas for security reasons such as the White House and the U.S. Naval Observatory
- for Street View, Google has an algorithm that automatically blurs the faces of people on the streets, billboards, even KFC’s Colonel face
