TRANSCRIPT

  • Google earth:Anja MikicNovember 12, 2009

  • 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 geographicmaps, 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 Earths 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 youve 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

  • ucla (4000 FT)

  • crater on mars

  • underwater view

  • google sky

  • 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 KFCs Colonel face
