17. Google Earth?
• Google Earth is a computer program that renders a
3D representation of Earth based primarily on
satellite imagery.
• Free available for both Desktops and Smartphones
• Available as a Desktop application.
• Develop by Brian McClendon on 2007
• Imagery is updated every couple of years

18. How is the imagery collected?
Satellites
Satellites give us global views and that is all 2D imagery.
Google Planes
When we are closed to the ground, we need 3D data, that’s collected by
planes.
And constructing a 3D model.
Using computer vision to remove overlapping in the pictures.
If one computer process googles earth’s images they will take 60 years.

19. Version of the google earth
1. Google Earth pro
Google Earth Pro - This current desktop version, now free to use, has
many features, including displaying satellite and aerial imagery, a
growing set of layers of mappable data, the ability to display third-party
data, tools for creating new data, and the ability to import GPS data.
Can print and save high-resolution images.
Google has created a Google Earth Education site to provide helpful
information on using Google Earth with students.

20. Continue…
2. Google Earth for Web
Available for Chrome, Firefox, Edge, and Opera)- An easy-to-use,
browser-based version that provides ease of accessibility but is limited
in terms of functionality. This version can load kml or kmz files, can be
used to search for places, and can be used to follow a story from a
collection contributed by various individuals and institutions.
3. Earth Engine
Combines satellite imagery and geospatial data with many analysis tools
including the ability of the user to add their own algorithms for real-
world applications.

21. Each of these versions of Google Earth can be used to read and create
data in KML (Keyhole Markup Language) format, which enables
educators, students, and other users to share data.

22. CONCLUSION
People nowadays are fami liar with technology. With the development of
smart phones, Google Maps, which is an essential and portable tool on
directing,is getting more important and commonly-used.
It is also embedded in many websites and applications that people are able
to use it for different purposes,e.g.finding restaurants nearby and making
tax i calls.
It is likely that Google Maps will have a larger coverage of users in the near
future as mapping technology is getting accessible to everyone with the aid
of Internet.
Google Maps is one of the innovations in the decade that brings great
improvements to our lives.
