Mirror worlds are informationally-enhanced virtual models or “reflections” of the physical world.

- Constructions

  1. Sophisticated virtual mapping
  2. Modeling
  3. Annotation tools
  4. Geospatial and other sensors
  5. Location-aware and other lifelogging (history recording) technologies

Unlike virtual world, which can be wildly different from the Earth, Mirror World model the world around us.


- The Canadian Graphic Information System (GIS) was one of the first digital mirror worlds. Like all of the first digital mirror worlds, the Canadian GIS was a government-built public resource. Essentially, its main purpose was to stitch together digital maps to create larger areas of mapped land. The CGIS was also an essential stepping stone to the creation of

- Following the government-built digital mirror worlds, came proprietary pre-Internet systems like the Environment Rating Scales Institute's ArcGIS program. These digital mirror worlds were funded by businesses and institutional customers. ArcGIS focesed on working on, organizing, and analyzing geographical information for land-use planning. In 1973 they ERSI created the first commercially developed state wide graphic information system for Maryland.

- In 2005 came Google Earth and the emergence of digital information systems for military use. These digital mirror worlds were created with a typical cartographic surveys and additional enhancements of satellite and aircraft images. Some programs, like Google Earth, also used ground based imagery by mounting cameras on cars.

- In 2004 through 2006, Amazon developed BlockView, which was a failed effort to supplement online yellow pages with real world view of businesses and residencies accompanied by their surroundings. Though this attempt was unsuccessful, it did show how mirror worlds were becoming a more popular tool with services that the general population could access and utilize in day-to-day life.


- Mirror worlds have many main strengths

  1. Mirror worlds are practical. They are a reflection of the world at large and have many uses.
  2. Prevalent in everyday life - Whether viewing for business or pleasure.
  3. Used in real world applications including topographical and geographical work.
  4. Integrated in many applications. From Google Earth and Microsoft Virtual Earth to GPS and navigation systems.
  5. Becoming more and more popular for different industries (Ex. Yellow Pages).
  6. Has much more growing to do, its only forms are very basic.
  7. Easy access. Mirror world applications do not require much to run and are easy to find and download online, unlike other programs.
  8. Mirror world technologies are used in many other types of internet tools, primarily for its 3D visual mapping.

- Mirror worlds also have some weaknesses

  1. They require immense amount of work and research to develop. (sophisticated virtual mapping, location-aware technologies, and geospatial and other sensors).
  2. To keep maps up to date and standard, constant maintenance is required.

- The advancement of Mirror Worlds largely increases public transparency. This is hard to classify as a strength or weakness.
- Although Mirror worlds may not be flashy as lifelogging, virtual worlds, and augmented reality, they are more practical and have a stronger prospective future.


- There is a large future for the usage of Mirror worlds. Mirror Worlds are constantly improving in quality to be smarter and more accurate due to location and context-aware sensors.

- The development of "local positioning systems" will enable us to track and locate things we care about like tools, children, friends, wallets, and car keys.

- Mirror worlds are also becoming more useful tools for homes in regards to security, property insurance, moving and storage, rentals, interior decorating, and construction. In this aspect, Mirror Worlds can be used to increase crime prevention and privacy protection at significant amounts.

- GPS on our phones will be enhanced and more helpful when locating restaurants or gas and eventually people.


Google Earth

  • How does it work? - Every time the program is opened, it connects to the Google’s server, allowing the user to access terabytes of geological, political and social datas in 3D map.
  • How is it used? - Users can access the Google’s map database and perform: Mapping and directions, Local Search, Sightseeing

Bing Maps Platform (Previously, Microsoft Virtual Earth)

  • How does it work? - It connects to the ArcGIS server database to create 3D map. This server and Map is built in some of the electronic products in order to access the map.
  • How is it used? - It is used for the users to easily create map datas. Also, It allows the users to create map informations for different applications.

GW Virtual Tour

  • How does it work? - When people go to http://virtualtour.gwu.edu/ they connect to GW’s server and are given access to 360 degree views of hot spots on GW’s campus.
  • How is it used? - It is used mostly by prospective students who want a more interactive and complete view of the campus instead of just a picture.


  • How does it work? - GPS device connects to the satellites to locate the current location and destinations. The map itself is downloaded in the Device itself and can be accessed by the users when needed. Some supports the 3D versions of the map.
  • How is it used? - Users will be able to search and locate their destinations, and the device would guide the user to the destinations. User should frequently update

the GPS device to access the new locations.
