  1. 1. Introduction to GeoEverything by Beth Leeder and Rebecca Oliver
  2. 2. The 2009 Horizon Report, “Geo- Everything” will significantly impact teaching, learning, research and creative expression within the next two to three years. O
  3. 3. Objectives  GeoEverything Defined  Geotagging – What does it mean?  Location Aware Devices (LAD)  Implications for Higher Education  Content and Learners  Other uses  Considerations for Implementation
  4. 4. What is GeoEverything?  An emerging technology – implication for education more evident in 2-3 years  Seeks to answer “What am I doing right now in relation to the world?”  Gives people, places and things (every physical object) a location via:  GPS assisted Location Aware Devices (LAD)  LAD automatically record geo-locative data onto a variety of captured media.  New LAD automatically receive geolocative information.  Transmitted data to a web server or web-based application  Not a new technology, but increasing easier to use.
  5. 5. Geotagging (Geocoding) Defined Ge otag g ing a dig ital photo or othe r ob je ct on a We b s ite or in a docume nt re fe rs to the attachme nt of g e og raphical ide ntification data. http:// ps .ab g od/ los s ary/g / e otag .htm g g By using a set of unique coordinates, expressed as longitude and latitude (and sometimes altitude) the location of object, place, or person on Earth can be detected by G P S receivers. Mobile phones, cameras, and other handheld are beginning to include features that make use of geolocative data. We will look at two different methods of receiving geolocative data: GPS and Mobile
  6. 6. Global Positioning System (GPS)  GPS:  Is a constellation of 27 (24 working/3 spare) earth orbiting satellites.  Each working satellite orbits (circles) around the earth twice a day.  At any given time, at least 4 satellites are “visible” in the sky.  To determine location, a GPS receiver locates 4 or more satellites, calculates distance to each, and uses information to deduce its own location, this process is called “Triliteration”  Newer cell phones contain a GPS receiver For more information about GPS go to:
  7. 7. Mobile Phone Tracking  Mobile Phone Tracking:  Mobile phone tracking technology works by measuring the distance the phone's signal has to travel to the nearest mobile masts based on time and signal strength.  A triangulation calculation is made and the position is plotted on a web map.  As it relies on a mobile's signal it can only locate a mobile if the phone is switched on. imgurl= g_us_phone_diagram.gif
  8. 8. Geotagging Examples  Ge otag g e d dig ital imag e s : include pre cis e latitude and long itude coordinate s , and pos s ib ly altitude along w ith othe r information. This pe rmits the imag e or othe r ob je ct to b e e as ily and pre cis e ly pos itione d on a map, putting the g e otag g e d imag e into conte xt, and making it more e as ily s e archab le .  W b s ite s , s uch as Goog le Earth, GEODE, and e Flickr allow s us e rs to upload g e otag g e d photos . http://g ps .ab od/ los s ary/ /g e otag .htm g g

  10. 10. GeoEverything Uses for Higher Education  Mashups – "a web page or application that combines data or functionality from two or more external sources to create a new service.”  web_application_hybrid)
  11. 11. Why Use Mashups for Higher Education  Current data, for example:  Election mashups show you the current status of an election as it happens.  Google Map mashups show you current events as they happen around the world  Interactive: Mashups immerse students in the educational experience.  For example Google Earth provides the ability to follow historical events and review more than 50 years of U.S. Geographical Survey data.  Engaging: Because they are always relevant and immersive, and because they bring students into the learning process, mashups have the potential to be highly engaging.  Implement mashups into your curriculum. For example, Social Science students access census related assignments through Google Maps. 
  12. 12. Application in Higher Education  Research tool for science, medical, political, journalism students. Examples:  Science and Technology Curriculums - Tracking migration patterns of animals, monitoring geological activity  Conducting Virtual Field Trips without leaving the classroom or residence  Simulated games using GPS guided handheld computers to investigate environmental accidents and events  Search maps for a multitude of media including sounds, images, videos to enhance the learning process
  13. 13. GeoEverything and the Adult Learner  Adds additional dimension to traditional learning  Allows the learner to visualize, experience, and become immersed in the learning material  Supports adult learning methodology  Makes learning relevant and meaningful  Supports a self directed learning approach  Support individual learning styles: Visual, Auditory, Kinesthetic, and Environmental  Allows for community based, authentic problem solving
  14. 14. GeoEverything Issues  Privacy – preventing inadvertent, deliberate, or malicious tracking of individuals  Intellectual Property Rights – who owns what?  Server storage – what will the impact of multiple files of the same images and data be on the server. Who cleans up the server and what criteria will be used for maintenance?  File size – larger files require more storage and take longer to download
