- 2. The 2009 Horizon Report, “Geo- Everything” will significantly impact teaching, learning, research and creative expression within the next two to three years. O

- 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.

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 out.com/ 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. 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: http://electronics.howstuffworks.com/gadgets/travel/gps4.htm
- 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 http://images.google.com/imgres? the phone is switched on. imgurl=http://www.websafecrackerz.com/images/furniture/3 g_us_phone_diagram.gif http://www.mobilelocators.com/how.php

- 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.” http://en.wikipedia.org/wiki/Mashup_( web_application_hybrid)
- 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. http://blog.blackboard.com/blackboard/2008/09/mashups-in-the.html
- 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. 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. 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
