Beth and Becky's Geoeverything Presentation

1. Introduction to GeoEverything
by
Beth Leeder and Rebecca
Oliver

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

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. 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. Geotagging (Geocoding) Defined

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

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

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

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.

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
