Introduction to GeoEverything
Beth Leeder and Rebecca
The 2009 Horizon Report, “Geo-
Everything” will significantly impact teaching,
learning, research and creative expression
within the next two to three years.
Geotagging – What does it mean?
Location Aware Devices (LAD)
Implications for Higher Education
Content and Learners
Considerations for Implementation
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

New LAD automatically receive geolocative information.

Not a new technology, but increasing easier to use.

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
Global Positioning System (GPS)
Is a constellation of 27 (24
working/3 spare) earth orbiting
Each working satellite orbits
(circles) around the earth twice
At any given time, at least 4
satellites are “visible” in the
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

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
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

GeoEverything Uses for Higher
Mashups – "a web page or application
that combines data or functionality
from two or more external sources to
create a new service.”
Why Use Mashups for Higher
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.
Application in Higher Education
Research tool for science, medical, political, journalism
Science and Technology Curriculums - Tracking migration
patterns of animals, monitoring geological activity
Conducting Virtual Field Trips without leaving the classroom or
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
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
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
File size – larger files require more storage and take
longer to download
