TerminologyTerminology
Geolocation:
• Identification of the real-world geographic location
of an Internet-connected computer, mobile device,
website visitor or other.
• Can include information such as country, region, city,
postal/zip code, latitude, longitude, altitude and
timezone.
• May refer to the practice of assessing the location, or
to the actual assessed location, or to locational data.

GPS:
• The Global Positioning System (GPS) - space-based
global navigation satellite system.
~Provides reliable* positioning, navigation, and
timing services
~All weather, day and night, anywhere on or near
the Earth
• Made up of three parts:
~Satellites orbiting the Earth
~Control and monitoring stations on Earth
~GPS receivers owned by users

Satellite:
• An object which has been placed into orbit by human
endeavor
• Sometimes called artificial satellites to distinguish
them from natural satellites such as the Moon
An animation depicting the orbit of GPS satellites

Geocaching:
• An outdoor activity in which the participants use a
GPS receiver to hide and seek containers (called
"caches") anywhere in the world
• Most often described as a "game of high-tech hide
and seek", sharing many aspects with orienteering,
treasure-hunting, and waymarking
• Quickly becoming a very popular hobby, as
evidenced by the new movie “Splinterheads”

Waypoint:
• a reference point in physical space used for purposes
of navigation
Waymarking:
• an activity in which people can locate and log unique and
interesting (and some mundane) locations around the
world, usually with a GPS receiver and a digital camera

• Where did your high-tech treasure hunt take
you?
• What difficulties did you encounter?
• What did you enjoy?
• How could such an activity be useful in a
classroom setting?

•Data Mashups

Your Assignment:Your Assignment:
• Choose a location to add to our VT graduate
student campus tour.
• Using your GPS, mark the waypoint and make
note of the latitudinal and longitudinal
coordinates.
• Take a photo of the location! Bring an
electronic copy of the photo to class, and
email a copy of the photo to me by Monday.
• Have fun!

“ The array of emerging web applications that combine
topographical data with geotagged media and
information are at the heart of geolocation’s
importance to educational practice. Many such
applications require no programming skills and can
be used by students to produce custom visualizations
layered over detailed maps or 3-D landscapes using
real-world data.”

Sharing Your FindingsSharing Your Findings
• Identify at least two things you learned about
GPS and geolocation technology from your
research
• Describe how GPS and geolocation technology
are being applied
• Identify the educational and/or research
significance for this application

Seven Things You Should Know…Seven Things You Should Know…
1. What is Geolocation?
• Associating a digital resource with a
physical location in terms of latitude and
longitude coordinates.
2. Who is doing it?
• Wikipedia
• Google Maps
• Google Earth
• Photo- and video-sharing web sites

Seven Things…Seven Things…
3. How does it work?
• JPEG image format
• includes placeholder for location data
• applications then relate that photo/video with
other place-based services, such as real estate
info or bus schedules

Seven Things…
4. Why is it significant?
• The extra layer of data can make the
resource more valuable to a broader
audience.
• Deeper understanding of the geographical
context as well as environmental, social, or
political factors.

5. What are the downsides?
•Data Overload
•Privacy Invasion
6. Where is it going?
•New tools for searching and organizing
information will develop
•Potential dovetail with emergent
cyberinfrastructure projects

7. What are the implications for teaching and learning?
Research implications:
•Sociologist studying dispersion of domestic
violence by neighborhood
•Epidemiologist tracking outbreaks of illness
•MBA student looking into regional purchasing
trends
**location data provides all of these scenarios opportunities to
see obscure patterns and gain a deeper insight into the topic
of study

7. What are the implications for teaching and learning?
Learning Implications:
•Activities that require taking a field trip
might be accomplished through
technologies that use location data to
coordinate information and resources
•Geolocation provides students the
opportunity to contribute to the body of
knowledge used by professionals in their
discipline
