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.

TerminologyTerminologyGPS:• 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

TerminologyTerminology

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

TerminologyTerminology

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”

TerminologyTerminology

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?Think About:Information Age vs. Interaction Age

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.

Seven Things…Seven Things…

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

Seven Things…Seven Things…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

Seven Things…Seven Things…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
