3. Convergence A device that is made for one purpose but is developed to carry out other functions Can you think of an example ? Primary function phone calls but now include cameras, music players, surfing the internet, watching videos and GPS.

4. G lobal P ositioning S ystem Uses distance measurements from 3 satellites to work out the user position. Satellite- based navigatio n system 24 satellites GPS receiver compares time signal transmitted by satellite with time received

5. Uses of GPS Find your way to a specific location. Tell you the distance to a specific place. e.g. 2 miles to the Eiffel Tower Give you the location of something e.g. train station

6. GPS Receivers

7. Geocaching http://www.geocaching.com/videos/default.aspx Outdoor treasure hunting game Players locate hidden containers call geocaches using GPS enabled devices Share their experiences online

8. Metadata Information about the content of a digital item The information is embedded within the file E.g. an image taken on a digital camera might contain the date/time and camera settings such as shutter speed Cameras with GPS capability can also store the exact coordinates of where the image was taken.

9. Uses of metadata Describe the file e.g. song title and artist in an MP3 file Information retrieval e.g. date/time stamp on JPEG files Ownership and rights management e.g. to stop files being copied

11. Geo Tagging Process of adding geographical identification metadata to digital media files such as a photograph or video http://www.youtube.com/watch?v=mWSFj1-L01Q&feature=related Use a device with a built-in GPS Add on GPS device Use a separate hand held GPS device and synchronize images and GPS tracking information Manually add location information (e.g. postcode)

12. Can you think of any problems with using Geo Tagging ? Most smartphones with GPS capability automatically geotag photographs. Is this a problem if you are sharing your photos online…?
