TRANSCRIPT
Starter• From you revision check list, identify
the 3 items you feel least confident in.
• Write each topic on a separate post-it and add it to the whiteboard.
Learning Objective
• Understand what GPS is and the different ways in which it can be used in our daily lives
• Understand how to approach exam questions to achieve the maximum marks.
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 callsbut now include cameras, music players, surfing the internet, watching videos and GPS.
Global Positioning System
Uses distance measurements
from 3 satellites to work out the user position.
Satellite-based
navigation system
24 satellites
GPS receiver compares time
signal transmitted by satellite with
time received
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
GPS Receivers
Geocaching

•Outdoor treasure hunting game
•Players locate hidden containers call geocaches using GPS enabled devices
•Share their experiences online
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.
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
Geo Tagging
• Process of adding geographical identification metadata to digital media files such as a photograph or video

•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)
• 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…?
