3. What is GPS? The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. GPS uses these "man-made stars" as reference points to calculate positions accurate to a matter of meters. In a sense it's like giving every square meter on the planet a unique address. These days GPS is finding its way into cars, boats, planes, construction equipment, movie making gear, farm machinery, even laptop computers.

4. Why use GIS? Navigation and positioning are crucial to so many activities and yet the process has always been quite cumbersome. GPS makes it simple. Enhance fieldwork and outdoor education. To introduce new ICT technology (links to the world of work too.) Enhance the accuracy and credibility of geographical fieldwork. Bring maps and aerial photographs to life. Essential safety and navigation aid (never get lost on Dartmoor again!) Opportunities for fun educational activities, for example treasure hunting. Cross-curricular links with maths science and PE.

5. How does a GPS unit work? A basic handheld GPS should allow you to do the following: Fix a position using a variety of co-ordinate systems (latitude and longitude and British OS grid at the very least) Navigate along a set route. Record speed and distance data. Find a fixed point. Link to a PDA or computer to allowing the import and export of GPS data. which can then be analysed and mapped. Interact with a digital map or aerial photograph, for example Memory Map.Memory Map.

7. How do I use the GPS data? Some digital map programs like Anquet and Memory Map will communicate directly with your GPS. There are several websites that will display your GPS waypoints and tracks. Options include Google Earth files, interactive maps, spectacular animations and coloured graphs. In order to make use of these services you need to be able to export data from your GPS. A third party application like Easy GPS is required to exchange data with a computer. GPS data is usually saved in.gpx format, and files of this type can be read by websites such as GPS Visualizer and Magnalox.Easy GPSGPS VisualizerMagnalox
