  2. Location-Based Systems

  3. Variables for Geo-Location • Latitude: north/south • Longitude: east/west • Heading: compass direction. Leeds Metropolitan University Faculty of Art, Environment and Technology

  4. Compass Heading • Simplistic: direction towards Northpole = 0deg. • http://airplanegroundschools.com/Navigation/ Leeds Metropolitan University Faculty of Art, Environment and Technology

  5. Different Headings • True heading: north pole as rotational axis. • Magnetic heading: is shifting – see map • Compass heading: effect of metal near compass Leeds Metropolitan University Faculty of Art, Environment and Technology

  6. Geo-Location in Software • Google Maps for mobiles: • https://developers.google.com/maps/mobile-apps • Geo-awareness in website: • http://stackoverflow.com/questions/6246064/creating-location-awareness-in-website • W3C geolocation: • http://dev.w3.org/geo/api/spec-source.html Leeds Metropolitan University Faculty of Art, Environment and Technology

  7. Static Mapping • Without JavaScript: use map as an image. • See here: • https://developers.google.com/maps/documentation/imageapis/ • Examples: • http://creativetech.inn.leedsmet.ac.uk/MWC/MapStatic1.html • http://creativetech.inn.leedsmet.ac.uk/MWC/MapStatic2.html Leeds Metropolitan University Faculty of Art, Environment and Technology

  8. Dynamic Mapping • Map changes as user moves. • Needs access to location through sensor. • Location sensors: • Outdoor: GPS. Needs view of sky. Is very precise (+- 1m). • Indoor: WiFi or phone network. Not very precise. Can be +- 50m up to +- 500m. • Updates: driven by JavaScript. Leeds Metropolitan University Faculty of Art, Environment and Technology

  9. Dynamic Mapping Examples • Examples: • http://creativetech.inn.leedsmet.ac.uk/MWC/MapDynamic1.html • http://creativetech.inn.leedsmet.ac.uk/MWC/MapDynamic2.html Leeds Metropolitan University Faculty of Art, Environment and Technology
