  2. 2. The Power of the Image Or... 2011 “I want something like Google Maps, but using OS data”
  3. 3. The Power of the Image Overview 2011 • Where it all began • What‟s possible today • What we can learn from this • How we can create our own basemaps • ...and make these accessible
  4. 4. The Power of the Image MapQuest launched 1996 2011
  5. 5. The Power of the Image Google Maps, today 2011
  6. 6. The Power of the Image Bing Maps 2011
  7. 7. The Power of the Image Google Maps API Styled Maps 2011
  8. 8. The Power of the Image What people like / expect 2011 • „Slippy‟ map interface • Very fast drawing speeds • Drill down for more detail • High quality cartography • Multi-platform support
  9. 9. The Power of the Image Map tiles 2011
  10. 10. The Power of the Image Why use map tiles? 2011 • Pre-render for optimal performance • Reserve server resources for dynamic data • Merge tile layers on request for flexibility • Subtle cartographic effects • Accessible colour palette • Easy to use • Variety of hosting options
  11. 11. The Power of the Image Considerations 2011 • Time required to perfect cartography • Rendering process very resource hungry • Not quick to produce a completely new output • Vectors still required for small % of users performing data capture
  12. 12. The Power of the Image How will users consume maps? 2011 • Desktop mapping applications • Public facing web applications • Intranet mapping applications • Mobile (massive growth ahead)
  13. 13. The Power of the Image Why wouldn‟t you use Google? 2011 • Need more detail • Need greater accuracy • Need cartographic subtlety • Complex technology landscape • Licensing? • “I want something that looks like Google Maps, but uses OS data”
  14. 14. The Power of the Image PSMA 2011 • Public Sector Mapping Agreement • 10 year agreement • Public sector bodies in England & Wales • GB coverage, free at point of use • Allows data sharing
  15. 15. The Power of the Image PSMA products 2011 • OS MasterMap Topography Layer • OS MasterMap Integrated Transport Network • 1:10,000 raster (until 31 March 2013) • OS VectorMap Local • 1:25,000 raster • 1:50,000 raster • Code-Point • Code-Point with Polygons • OS OpenData • National Address Gazetteer

  21. 21. The Power of the Image Universal access 2011 • Support for those with a colour vision deficiency • 1 in 12 males • 1 in 100 females • Build accessibility in from outset • Avoid extra time & costs later
