The Explosion of Geodata. A presentation about the abundance of geodata that has recently become openly available, where it has come from, and what we might be able to do with it. Presented at WhereCampEU, London, 2010.

1. The Explosion of Geodata Ben Dowling WhereCampEU 2010

2. Loads of Data! There is so much geodata available now. Where has it all come from?

4. Data.gov.uk

5. Open street map

6. What about the rest? The “explosion” though has come from crowdsourced geo-tagged data

7. We know where you are! With automatic location detection actions can be geo-tagged without requiring any effort from the user.

9. Base station triangulation

10. WiFi positioning (SkyHook)

12. FireEagle

13. WiFi (Skyhook)

14. W3C Geolocation

16. POIs (Gowalla, FourSquare, Yelp!, Qype)

17. Photos (Flickr)

18. Status updates (Twitter)

20. Smartphone improvements (better battery life)

23. We can geo-tag everything!

24. Where is this data? There is lots of geo-tagged data. How can you get at it?

26. Qype

27. FourSquare

28. Yahoo! Geo

29. Twitter

30. Flickr

31. Loads of APIs There has also been an explosion of services, so accessing all available information for a given location could require communicating with 10 different APIs!

33. GeoAPI

34. What to do with all the data? There is lots of geo-tagged data. What interesting things can we do with it?

36. POIs around you

37. Recommend nearby places

38. Give you directions

40. Automatic location detection is relatively new

41. The most interesting and useful applications have yet to be realised
