1. Speaker : Alexey Zinoviev
Android Geo Apps: In Soviet Russia
latitude and longitude find you

2. About
● I am a scientist. I’m interested graph theory, machine
learning, traffic-jam prediction, and big data algorithms.
● I'm also a programmer, so I'm interested in NoSQL databases,
Java, JavaScript, Android, MongoDB, Cassandra, Hadoop,
MapReduce, metaprogramming, reflection.
● And I’m a huge fan of GEO APIs (e.g., Maps APIs)

3. Introduction

4. Some maps are extremely old

5. Some maps are inaccurate

6. Some maps are used in games

7. And, of course, some maps are realistic

8. ● Geo applications are a specific
type
● Maps are optional
● Geo content in your app
● There’s a mobile aspect
Geo apps

9. Critical points

10. Localizing Content

11. Managing Digital Rights

12. Targeting Advertising

13. Data sources

14. ● Cell of Origin : finds location by
CellID
● Time of Arrival (TOA)
● Observed Time Difference (OTD)
● A-GPS : starts from base stations
LBS (Location Based Services)

15. ● GPS guzzles battery power
● GPS is often inaccurate
● People active in more than 10
times
Why LBS?

16. Maps

17. The Maps Family
Let's map
everything
on the map

18. ● Convenient controls (zoom)
● Geocoding
● Routing
● Layers
● Gestures
● Showing traffic jams and public
transport (optional)
Opportunities of Respectable API

19. ● v2 with 3D rendering
● Gesture control
● Best support and documentation
● Heatmap & clustering
● Simple integration with location API
Google Maps

20. ● Excellent coverage in Russia
● More attractive on iOS
● No direct geocoding
● Development was stopped
● No special limits
● 25,000 geocoding requests per day
Yandex Map Kit

21. ● Data from OpenStreetMaps
● Best coverage in the world
● Development by community
● No routing & traffic jams
● Tiles from MapQuest + OpenLayers
● Fork & control code :)
OsmDroid

22. ● This SDK was designed to work with
Android 2.x devices
● Best photos from space
● Excellent coverage in the U.S.
● Supports geocoding, reverse
geocoding, and routing
Bing Maps SDK

23. If you developing a project for...
● a U.S. company - Bing Maps
● a transnational company - Google Maps
● a Russian company, or one in in the former U.S.S.R. -
YandexMapKit
● OpenSource with special tiles - iOS maps with overrided tiles
MapQuest + OpenLayers
● OpenSource with its own data - OsmDroid
● … just to play - NokiaMaps

24. Geo Technologies

25. ● Latitude & longitude
● Latitude is y, longitude is x
● But it looks like this: (y, x)
● To indicate the cities, regions and
countries you need diffirent
coordinate precision
● Spherical geometry
Latitude and longitude

26. Mercator Projection

28. Data, People & Revenue

29. People

30. ● Popular commercial sites pay for
usage
● Limits
● Google Maps for business
● AdMob integration
● Time in app
Google’s profit

31. ● Media content with geolabel
● Places, addresses, organizations
● Wiki
● Type of activity
● Individual tracking
● Purchases
Data

32. Analyze it!

33. Popular Cases

34. Checking in

35. Local trade

36. Next generation of games

37. Local deals and offers

38. Publishing and distributing
content

39. Journalism

40. In conclusion
● Don’t overlocalize
● End to real privacy
● Steps to real life
