How and why governments should use OpenStreetMap - Pete Lancaster - State of the Map 2013

*** Presented at State of the Map 2013 ***

Local and national governments regularly encounter issues with licences for geographical data. In the UK, Ordnance Survey licensing has thrown up numerous issues for local authorities with limited budgets wishing to easily display geographical data to their customers. Many of these issues can be easily overcome through the use of OpenStreetMap, OpenLayers and a generous helping of coffee.

This talk is intended to explain how governments can harness the power of OpenStreetMap and OpenLayers to make their data come alive quickly, and give an insight into a recent project in Warwickshire that did just that.

How and why governments should use OpenStreetMap - Pete Lancaster - State of the Map 2013

  1. 1. How And Why Governments Should Use OpenStreetMap Pete Lancaster Warwickshire County Council
  2. 2. Why on earth doesn’t every public website use OpenStreetMap?
  3. 3. Reasons I’ve heard: ● Existing contracts ● ‘Exact’ data needs to be mapped on top of ‘exact’ OS maps ● Legacy systems ● Better in-house knowledge of Google Maps, Bing, etc ● OSGB to WGS84
  4. 4. Existing contracts ● Suppliers come and go ○ That’s why most contracts are fixed lengths ● How much is your contract really worth? ○ Is a £20,000 solution, with £10,000 ongoing support really viable in 2013? Really? Really? ● Web and data analysis teams know their stuff ○ Chances are - your web team or data analysis unit are already using open alternatives, or are keen to
  5. 5. Existing contracts
  6. 6. Still a good reason?
  7. 7. ‘Exact’ data needs to be mapped on top of ‘exact’ OS maps ● How ‘exact’ is OpenStreetMap? ○ Truthfully, it varies ■ In Warwickshire, thanks to Mappa Mercia, it’s very good (and beats Google Maps for accuracy) ■ In Birmingham, it’s also very good, also thanks to Mappa Mercia ○ OpenStreetMap is as exact as the group updating it were when they mapped it ■ Warwickshire CC staff have updated OpenStreetMap (a Warwick group is currently being pulled together)
  8. 8. ‘Exact’ data needs to be mapped on top of ‘exact’ OS maps
  9. 9. Still a good reason?
  10. 10. Legacy systems ● Existing map system too ingrained to ‘break out’ of ○ I hereby challenge you to prove this ○ I also challenge you to show us how using OpenStreetMap with OpenLayers won’t save you time, effort, pain and money ● Old systems were probably good at the time they were brought in ○ Their time has passed ○ Mapping moves on - just as the rest of the world does
  11. 11. Legacy systems Plan for the future - the systems you use today won’t be the ones you use tomorrow.
  12. 12. Still a good reason?
  13. 13. Better in-house knowledge of Google Maps, Bing, etc ● Knowledge is transferable ○ Take what you know in one system, and apply it to another ● The principles are the same ○ I knew nothing about OpenLayers before I started using it - and I’ve built four mapping systems using it (to date)
  14. 14. Better in-house knowledge of Google Maps, Bing, etc *this took around three weeks of dedicated work to get it working, starting with zero knowledge and including the time it took to get the data, port it from Symfony2 to WordPress, have meetings about approaches, etc.
  15. 15. Still a good reason? * Be More Dog campaign - O2 Mobile
  16. 16. OSGB to WGS84 (or whatever format) ● You’re kidding right? ○ Think ahead - use systems that don’t force you to only display / generate data in one format ○ I can’t begin to list all of the ways to convert your data, but: ■ OpenLayers has conversions built in ■ PHP libraries exist to make the task easier for batch jobs of large datasets ■ Or just use a flexible recording and editing system that can export to different standards ● This, frankly, is just the worst excuse
  17. 17. Still a good reason?
  18. 18. So let me put it another way.
  19. 19. There is no good reason that public sites don’t use OpenStreetMap today.
  20. 20. So do it.
  21. 21. Now, how can Governments use OpenStreetMap? (if you’re, y’know, stuck for ideas…)
  22. 22. Roll a WordPress plugin for a high profile event, like an election
  23. 23. Roll a WordPress plugin for a high profile event, like an election ● Built in pieces, as part of other projects, over the course of a year ● OpenLayers and OSM were only part of it ● RaphaelJS ● Google Fusion Tables ● End product was produced completely inhouse
  24. 24. Roll a WordPress plugin for a high profile event, like an election ● Using OpenStreetMap will go down very well ○ BBC praised on the coverage during the day ○ Positive feedback received from residents before, during and after the election ● OpenLayers and Raphael examples are in abundance and will suit your project perfectly ● Google Fusion Tables can open up your data immediately
  25. 25. Roll a WordPress plugin for a high profile event, like an election ● Roughly 40% of traffic for a week (139,905 views) ● 2nd largest peak event for the site (snow disruption came first) ● Used as main visualisation tool within count centres ● Worked with OSM administrators to ensure they were aware of possible traffic spikes
  26. 26. Switch out your most popular maps for OpenStreetMap versions Country Parks Libraries
  27. 27. Switch out your most popular maps for OpenStreetMap versions
  28. 28. Switch out your most popular maps for OpenStreetMap versions ● People love the clarity ○ It’s often surprising to look at the reaction of people using a non Google or Microsoft map - they like what they see ○ The extra information on the base map (such as bus stops, car parks, etc) also goes down well ● Plus, you could just ‘roll your own’
  29. 29. Or you could just... ● Use an OpenStreetMap base as a starting point for a transport mapping project ● Map your locality’s parish / town councils and their coverage ● Create a tool to show end users how funding is apportioned between areas ● Give opened up MP expenses data real meaning
  30. 30. The world is your oyster.
