11. How OSM represents data in GIS Terms: Nodes / Ways / Relations Key / Value pairs TagInfo
12. Geographic Information is represented as: Nodes Point Ways Line Closed Line Area (Polygon) eg. Roundabouts Relations Multi (Point / Line / Polygon) eg. Bus Routes / Inner Rings
13. Tagging: Key / Value Pairs
14. Tagging: Key / Value Pairs
15. Motorway National Primary National Secondary Regional Local Primary Access Tagging: International Standards / Local Implementations
16. Tagging: Key / Value Pairs
17. Tagging: Oversight, not moderation
18. Tagging: Oversight, not moderation
19. Consuming: Tiles, Files and API’s: The OSM ‘Stack’ Tiles – your own and/or others Files – Downloads, Databases API’s – OverPass Turbo
20. Edit Store Render Consume Store Analyse
21. Tiles

26. MapInfo - .xml and .TAB files
27. Why make your own? Tile Usage Policy You’re in control: Design and Content Need tiles in EPSG:27700? 29903? Having OSM Data in a Database enables a lot of things You will learn a lot

30. Entire Planet downloadable (~500GB uncompressed) planet.openstreetmap.org
31. Processed data downloads & services www.geofabrik.de
32. download.geofabrik.de Including pre-configured Shapefiles (reduced featureset)
37. API's
43. Extract Raw Data – Embedded in a map <div> on a web page map.addLayers([ make_layer("http://overpass-api.de/api/interpreter?data= node[amenity=pub](bbox);out+skel; (way[amenity=pub](bbox);node(w););out+skel;", “Blue") ]);

45. What can you do for OSM? Talk to the community. Provide ( free) data if possible: • Road classifications. • Speed limits. • etc
46. Next OSM Meetup: Dublin, Sat 8th March: www.tog.ie
47. Some 'Takeaways‘ License Check obligations if mixing data Data Model Area / Multipolygon handling is complex Usage Policies Desktop prob not an issue. Server, web different Build Your Own No apt-get install tileserver Yet Shapefiles Easy, not complete Postgis Starting point for many possibilities Data APIs Great for snapshots in geojson or POI webpages Data vs Services Is OSM commoditising data? Is that bad?
