Yesterday I gave a talk to the British Computer Society about openstreetmap.
The topics I talked about were
- OpenStreetMap purpose and premise – Comparison with wikipedia, graph showing the long tail nature of the community
- Data structures – Nodes, Ways ,Tags and their XML representations
- Editor demo – Quick demo of adding a road and a POI in JOSM
- OpenStreetMap servers and architecture – Component diagram, UCL hosting details, and the OpenStreetMap foundation
- Rendering and map displays – OpenLayers, Tile serving/hosting challenge, Mapnik toolchains, and other renderers
- The license – Attribution. Sharealike. The spirit of the license, and change to the Open Data Commons
That was all well received. Of course OpenStreetMap is a topic I have tonnes to say about, and I as prepared I got a bit carried away, and came up with 146 information packed slides. I had quite a long time to talk, but what with JOSM demonstrations and video interlude, it was clear I’d overrun by a mile, so I stopped at a convenient juncture part way through.
Other topics I didn’t cover include: Imports, Yahoo imagery, Landsat & NPE, Armchair mapping, a demonstration of photo mapping in JOSM, Mapping Parties, Developer community, and details of how to get involved. Enough material for a part II some time perhaps!
