Slide 49: OpenStreetMap

Slide 50: §

Slide 52: Why OSM? • Geodata isn’t • Free • Open • Current • Wiki is obvious next step • It’s just fun

Slide 53: Some Quotes

Slide 54: Quote 1 “It’s absolutely possible for a bunch of smart guys with the technology we have today to capture street networks, and potentially the major roads of the UK and minor roads” Ed Parsons, ex-CTO Ordnance Survey

Slide 55: Quote 2 “If you don’t make [lower-resolution mapping data] publicly available, there will be people with their cars and GPS devices, driving around with their laptops .. They will be cataloguing every lane, and enjoying it, driving 4×4s behind your farm at the dead of night. There will, if necessary, be a grass-roots remapping.” Tim Berners-Lee

Slide 56: Quote 3 “You could have a community capability where you took the GPS data of people driving around and started to see, oh, there’s a new road that we don’t have, a new route .. And so that data eventually should just come from the community with the right software infrastructure.” Bill Gates

Slide 57: We make beautiful maps

Slide 58: ...which we give away

Slide 81: Using OSM

Slide 87: Workshops Or, Map as Party

Slide 94: Fallout

Slide 96: A-Z Norman Dennison, director of Geographers' A-Z Map Company, conﬁrms that Lye Close is a lie, which will now be removed. \"The idea is to put something on the map to protect copyright,\" he says. \"We try to put it in an area or a part of a road which would not be misleading to the ordinary person in the street. They have been put in out- of-the-way places.\"

Slide 97: Postcodes

Slide 106: EU GeoData Maket NMA I’m ignoring ex- copyright data as Price its place is very debatable OSM 100 ‘%’ ‘Quality’

Slide 110: We’ve seen this before

Slide 111: OS Market Windows Price Linux 100 ‘%’ ‘Quality’

Slide 112: OS Market Windows (Think price per feature) Price Linux 100 ‘%’ ‘Quality’

Slide 115: • Consultancy • Development • OpenStreetMapData (cleaned, nice formats) • Proprietary data, using OpenStreetMap tools (much cheaper)
