In the spring of this year I have mapped the vast majority (>95%) of shops and retail areas in Nottingham, the 8th largest retail centre in the UK, serving a market of around 1 million people. In addition I have repeated the exercise for a Maidenhead a town of 70,000 which is only a local shopping centre. Comprehensive mapping of retail outlets allows a more rigorous analysis of OSM data, with significant implications for how we should collect and map data for shops. These include: better support from mapping tools (particularly for mapping change), defining a usable classification for retail areas, and improving consistency in tagging. These need to be cross-checked for different countries, so I hope this provokes extensive contributions from other participants.

– Pub/Bar/Nightclub

outlets
• Usually current

months

5. Mapping
Process
• Extensive not
Intensive.
• Comprehensive
• Driven by external
data (City Open Data).
• Limited mapping
targets

6. Mapping
• Photo Surveying
– Building Line
– Detail of Shop Front
– Limited address info
– Relies on high-quality aerial imagery
• Basic Mapping
– Initially add as nodes with ~ location
– Add Building outlines and improve location
– Transfer detail from nodes to ways
• Refinement
– Address data (mainly FHRS + interpolation)
– Add contact, opening hours etc

10. Mall
• shop=mall too generic
– Shopping Centres
– Arcades
