Agenda:

• Introductions [everyone, 10 seconds each]
• Guest speaker: Pete Warden
• How do we get more PIN codes mapped at http://pincode.datameet.org/
• Understanding OpenHeatMap
• Recording of the talk is available

Summary:

• We’ll go for bulk geo-coding as opposed to crowd-sourcing
• We’ll bulk source addresses. Please add any other sources you can think of
• The Postal College’s list of post offices
• Branch lists from banks such as SBI, or organisations like BSNL
• Telephone directories
• We’ll run them through Yahoo’s Placefinder, which is liberal in API limits and in licensing
• We’ll create Voronoi treemaps out of those (ideally as OpenStreetMap XML files)

Linked mentioned during the meet:

• http://developer.yahoo.com/geo/placefinder/ geocodes addresses liberally
• http://en.wikipedia.org/wiki/Voronoi_diagram is an explanation of Voronoi treemaps
• http://www.ptcmysore.gov.in/Publication.aspx has the official list of PIN codes. This will be available to us soon, but it does not have the data geo-coded
• http://mapstore.mapmyindia.com/pincode.html have geocoded data, but not for open use
