  • 1. The GeoCoding Revolution Richard Cantwell richard.cantwell@gamma.ie www.gamma.ie GeoDATA 2012
  • 2. The Art (or Science) of converting an address to a point on a map GeoDATA 2012
  • 3. GeoDATA 2012
  • 4. It isnt uncommon for neighbours along a street to write theiraddresses differently:56 Woodbrook Sq.,Castleknock,Dublin 1542 Woodbrook Sq.,Diswellstown Rd.,Clonsilla,Dublin 1534 Woodbrook Sq.,Carpenterstown,Dublin 15 GeoDATA 2012

  • 10. Fast, Simple, Accurate.. GeoDATA 2012.. Choose Two.
  • 11. Less than 10% of users will make a second attempt GeoDATA 2012Source: Public facing GeoCoding system usage metrics
  • 12. Know what you’re measuring GeoDATA 2012Purpose and Fitness of Use
  • 13. Match Confidence GeoDATA 2012Scale & Location
  • 14. Know what you’re measuring GeoDATA 2012Sample Return, with multiple Match Levels.
  • 15. Impose Order on Freeform Data.. GeoDATA 2012.. After time of capture.
  • 16. Some “Do’s and Donts” • Do expect a variety of address formats and contents, even for the same address point. • Don’t argue with the users about the one they use. • Do anticipate that non-unique addresses will be common. • Do trade off address process completeness for speed and clarity. • Do know what level of match you need: building level, county level etc. • Do record the match level for each address. • Do capture addresses in free form, sort out structure later. • Don’t let your back-end IT systems determine how you store an address.

  • 45. Key points:Ongoing developments in data and systems mean it is now possibleto batch geocode in desktop GIS with acceptable match rates.Interactive processing is recommended however, as it significantlyimproves the end result.Postcodes are coming, they represent a major opportunity to widenthe remit of GIS Managers.
