  14. 14. Know what you’re measuring GeoDATA 2012Sample Return, with multiple Match Levels.
  15. 15. Impose Order on Freeform Data.. GeoDATA 2012.. After time of capture.
  16. 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. 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.

  54. 54. Key Points: • Data Protection and Privacy concerns are paramount. • The range and depth of available spatial data is exploding. • New systems and platforms to address these are available. GeoDATA 2012
  55. 55. 2012 is going to be a revolutionary year: • Advances in GeoCoding. • Postcodes are coming. • New datasets and sources of data. • New technologies.Mean that this year has huge opportunities for GIS Managers. GeoDATA 2012
