The Do’s and Don’ts of Irish Addressing — Presentation Transcript

The Do’s and Don’ts of Irish Addressing Richard Cantwell [email_address] www.gamma.ie

# 1 DO: Be prepared for many variations on the same address, and don't argue with users * about the one they use * Users, Customers, Citizens..

It isn't uncommon for neighbours along a street to write their addresses differently: 56 Woodbrook Sq., Castleknock, Dublin 15 42 Woodbrook Sq., Diswellstown Rd Clonsilla, Dublin 15 34 Woodbrook Sq., Carpenterstown, Dublin 15

GeoDirectory www.geodirectory.ie

Porterstown? OSi – Dublin Streets

Porterstown? Microsoft Bing

Porterstown? OpenStreetMap

Porterstown? Google Maps

Porterstown? OSi Discovery Series

www.openstreetmap.org A Rural Example

Sample Townland Return www.geodirectory.ie

#2 DON’T: Force users * to use “standardised” An Post addresses * Users, Customers, Citizens..

Incompatible Aims? Need accurate verified location (GeoDirectory) But Also Need to preserve vanity elements

Note: Misspelling Entered address. Note: doesn’t include ‘Millfarm’ Confirm against ‘Real World’ Address – ‘ This is what we have matched you to’ Final Confirmed Address. Example Process

#3 DO: Know the level of ‘address match’ you need. Use this to optimise the capture process.

Know what you’re measuring Purpose and Fitness of Use

Scale Match Confidence Scale & Location

Know what you’re measuring Sample Return, with multiple Match Levels.

#4 DO: Consider unmatched parts of the address

1894 – ‘It is a very sad thing that nowadays there is so little useless information’

http://sertit.u-strasbg.fr/SITE_RMS/2009/18_rms_irlande_2009/18_rms_irlande_2009.html Unmatched Address Elements can contain Important Information

#5 DO: Trade off address process "completeness" for speed and clarity

Fast, Simple, Accurate.. .. Choose Two.

Less than 10% of users will make a second attempt Source: AutoAddress usage metrics

#6 DON’T: Trap users in an iterative hell

Avoid Endless Loops dim x as integer do until x > 5 x = 1 x = x + 1 loop

#7 DO: Capture addresses ‘freeform’ and deal with structure afterwards

Impose Order on Freeform Data After time of capture.

#8 DON’T: Let your back-end IT systems determine how you store an address

What is the correct address anyway? http://flickr.com/photos/49889874@N05/5579424951

"We will use An Post standard Addresses because at least we can refer back to some standard"

“ We will use the address from the utilities bill since this proves the person lives there" http://flickr.com/photos/genista/4610201083

"We have a large database of our own real world addresses - we can just use that - they are deliverable and we could see those as a standard too"

"We don't need a real address – just something which fits the structure of our current system" http://www.dilbert.com

#9 DO: Recognise the value of locational information

“ It sort of makes you stop and think, doesn’t it?” http://bit.ly/pU7UWY Cleaned and Geocoded Address data has wide ranging value

Breaking down the Data Silos http://bit.ly/nQnUvK

#10 DO: Prepare for forthcoming changes

Postcodes? An Unknown Unknown ? ? ? ? ?

Small Areas Data Coming to a Map near you in 2012

New Kinds of Address Data & Platforms FourSquare data (via GeoRSS) on a map from http://www.dotspotting.org

Google Fusion Tables http://www.gamma.ie/CSO/Population2006-2011.html
