1 Red Cross Annual Appeal 2004 (2200) Locate collectors, assign streets and postcode for sorted bulk mailing

2 Built roads as single arcs using a route system Exclude roads allocated by hand Spatial join in ArcView 3.2 (avenue scripts) Lowest ID first to resolve ties Exclude allocated streets and repeat 2004 - Nearest whole street continued manual start

3 Double collector numbers 2004 (2200)2005 (4200) Do you really know your own location address?? 250 location errors, 150 had to be rung up again!

4 Geocoding AddressParse, AddressMatch SpatialOrder - Peano Curve Numbering Allocate (resources on arcs to centres and routes) ArcInfo Network Module

5 2005 - Allocate 50 houses per collector - nearest, contiguous, street segments - to pack them in where dense - to reduce the variability - to be clever, to prove that GIS…

6 Still needed to choose 1000’s of centres First pass 5 min, time halved each pass After 9 passes, still 250 “spare” collectors Allocate

7 Reduce min capacity Increase start distance Give a “second chance” Tune for dense areas

8 Rounding up and down to nearest intersection Collectors unable to stop mid-segment Many cannot, or would not, read a map

9 AML “Model Builder” 69 “Tools” in Model 500 lines of AML Adaptive iteration Output from one tool not able to be Input to next, needed low- level hacking Two days available

10 Mail-merge with a map 4000 maps/ hour, mail merge 3.5GB/1000 letters

11 “Spares” to be allocated by hand …but ran out of time Accepted fault and reprinted letters because of my postcode error

12 Collection Week Queries overwhelmed the help desk, even with maps Added myself as a collector to experience it Own street was the best part Addresses underestimate the dwellings by 30%

13 Results Analysis Amount per collector (av $76) Distance from address

14 Next Year, Version 3… 2004 increased by 50% to $150,000 2005 increased by 40% to $211,000 Collector preferences! next year… –Improve choosing collectors –Better reference layers –Spread collectors better –More time for mail-out
