Addressing Adds Up
Dr. Tim De Troye, GISPGIS Coordinator, South Carolina
Do the Math
0+0 = 1???$0 Budget + 0 Additional Positions =
1 State Address Points Layer
With no budget and no additional positions – how can you do this?
Leverage Relationships
• Build partnerships with local government• Takes time, but it’s worth it’s weight in gold• Much less expensive to spend time building
relationships than to recreate/purchase data
How Do You Get Them To Say Yes
• Communicate in language decision makers understand: happy citizens = happy voters
• Provide concrete examples on how the data will be used
Who Does the Work?
• Counties create address points• State GIS Coordinator builds/maintains
relationships and acquires updates
Who Does the Work?
• Dept. of Health and Environmental Control processes the data – find a group where it will serve their core business needs
• Data made available to state agencies needing it
Getting the Data
• Ask nicely, ask often … but not too often• Recognize data sharing by the county is doing
you a favor• Always say thank you, even if the file is
incomplete or corrupt
Getting the Data
• Never ask the county to do anything more than absolutely necessary – e.g. just email me the file
• Field structure, merging data – automate with– ESRI’s Data Interoperability extension – Model Builder
First Time Acquisition
• Examine data – many different “flavors” of address points:– GPS on doorstep or mailbox– Photo revised points– Automatically generated points along roads– Parcel centroids
• Various field structures
Time Involved
• First time – examine data, set up automated tools to process address points – several hours per county
• Data refresh – straight forward – repair field structure if necessary and run automated tools – as fast at ten minutes
Follow Up
• Provide feedback to counties – never critical• Get updates and process• Provide lists of uses and agencies using their
data
Next Steps
• Set up data replication for counties with ArcGIS server (and willing IT departments)
• Set up Microsoft Scheduler with “zip and ship” scripts for other counties – automate update process for data acquisition
Next Steps
• Set up data replication across state agencies• Assist counties with no address points, as time
becomes available• Publicize when assistance is given to the
counties and “victories” of data use
