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 Build partnerships with local government Takes time, but it’s worth it’s weight in gold Takes time, but it’s worth it’s weight in gold Much less expensive to spend time building relationships than to recreate/purchase data 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 Communicate in language decision makers understand: happy citizens = happy voters Provide concrete examples on how the data will be used Provide concrete examples on how the data will be used

Who Does the Work? Counties create address points Counties create address points State GIS Coordinator builds/maintains relationships and acquires updates 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 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 Data made available to state agencies needing it

Getting the Data Ask nicely, ask often … but not too often Ask nicely, ask often … but not too often Recognize data sharing by the county is doing you a favor Recognize data sharing by the county is doing you a favor Always say thank you, even if the file is incomplete or corrupt 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 me the file Never ask the county to do anything more than absolutely necessary – e.g. just me the file Field structure, merging data – automate with Field structure, merging data – automate with – ESRI’s Data Interoperability extension – Model Builder

First Time Acquisition Examine data – many different “flavors” of address points: 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 Various field structures

Time Involved First time – examine data, set up automated tools to process address points – several hours per county 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 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 Provide feedback to counties – never critical Get updates and process Get updates and process Provide lists of uses and agencies using their data 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 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 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 Set up data replication across state agencies Assist counties with no address points, as time becomes available Assist counties with no address points, as time becomes available Publicize when assistance is given to the counties and “victories” of data use Publicize when assistance is given to the counties and “victories” of data use News Flash: State and Locals Working Together
