Utah Statewide Address Point Discussion:Background

12/14/2010

Background– FGDC Transportation Grant Work Group

• Focus on Address Points

– Broadband Grant• Significant address point funding (Potential for grants

to local government?• Cadastral Grant Project as model• Fund plan for development and sharing?• Partially fund data creation?

• Current:– ESRI locators– Custom Geocoding Web Service

• Range-based location lookup using Zip Code as zone

• Planned:• Web service enhancements

– Multiple source data options» Points, Centerlines, Delivery Points (PO Boxes), Route/Milepost

– Zone = Addressing System (ws will map input zips, cities to AS)

• ESRI ‘add-in’ to use web service

Finding Addresses

Current Statewide Address Location Data/Service Users/Needs:

• Regional 911 Dispatch• Homeland Security• Blue Stakes• Tax Commission (Mobile Phone Sales Taxes)• Lt Governor, Statewide Registered Voter Database (aka HAVA,

used for precinct assignment)• UDOT Crash Analysis• One Stop Business Registration• Broadband Project• Salt Lake Urban Areas Security Initiative• Others

Potentially Large Opportunities:

• Streamlined Sales Tax (Point of Delivery sales tax assignment)

• Verification of Addresses (Registration, Licensing, Fraud Prevention, etc)

• 2020 Census• Etc, Etc.

Address and Address Point Resources:

• County Mailing Lists• 911 Calls?• Registered Voters• Drivers License• State Tax Commission• Other State databases• Existing Local Address Points• County Parcel Records• Existing Local Address Point Data

Known or Believed to have Address Points:

• Carbon Co.• Daggett Co.• Duchesne Co. (partial)• Piute Co.• Sandy City• Sevier Co.• Tooele Co.• Wasatch Co.• Wayne Co.• Others??

Address and Address Point Resources (cont.):

• County Parcel Polygons in SGID– Property Address is required by state statute– Variety of Overall and Address Attribute

Completeness

Address and Address Point Resources (cont.):

• Proposal: Basic Address Point Geodatabase Data Model (v0.1)

http://gis.utah.gov/addressing-standards/proposal-basic-address-point-data-model-v0-1

Input Parcels

Resulting Address Points

Address and Address Point Resources (cont.):

• SGID Addressing System Polygons– Grid polygons for

address systems in Utah

• QC Resource

Challenges• Local Government Participation

– ‘Selling’ importance– Different Starting Points

• State-level Utilization• Data Creation

– Standardizing Data– Balancing Automated Efficiency vs. Manual

Accuracy– Technical Assistance– Accommodating Different Needs

• Update Schedule?

Other Considerations:• Reverse 911 calls to VOIP and mobile customers;

AEDs locations, etc– Requires address registration with proper authority…one

statewide app would make process easier?• Collect Once address application

– New address point can be shared as soon as the plat is recorded

– Report a problem allows interactive re-placement of address point

– Crowd sourcing, allow anyone to use this app in background and retrieve their data via API

• Public domain dataset as result
