2. Mission Statement: To facilitate a statewide program that promotes collaboration on Roadway data, improves its quality and quantity, directly support E911, and supports the needs of the State of Arizona
Goals:
Provide an easy to use transactional data update tool through AZGEO
Provide feedback and facilitated communication that addresses data quality
Build on existing workflows as to not create a new workflow and reduce the number of steps (actions) that are required now
Produce a statewide address data layer that is build from the combined E911 data providers for a seamless road network with addressing.
Collaborate with all statewide partners to align goals and objectives whenever possible.
Wherever possible expand the State business capacity; i.e. a Statewide Geocoder

3. Data Collection: Supply Chain Patterns Identified
Local governments supply geospatial road data to the DOT
A third party (non-DOT, and potentially non-government) creates statewide data and supplies it to the DOT
A hybrid approach exists, whereby the state gathers as much as possible from a non-DOT aggregator (e.g., a regional agency or state clearinghouse) and then obtains the rest from locals.
The DOT compiles all the data itself
Source: FHWA Geospatial Representation Study
As we interviewed agencies about local road data collection, the various supply chain patterns began to emerge, and it became clear that understanding these patterns was a key part of understanding the collection and compilation of all roads data…

4. Principled Approach
Principles for selecting the best data supply chain pattern
Minimal impact to local data providers
Build on existing work activities
Demonstrate a return on investment
Build trust

5. Supply Chain Pattern #1
State
DOT
County
City
MPO
Federal
Land Agency
Private
Land
Owner
Local governments supply geospatial road data to the DOT
Benefits
Challenges
Opportunities
Getting data directly from those that know it best leads to highest quality
NOTE: Federal roads to be sourced directly by FHWA in the future, and made available to State DOTs
State DOT is responsible for data compilation and edge-matching
Difficult to maintain and update
Can be challenging working with larger cities/counties
Automate previously manual efforts
Sustainability
Diversified knowledge pool
Benefit from unfunded mandates
The DOT collects and assembles (conflates) centerline data from multiple organizations having jurisdictional responsibility over some set of roads and who independently manage local geospatial data resources.
Interoperability can be an issue, either dealt with by the locals (i.e. by meeting state requirements) or by the DOT (post-collection as-needed data manipulation and standardization)

6. ADOT’s Take on Data Supply Chains
WHERE IS MY DATA MAN?!!
WHERE IS MY DATA?!

7. ADOT’s Take on Data Supply Chains

8. ADOT’s Take on Data Supply Chains
Education
Linear Referencing (how hard can that be?)
Why we chose E911?

9. ADOT’s Take on Data Supply Chains
Obtaining local agency participation
Define the program
Identify components
Develop agreements
Foster a culture of continuous review

10. ADOT’s Take on Data Supply Chains
Web Repositories and Interfaces
Web Map Feedback
Engage local agencies
Include locals where ever possible
Build off of or with existing programs
NG 911
Broadband
Etc.
AZGEO
Partnership with State an Local agencies
Data passes through the clearinghouse and is distributed

11. ADOT’s Take on Data Supply Chains
Partnering with other agencies
Leverage infrastructure already built
Find Champions in every agency

12. ADOT’s Take on Data Supply Chains
Offer something in return

13. ADOT’s Take on Data Supply Chains
Benefits to Participants
Linear Referencing System
Regional State National Layers
Quality Assurance/Control
Edge-matching
Conflated & Condensed Output
Minimize Resource Requirements
Addresses /Attributes as Events
Metrics on GIS Responsiveness
