1. Let’s Shake on It! Providing Roadway Match Points across Multiple Jurisdictions
2. ▪ Securing internships, projects, and temporary positions to provide students with professional skills ▪ Partnerships include: • Commission on State Emergency Communications (CSEC) • Texas Natural Resources Information System (TNRIS) • Texas General Land Office (GLO) ▪ Since 2012, ACC Inc and partner organizations have funded 35 paid GIS internships valued over $340,000 ▪ Almost all of these interns have progressed to full-time employment as a GIS Professional ACC Inc ACC Incubator for Professional Skills NG 9-1-1 Roadway Match Points
3. NG 9-1-1 Geospatial Data Assessment CSEC - ACC Interlocal Cooperation Contract NG 9-1-1 Roadway Match Points
4. NG 9-1-1 Geospatial Data Assessment 50+ county reports submitted to CSEC since 2016 NG 9-1-1 Roadway Match Points

11. ▪ Question - Frame the question ▪ Inform - Explore and prepare data ▪ Analyze - Choose methods and perform analysis ▪ Decide - Examine and refine results ▪ Present - Present the analysis GIS Analytical Process Structured Approach to Solving GIS Problems NG 9-1-1 Roadway Match Points From Use the Five-Step GIS Analysis Process by S.Boden, ESRI
12. ▪ Data: PSAP Boundary Lines, Road Centerlines ▪ Reference Orthoimagery:Texas Google Imagery Service (TNRIS) ▪ Primary question: Where should the road centerline intersect the PSAP boundary line? Match Points: Framing the Question At Its Simplest, the Intersection of Two Lines NG 9-1-1 Roadway Match Points TNRIS - Google Imagery Accuracy Assessment
13. ▪ Is the Road centerline accurate at the PSAP boundary? ▪ Are PSAP boundaries coincident/clean at the roadway? ▪ What PSAP boundaries are present at the road? ▪ What is the Road name? ▪ Are Road Centerlines located near center of roadway? ▪ Which other boundaries are conceptually present at intersection? (County, RPC, ECD)? Additional Match Point Questions What Data Fields Do We Need? NG 9-1-1 Roadway Match Points
14. ▪ For PSAP boundaries at the road, three choices: a. Clean - Coincident or Single PSAP boundary b. Gap between PSAP boundaries c. Overlap of PSAP boundaries ▪ For Road centerlines at the PSAP boundaries, two choices: a. Clean - Road Centerline near center of road b. Identified - Point moved to center of road per reference orthorimagery Match Point Category Scenarios What Different Buckets Do We See with PSAPs and Road Centerlines? NG 9-1-1 Roadway Match Points
15. ▪ We presented the interim findings from the Question and Inform phase work. ▪ Proposed match point categories ▪ Proposed gap/overlap plan ▪ RPC Analysts noted some existing sets of regional match/stitch points. Client/Stakeholder Meeting Pre-Analyze Phase Exit Inflection Point NG 9-1-1 Roadway Match Points
16. ▪ Imported and explored existing match points from 5 RPCs ▪ Developed plan for conceptual duplicate points. ▪ Incorporated Statewide 911 System Road Centerlines Additional Cycle of Question/Inform Incorporating Existing Match Points Data, 911 System Road Centerlines NG 9-1-1 Roadway Match Points
17. ▪ Implement attribute domains for PSAPs, counties, RPCs, ECDs and match point categories ▪ Build initial/blank dataset, break project into RPC chunks ▪ Develop and document geoprocesses and workflow for the two primary match point workflows. Moving to the Analyze Phase Preparations NG 9-1-1 Roadway Match Points
18. Created Match Points Workflow Starting with an Intersect Analysis NG 9-1-1 Roadway Match Points
19. Imported Match Points Workflow Incorporate RPC’s Match Points, Split out Duplicates, Add Points NG 9-1-1 Roadway Match Points
20. Match Point Examples Clean PSAP Boundaries Within RPCs NG 9-1-1 Roadway Match Points
21. Match Point Examples Overlap between two PSAP and RPCs NG 9-1-1 Roadway Match Points
22. Match Points Additional Categories Being Flexible, Adjusting for Unforseen Scenarios NG 9-1-1 Roadway Match Points
23. Match Points Additional Categories Intersects Detected by ArcMap, but Not Road Crossings NG 9-1-1 Roadway Match Points
24. ▪ Merge and QC ▪ Finalize Datasets ▪ Final Match Points: 12,136 Decide Phase: Finalizing the Analysis Wrapping up our work NG 9-1-1 Roadway Match Points
25. Present Phase Drawing Conclusions from the Final Match Points Dataset NG 9-1-1 Roadway Match Points
26. ▪ Expand to Statewide Dataset Including ECD match Points ▪ Resolve Gaps and Overlaps at RPC Boundaries ▪ Resolve match Points w/Coincident Vertices, Not at Road Centers Opportunities Going Forward NG 9-1-1 Roadway Match Points
