  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
