NG9-1-1 GIS Data Provisioning and Synchronization Project

This project aims to provide NENA-compliant GIS data for NG9-1-1, synchronize MSAG and ALI with GIS, and ensure accurate routing of emergency calls. It involves data acquisition, software tools, training, and iterative processes. Potential risks and next steps are discussed.

Presentation Transcript

  1. Agenda • Where are we now? • What problems have we seen? • Project Artifacts • Project Timeline • Pilot Findings • PSAP Boundary Discussion • Next Steps

  2. Potential RisksRecap from 2019-02-27 Meeting • Delays in receiving data • Incorrect data format • Engagement • Education

  3. Project DeliverablesRecap from 2019-02-27 Meeting • Provide software tools facilitating data import, quality assurance and local editing.   • Synchronize MSAG, ALI, GIS data and PSAP boundaries. • Support an iterative process to create a NENA-compliant GIS data set and a seamless statewide ECRF PSAP polygon layer. • Ensure ALI records can be geospatially routed to the correct PSAP in a NG9-1-1 environment. • Exceed project expectations.

  4. Next StepsRecap from 2019-02-27 Meeting • Receive contact information • Set up SFTP accounts • Data acquisition • Schedule remote install of software • Schedule training sessions • Cal NENA Conference

  5. Schedule

  6. Project Schedule

  7. Pilot Schedule

  8. Data Acquisition - Pilot

  9. Format Requirements • Road Centerlines • Street Names Elements, Address Range, Community Field • PSAP Boundaries • Unique Identification Number • ALI • NENA 2.1 format • MSAG • NENA 2.1 format

  10. Data Review & Requirements • Mandatory Datasets • Road Centerline Layer • PSAP Boundary Polygons • ALI • MSAG • Recommended Datasets • Address Point Layer • Emergency Service Zones • County Boundary • Municipal Boundaries

  11. NG9-1-1 Road Centerlines – GIS Data ModelData Gap Analysis and Correction

  12. MSAG Shadow Copy

  13. Simple vs Complex Complex Simple • Data in MSAG but not in GIS • GIS data has provided more than one match possibility. • No Comm Value on GIS data • Abbreviated MSAG Community Values • Parsing  • MSAG Not containing ST_Type

  14. Refinement Process No Matches Matching Name and Range Only Matching Name Only Matching Name, Range, and Boundary

  15. Put the MSAG on the MAP!

  16. Internal Checks (Data Consistency)

  17. Internal Checks • QC/QA checks within a data layer • Examples of Internal QC’s • Unique ID check • Null Geometry  • Duplicate Geometry  • Overlap in an Address Range  • Road not intersected • Are Mandatory fields populated? • Polygon gaps and overlaps

  18. Internal Checks (Data Consistency)

  19. Data Modification (Data Conforming)

  20. External Checks (Data Synchronization)

  21. External Checks • QA/QC checks between layers • Data Synchronization • MSAG compared to GIS road centerlines and ESZ/PSAP. • ALI compared to Addresses, Road Centerlines and ESZ/PSAP. • Important part of NG9-1-1 • Prevents fallout and ambiguity • Proactive checks to determine where a caller will be transferred from one PSAP to another or default routed.

  22. Importance of Address Points in NG9-1-1

  23. Discrepancy Training • Discrepancies • Phased approach • Discrepancy training • Webinar • Video • Call support

  24. Data Testing and Remediation • Discrepancies provided to user • Update datasets • Work through Matrix • Iterative approach

  25. Merced County Data Review • Q&A • GIS Data & QC Review • Delivery files and documentation • Match Percentages

  26. Matrix review

  27. QC Tracking

  28. Group Tracking

  29. NENA Standards • [NENA] “NG9-1-1 standards are intended to provide common and mutually-understood means for Public Safety Answering Points (PSAPs) to exchange 9-1-1 call location information” – NENA-STA-004.1.1

  30. NENA Standards • Project Focus • Provisioning and Maintenance of GIS data to ECRFs and LVFs • NENA STA-005.1.1-2017 • E9-1-1 Data Exchange Formats • NENA STA-015.10-2018 • Synchronizing MSAG and ALI with GIS • NENA INF-71-501.2009 • NG9-1-1 GIS Data Model • NENA STA-006.1-2018 • Civic Location Data Exchange Format (CLDXF) • NENA STA-004.1-2014

  31. Provisioning Standards

  32. Data Formats for E9-1-1 Data Exchange & GIS Mapping

  33. Synchronizing GIS with MSAG and ALI 98%

  34. How do you determine 98%? What do you do to get there?

  35. NG9-1-1 GIS Data Model

  36. Civic Location Data eXchange Format (CLDXF)

  37. Civic Location Data eXchange Format (CLDXF) • CLDXF is... • A standard for exchanging information • A standard produced by a wide audience to promote interoperability • CLDXF is NOT • A standard for defining the int information's content • A set of rules for maintaining GIS data
