1 MSAG Synchronization Patrick McKinney, Cumberland County

2 NENA Sync GIS Databases with MSAG & ALI On-going process of syncing MSAG & GIS datasets Recommended minimum match rate of 98% (p. 8) Differences between MSAG & Road Centerlines includes (p. 8): o Missing roads o Naming conventions of roads o Inaccurate address ranges o Incorrect MSAG Community designation Official title: NENA Information Document for Synchronizing Geographic Information System Databases with MSAG & ALI

3 MSAG & GIS Update procedures Developing standard update procedures for MSAG & CAD datasets can help reduce errors Consider using tools like Esri Attribute Assistant in workflows Possibility of managing NENA & CAD required fields simultaneously

4 Cumberland County Process 1. Export table of all possible MSAG addresses. Icons provided by flaticon.com 2. Geocode MSAG addresses; spatially join CAD municipal boundaries to mapped addresses 3. Resolve unmapped addresses; resolve mapped addresses in wrong municipality

5 MSAG Database Coordinate addressing with 33 municipalities & 2 military institutions MS SQL Server back-end with MS Access frontend for edits

6 MSAG all addresses script

7 Geocode Process 3 Locators: Road Centerlines, Address Points, and Composite Perform geocode on composite and road centerlines Address locators need to be created with the municipality as your zone/place instead of postal community zip code

8 Geocode results - Address Points - Road Centerlines

9 Unmapped MSAG Addresses Export records to table and review Update ranges in road centerlines Create address point (or commonplace) Check with municipality about existence and/or necessity of address ranges and update MSAG

10 Inconsistent Address Ranges - Address Points - Commplaces

11 Mapped MSAG addresses Goal is for addresses to geocode in assigned municipality Administration of municipal boundaries is not purvey of Counties (but we still have to deal with it for CAD) Identify which MSAG records (table) do not geocode in assigned municipality (polygon) o Spatially join CAD municipality layer to mapped addresses o Perform attribute query to find mismatched records

12 Municipal Boundary quirks - Road Centerline Geocoded Addresses - CAD Municipal Boundary - PennDOT Municipal Boundary

13 Cumberland County Process 1. Export table of all possible MSAG addresses. Icons provided by flaticon.com 2. Geocode MSAG addresses; spatially join CAD municipal boundaries to mapped addresses 3. Resolve unmapped addresses; resolve mapped addresses in wrong municipality

14 Remember the reason! crucial to providing telecommunicators the information they need to correctly verify the location of a caller and provide proper emergency response." P. 8, NENA Information Document for Synchronizing Geographic Information System Databases with MSAG & ALI

27 Boundaries Context: Boundaries used in GIS come from somewhere o Census o USGS o PennDOT o Local No designated official GIS source to use, display, update

30

31 Boundaries Often started from a source but used for other purposes o Voting o Population o Funding Allocation o Service Areas o Analysis

32

33 Boundaries Change over time Change between different sources Impact interpreted use and analysis Can fall into 2 categories o Authoritative o Functional/Administrative

34 Boundaries Authoritative (aka. Official) o Official rules and laws for the creation or change of boundaries PA Municipal Code PA Title 53 (Assessments) PA Boroughs Townships and County Code PA Boundary Change Procedures (DCED 2014) o Laws and procedures cover legal description and paper; this does not percolate into an official GIS Source

35

36 Boundaries Functional/Administrative o Created at some point in time from some source probably not updated since o Created for a specific purpose o Reused or adjusted for multiple purposes Regulation (law enforcement, zoning, land use, etc.) Voting Population (Census) Funding Allocation (taxes and grants) Service Areas (emergency or other) Tied to analysis

37

38 Boundaries NG911 Functional/Administrative o PSAP (Public Safety Answering Point) Generally considered a county boundary but can include MOU/Service agreements or extended coverage areas o ESZs (Emergency Service Zones) Police, Fire, EMS Can be municipality, parts of municipalities, specific response area, groups of tax parcels, bounded by roads or geographic features, grids, etc.

39 Boundaries Problem: no delineation procedures or standardized training for GIS maintenance o PSAP Created at some point in time from some source probably not updated since Impact: call shipping, GIS feature matching, background (basemap) alignment Solution: PennDOT County boundaries as a starting point for current year o Recognize PennDOT GIS boundary steward (already doing it) Common Geometry o Census Boundary Annexation Survey (BAS) annual update from PennDOT DCED as state official certifying source o 67 counties start with their PSAP and align coincident boundaries with PennDOT County and Municipal boundaries and adjust with other service area boundaries to create consistent PSAP o Fix road centerline info to break at coincident boundaries o Update annually for consistency with BAS and PennDOT boundaries

40

41 Boundaries Problem: no delineation procedures or standardized training for GIS maintenance o ESZs Created at some point in time from some source. Probably not coincident with neighbors boundaries, definitely not standardized in the method Impact: call shipping and dispatching, GIS feature matching, background (basemap) alignment, timely and appropriate response Solution: define the method in which ESZ boundaries are created, adjusted, maintained and do not waiver from standards o Road intersection to intersection o Tax parcels o Municipal boundaries o Defined grids (such as US National Grid) o Closest capable response not turf war or political but life saving!

52 How important are boundaries? Boundaries will make or break NG911 o Used to route calls to the correct PSAP o Used to define the appropriate responding agency and apparatus to an incident. o Used in reporting PA has 67 Counties and approximately 2,700 Township / Borough / City boundaries. All of these entities must have coincident boundaries. Any gap or overlap in these boundaries could cause a problem with NG911.

53 Process for Correcting boundaries At this point we are still determining the best practices and procedures for correcting boundary lines. However, there are some givens We know that we need to start with Municipal Boundaries. Many other datasets will be based off these initial datasets. o Streets are split by municipal boundaries. o Often times response boxes follow municipal boundaries. We know that we will need a single authoritative source to use as the NG911 State, and County Boundaries. o This could be the PennDOT s municipal boundaries. o This could also be a mixture of PennDOT and County boundaries. o Regardless, they must be synonymous.

54 Process for Correcting boundaries An option on the table would be to use PennDOT State and County boundaries while maintaining the Municipal boundaries from the County records. *** Note PennDOT has a process for updating their information as long as you have the proper documentation. Ultimately we are in this together. This communication is vital to a successful project.

55 The Next Steps Once all your Municipal Boundary issues are resolved we can move into the correction of other Boundary layers like PSAP, Fire, Police, EMS, etc. o This will take communication, cooperation and some compromising. o Review your emergency service boundaries internally and make sure they are the most effective responses possible. o Talk to your neighboring Counties and make sure your boundaries are coincident. ***Remember any gaps or overlaps will cause problems with NG911.

56 What are Gaps and Overlaps? There s been a lot of emphasis about gaps and overlaps but what does this mean in terms of the data and how does this cause problems with NG911? A gap is an area of missing data Notice the white space in the image to the right. This is a gap or an area of no data. o This could be a problem if a callers information falls within the area of the gap. So, if the X/Y coordinates of the caller, or the given address falls within this area NG911 will not know where to send the call (Municipal line gap), or not know what apparatus, (fire police, EMS gap), to send to the incident.

57 What are Gaps and Overlaps? An overlap is an area where 2 polygon zones occupy the same area. Notice the purple colored area in the image to the right. o This is equally as problematic. In this instance, NG911 still will not know which PSAP to choose, potentially sending it to the incorrect PSAP causing and causing a delay in response time. o Similarly, if this is a response zone, NG911 may select the incorrect zone sending the wrong apparatus to an incident. ***Note: These gaps and overlaps are not limited to just inter-county boundaries. Any gap or overlap, whether within your own county or between counties is an issue!

59 GIS Pros Boundary committee Convened in the summer/fall of 2016 o Reviewed many of the nuances of the boundary issues in Pennsylvania. NENA Conference in the fall of 2016 o Presentation of subcommittee findings during a scheduled session. o Information presented from a variety of sources. o Reviewed issues from background of survey delineation in PA to current issues. Boundary issues in the commonwealth are quite complex and interlocking. o Geography o Sources o Legality o Accuracy o Disputes o Conflict Resolution o Need for a Base-map o Indemnification

60 Geography Pennsylvania not part of the Public Land Survey System o USGS Info for PLSS

61 Boundary related issues Varied Sources can create conflicts o USGS o US Census Bureau o Pennsylvania DOT o Internal Research o Hybrids Legality o DCED manual Boundary Change Procedures o Section No. 2 Legal Setting State has authority o Local aggregation of information and data

62 Boundary related issues Accuracy o Detailed information in some instances o Very lacking in others o Leads to disputes o Who has the most resources & verifiable information? Disputes o Confusion results from the above factors. o Disagreements arise as to where boundary lines should fall. o Impact on jurisdictional authority & allocation of resources. Indemnification o Liability is high, agencies will not agree to indemnification, but state has the final say on boundary location? o Changes may have drastic impact. E.g. PennDOT liquid fuels calculation Even small changes may shift tens of thousands of dollars between jurisdictions over time.

63 Conflict resolution Who has the resources for the most research? o Research Utilize GIS to quickly identify conflicts. Analyze how boundary source versions differ. Identify major/minor discrepancies. Identify structures in conflict areas. Where do conflicts actually occur? Head-off problems o Goes to the courts o Mutual agreements o Costly process, no matter how one looks at it

64 Boundary solutions Need for a Base-map o Ideal solution is an agreed upon base-map o Sanctioned by the state. o All conflicts worked out in advance to head off more costly disagreements and legal problems. o NextGen 911 map a good start for a base-map. o Could it possibly evolve into something reliable and legally binding for statewide matters as to jurisdiction?

65 Tioga County boundary research project circa Detailed project, RETTEW o Identified 621 monuments related to boundaries o Extensive volume of written material o Images o Vector data deliverable Additional field resources o Monument recovery layer 68 points used for aerial photo geodetics as well. o County surveyor of record, control points from extensive library of digital survey copies. o Parcel fabric editing geodetic control & entry by way of COGO.
