3. History of Virtual Addressing System
Establishing Geographic Location
Physical Addressing Points from GRIC GIS to MapCom using latitude/longitude coordinates.
seven telephone exchanges - (215)-10000, (315)-40000, (562)-20000, (550)-60000…etc.
A physical address point is assigned the next sequential 5-digit number available for the exchange.
Physical Addressing Points from GRIC GIS are imported into MapCom using latitude/longitude coordinates.
There are seven exchanges that have a specific range of numbers to assign from; , , , …etc.
A physical address point is then assigned the next sequential 5-digit number available for the exchange.

5. History of Physical Addressing
Structures were located by looking for white houses with blue cars in the front yard.

7. Master Street Address Guide (MSAG)
Is the official record of valid streets, thoroughfares, house numbers and communities within the jurisdiction.
Associates the proper Police/Fire/Medical responders to specific addresses.
Acts as the first point of quality control for 911 database content.
Provides proper routing of 911 calls placed from each address to the appropriate PSAP.
The MSAG is a listing of all the road names and address ranges within a given area.

9. 5 digit conversion into Physical Address
Possibly add phone and cad screen

10. Establishing Master Street Address Guide (MSAG) with Physical Addressing GIS issues
No Physical Addressing
5000 Physical Addresses assigned
Structures requiring electrical services
Public outreach
300 New homes

11. Establishing Master Street Address Guide (MSAG) with Physical Addressing – GIS Issues
New roads created
No Communication with stakeholders
Construction company issues
No verification of addresses
Departments and utilities Construction company creating access road without permission from land owners

12. Issues with being compatible with NG 9-1-1
GRIC MSAG at Gila River Telecommunication Inc. (GRTI)
Records are transmitted daily using a Service Order, this is required to have a 5 digit E911 number assigned, and a physical address is verified with GIS
GRTI sets up service to the home and GPS’s in a point for the 5 digit number.
The customers phone number, name and five digit “E-911” ID are exported to the Public Safety Answering Point (PSAP) from the 911 database.
A 5 digit number is still being used although the physical address is now being attached to the 5 digit number.

13. Issues with being compatible with NG 9-1-1
Address Ranges
Combine Road segments
Break Road segments
Address ranges added
Ran the Address Locator
MSAG Spread Sheet
GIS put the road segments in the MSAG Spread Sheet
Ran a verification on the Spread Sheet
GIS turned the Spread Sheet over to PSAP
Combine road segments – reason the road centerlines were broken in odd places example at village boundaries we had to combine all road center lines and the break the where NENA required it. Address Locater told us where an address was not accounted for in the road address ranges. We made it to 100% accuracies
Spreadsheet comparison is to check for issues with data

14. NextGen 9-1-1 Demands on GIS
GIS map data and accurate location information is a core component for NG9-1-1.
A quality GIS map data set is essential for:
Identifying locations of callers
Routing calls based on geography to the proper responding PSAP
Generating routes to emergency situations

15. Both! We must work together!
Who’s Responsible??
PSAP or GIS?
Both! We must work together!

9-1-1

16. GIS Needs to understand 9-1-1
Public safety functions
Terminology such as rebidding
 Accuracy
Spatial
Attribute
Attribute standards
Postal (NENA Standards)
 Time issue – urgency
 Need to understand “call affecting”
 Not OK to wait – done yesterday

17. 9-1-1 Needs to Understand GIS
Understand the functions
GIS is more than “map”
Each function has different GIS requirements
Understand what you are asking for
Understand base terminology
Understand function they are discussing – such as AVL
General GIS functions are not life and death

18. Data Quality Control Inconsistencies within the MSAG
Affects the how the calls are routed
Quality Control assures the all properly located
Inconsistencies within the MSAG could translate into issues with the ALI data, how the call is routed, and could prevent a call from being properly located on the map.

19. Data Quality Control Methods
What happens with the E911 Number with the new MSAG?
The E911 # does not go away
It will be used to verify address points
CAD Accuracy
Monthly locations checks
Callers using improper addresses
Call takers entering incorrect locations
