1. Emergency Service Boundaries (ESB) Program
NYS GIS Program Office

2. ESB Program Objective
Create and maintain statewide authoritative emergency service boundary databases to support E9-1-1 and NG911

3. GIS Data for E9-1-1 Required Optional Street Centerlines
Address Points
Aerial Photography
Parcels
Police, Fire, EMS boundaries
Cell Site Location / Coverage
Other reference data (schools, hospitals, mile markers, hydrology, etc)

4. GIS Data for NG9-1-1 Required Optional Address Points
Street Centerlines
Emergency Service Boundaries (ESB)
Optional
Aerial Photography
Cell Site Location / Coverage
Other reference data (schools, hospitals, mile markers, hydrology, etc)

5. ESB Program Details What Why Where When How
One master address point database for use by everyone

6. What PSAP, Police, Fire, EMS, Ambulance territories Statewide
ESZ vs ESB
NENA data standards for NG9-1-1
One master address point database for use by everyone

7. What
One master address point database for use by everyone

8. Why
Some current CAD systems need ESB GIS data for response plans – ie: Spillman, TriTech
Future NG9-1-1 depends on ESB GIS data to route calls in the ECRF and dispatch responders
Consistent, statewide NENA standard ESB datasets will the best solution for all

10. Where Albany County pilot
Gradual roll out to the rest of the state, gathering data already created, building data where necessary, based on lessons learned from pilot
One master address point database for use by everyone

11. When Program began early this year
Pilot project now with Albany Co through middle of next year
Gathering existing data from counties that have mapped their ESB
Gradually expanding the project to cover the entire state based on first two outcomes

12. How
Geocoding the MSAG, digitizing paper maps, data review with counties
One master address point database for use by everyone

13. How? Geocoding takes a street address and returns a lat/long pair
Must be in Address, City, State, Zip
MSAG Addresses are not
Hi address, Low address, Community, ESZ
How to format that as an address for geocoding?

14. How? Reformat MSAG Standardize with Google API
Hi address, Community, County, State, ESZ
Low address, Community, County, State, ESZ
Standardize with Google API
Google takes MSAG above and returns
Address, City, State, Zip, ESZ
One master address point database for use by everyone

15. How? Geocode with NYS Geocoder
Address, City, State, Zip, ESZ, Lat, Long
Create points from the Hi/Low MSAG ranges
Throw out outliers based on SD of the geographic mean
One master address point database for use by everyone

16. How? Create the ESZ by connect-the-dots
Add Police, Fire, EMS from ESZ key
Dissolve by the agency to form the ESB layers
Gives a rough outline of the ESB, but still needs manual cleanup

17. Albany County Pilot GeoCoding the MSAG
Using paper reference maps to check accuracy

19. Questions? How long will it take to finish the state?
When will my county be done?
I am updating my CAD software and need ESBs, can the state help?
How will the data be updated once completed?
