Present Geocoding

Cascading – 2 Composite Locators

– SAM Address Points – NYS Address Points – Street Centerlines – Street Names – Zip Codes

Duplicate data removed from lower tier

locators

Currently searches through all locators even if

you get an address point match

NYC GeoSupport

SLIDE 21

Geocoding Broker

Broker has intelligence to send addresses to

the right service

If it gets a hit it stops
If it doesn’t match to Address Point, request is

logged for follow up

By using the SAM Address Points and streets

every day, they are improved for Emergency Response
