Streets & Addresses

NYS Address Points are available statewide or create custom filters to download specific areas. For instructions on how to create a custom filter, see this document:

A map service of the Street and Address Maintenance (SAM) Program Address Point file is available here. The SAM Address Point web services are projected in Web Mercator (Auxiliary Sphere).

The map service named SAM_Address_Points_Symbolized has different symbology for each of the 5 PointType values (see image). 

The map service named SAM_Address_Points has all points symbolized the same way.

If the purpose of downloading the address points is for geocoding, NYS ITS has a publicly available geocoding service which includes the address points along with other layers.

Program Objective:

The Street and Address Maintenance (SAM) Program maintains statewide authoritative street and address point databases to support Next Generation 9-1-1 (NG 9-1-1) and other stakeholders through extensive state and local government partnerships, and the use of data maintenance tools. Data products are compliant with National Emergency Number Association (NENA) Standards, are publicly available, and are the source of the NYS enterprise geocoding service.

Background:

From 2012 through 2015 the NYS ITS Geospatial Services, formerly known as GIS Program Office, built out a detailed statewide address point database by improving the positional accuracy of the existing NYS Address Points, adding sub addresses (e.g., apartment, building, suite, floor, etc.), and moving them into the NENA address standard. Concurrently, the NYS Streets database was also migrated to the NENA standard. Standardized, accurate, and up-to-date street centerlines and address points are needed in NG9-1-1 systems.

Building and maintaining street and address point data at the high level needed for 9-1-1 dispatch ensures it is suitable for multiple applications. For example, the SAM databases are also being used to host a statewide geocoding service. State and local agencies need to geocode addresses as point locations to support a variety of functions. This allows multiple state agencies, local governments and other entities to utilize this shared service to get consistent, accurate geocoding results. In addition, this eliminates the redundant cost and effort of each organization maintaining its own geocoding service, and the potential of different entities receiving conflicting results from different geocoding services.

Maintenance: 

NYS Address Points and NYS Streets are updated in partnership with State, county and local governments. Some data maintenance partners use our free web-based data editing application, GeoComm Contributor, to update the NYS Address Points and the NYS Streets. While other counties chose to edit data locally and provide updates on a scheduled basis to the SAM Program. The SAM team incorporates those updates within the NYS Address Points and NYS Streets data for all State, county and local governments, and performs daily QA/QC on all Street and Address Point edits. Even if counties are not using Contributor for data maintenance, a GIS Data Hub account can be provided to allow access to the updated data and allow for data sharing between State, county and local governments.

The National Emergency Number Association (NENA) promotes the implementation and awareness of 9-1-1, as well as international three-digit emergency communications systems. NENA works with 9-1-1 professionals nationwide, public policy leaders, emergency services and telecommunications industry partners, like-minded public safety associations, and other stakeholder groups to develop and carry out critical programs and initiatives, to facilitate the creation of an IP-based Next Generation 9-1-1 system, and to establish industry leading standards, training, and certifications.

NYS Streets and Addresses are maintained in the NENA Standard for NG9-1-1 GIS Data Model, which supports the NENA Next Generation 9-1-1 (NG9-1-1) Core Services (NGCS) of location validation and routing. This model also defines several GIS data layers (layers) used in local Public Safety Answering Point (PSAP) and response agency mapping applications for handling and responding to 9-1-1 calls. 

The SAM Program is working diligently with our partners to maintain accurate and high quality statewide street and address point databases for 9-1-1 and other purposes. Due to the complexity and size of the NYS Address Points, we find participation in developing NENA standards is crucial.   We actively participate on GIS Standards development workgroups to ensure the data standards are written with NYS and data set generation in mind.
