SAM

The Office of Cyber Security (OCS) has embarked on a major project to create a detailed statewide address point dataset. This will expand on the current NYS Address Points, improve their positional accuracy and maintain them in the NENA address standard. Standardized, accurate, and up-to-date address points are a required dataset for Next Generation 911 (NG911). This presents a challenge because consistently formatted address data are not uniformly available across the state. Centralizing the address point data build effort will result in the least costly solution for all.

Building the data for the high level needed for 911 dispatch will also ensure it is suitable for multiple applications. For example, the SAM dataset will also be 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 will allow multiple state agencies, local governments and other entities to utilize this shared service to get consistent, accurate geocoding results. In addition, this will eliminate 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.

The SAM dataset will accommodate sub-addresses (e.g. apartment, building, suite, floor, etc.) as determined necessary by 9-1-1 officials. The SAM initiative nicely complements the NYS Streets & Address Points Data Maintenance which has been underway at OCS for several years (see the Streets & Address Maintenance tab above).

NYS Streets & Address Points Data Maintenance

OCS continues to maintain the NYS Streets and NYS Address Points data sets, containing over 135,000 miles of streets and more than 4 million address points. Over time, the NYS Address Points dataset will be phased out and replaced with the Address Points developed as part of the SAM Project. The NYS Streets data set contains numerous attributes including primary street name, alternate/alias street names, address ranges, route numbers, classification, jurisdiction, and other attributes needed for geocoding or routing applications.

The data sets are available to NYS GIS Data Sharing Cooperative Members and NYS local governments at no cost through the NYS GIS Clearinghouse (http://gis.ny.gov/gisdata/inventories/member.cfm?OrganizationID=522). Data is released quarterly in March, June, September and December. A version of the NYS Streets data (http://gis.ny.gov/gisdata/inventories/details.cfm?DSID=932) containing all but the address and routing attributes is also freely available to the public.

The NYS Streets and NYS Address Points datasets are used extensively by State agencies, counties, local governments, federal agencies, and increasingly by the emergency response community. To keep the data up-to-date, the Office of Cyber Security coordinates with local government partners to identify needed street and address changes such as the addition of new streets or address points, correction of street names, addition of alternate/alias street names, and refinement of address ranges. Edits are reported using MMNT (Map Maintenance, Notification and Tracking), a secure web application that allows authorized users to submit updates and corrections. Edits are made once and the updated data sets are shared back with all governmental agencies, minimizing duplication of data maintenance efforts.

County and local governments interested in learning more about a potential partnership opportunity to share street and address changes should contact the NYS Office of Cyber Security at 518-242-5200.
