The Bureau of Technology Services, Data Operations Section consists of the Database Unit, Mapping Unit, and Community Relations Unit. The Data Operations Section interacts with numerous towns each month to assist with the mapping and addressing process. Utilizing global positioning systems our personnel collect and verify address and location data for use in creating maps. Our cartographers create and maintain detailed maps which assist towns in developing addressing schemes conforming to National Emergency Number Association (NENA) standards. This information is primarily used to accurately display addressing information when a call comes in to 911.

New Hampshire 911 Data Status Map

The New Hampshire 911 Data Status Map displays the progress of the Data Operations Section's work on updating the entire state to our current Enhanced NH 911 Standard. Municipalities collected prior to the Enhanced standard are considered Legacy standard. Mapping data for Legacy Standard municipalities does not contain Multi-unit residence and business data, driveway collections, or structure-specific placement of address points. Municipal mapping status are broken into four categories:

Status Definitions

1. Verification Required – Data Operations has not collected structures, driveways, etc.
2. Legacy Mapping Standard – Municipal-verified address points exist but the data set does not include Multi- unit structures, driveways, and/or address points placed on the structure.
3. NH 911 Standard – Data Operations has updated the municipality's multi-units (residence and business) and other items from the Legacy Standard. This is our current standard within Data Operations
4. In-Development – Data Operations is currently working on collecting, reviewing, and updating the municipality to NH 911 Standards.

New Hampshire 911 Maintenance Map

The New Hampshire 911 Maintenance Map displays the process of updating the mapping data to reflect new construction. Each municipality is responsible for notifying Data Operations when a new street or addressable structure is approved, built, or demolished. Each dot on this map represents a new street or new addressable structure that was added to the mapping dataset. Additionally, each municipality is shaded to show the level of maintenance requests submitted to Data Operations.
