As stipulated by the legislature, MassGIS’ responsibilities include coordinating geographic information system (GIS) development efforts at all levels of government in the Commonwealth. GIS technology can provide cities and towns with significant benefits: greater information transparency and access by citizens; more effective asset management; improved service delivery; the ability to visualize current status and to plan for future projects.
Are you the Addressing Authority in your municipality?
To help maintain the 911 Address database, cities and towns are required to notify MassGIS when new addresses are adopted. Most municipalities have an internal reporting system for all departments and we need to be notified too.
MassGIS's work on addressing with the State 911 Department
MassGIS is maintaining a complete Statewide address point database for State 911. The links below explain 911 grants, how to get address data files, and other mapping layers we've created to support 911. The mapping layers can be used for many purposes.
As the Commonwealth’s Bureau of Geographic Information, another of MassGIS’s responsibilities is working with stakeholders on establishing standards for the acquisition, management, and reporting of geographical information.
