1. Description of Service
MassGIS can take various kinds of inputs, including geographic coordinates, data linked to addresses, towns or other geography as well as existing paper maps of regulated areas or resources and turn these inputs into GIS data. Many state agencies currently provide their data to MassGIS to be hosted in the Oracle repository of statewide data. From this database, located at MITC, GIS data can be served via the web either through interactive mapping (see service offering for web mapping services) or through GIS file download to a wide variety of map users including government or business entities and the general public.
Mapping an agency's mission-critical data can provide valuable insights about how best to deliver services - where the needs are and how to leverage resources most effectively. MassGIS can develop mapping from many kinds of input datasets. Once GIS data are developed, further analysis and integration with other data "layers" using GIS software can often make a significant contribution to policy development and strategic planning. A common first step is geocoding - assigning a geographic location to customer addresses. MassGIS has geocoded many millions of addresses, including statewide listings such as the property tax rolls from the Warren Group, RMV vehicle registrations, the 911 Emergency Service List etc. Some data, of course, are proprietary or confidential and cannot be published directly - but they can often be aggregated or analyzed in a way that eliminates concerns about privacy. Once geocoded, locations can be overlaid with Census block groups, legislative districts, regional office territories or any other geographic areas to provide summaries, analyze the data and discern patterns. Agencies can develop demographic profiles of their client base in this way to help target service delivery and ensure that appropriate resources are available where needed.
MassGIS Data Services include:
MassGIS maintains the most complete and accurate geocoding base available. Geocoding creates an estimated geographic location (x,y) for street addresses. Customer supplies list(s) of addresses with number, street and either zip code or "official" town.
- GIS Data Development:
MassGIS can take existing maps or lists linked to geography (e.g. regions made up of municipalities) and convert them to GIS data. GIS data development services involve creating GIS data from existing non-GIS sources. It can range from simple linkage of existing lists to geography (e.g. define regions by town) to map scanning and conversion into GIS format. In addition to doing work in house, MassGIS can provide review of specifications for conversion of existing data to GIS by outside consultants or for large and complex projects, project management services.
- Address standardization:
MassGIS can match addresses between different lists that have no other common field, using sophisticated address parsing. Address standardization involves parsing and standardizing address lists to meet the MassGIS standard (from Federal Geographic Data Committee http://www.fgdc.gov/standards/projects/FGDC-standards-projects/street-address). Geocoding "hit" rates can be vastly improved through address parsing and standardization (see service description below). Also, address standardization is required to link separate lists or tables which have only an address field in common. This need arises frequently when matching lists from different agencies which have no common ids.
- Geographic Analysis and Reporting:
Combines GIS data from different sources to derive added value. Geographic analysis and overlay will be customized to meet agency needs. Agencies can often achieve strategic insight by simply mapping their data (through service offerings described above). However, in many cases, geographic overlay will add value to the mapping, by combining different geographic layers. For example - how far are my customers, on average, from the locations that serve them? Many statistics and reports, including proximity, demographics, density, and geographic aggregation and so on can be derived from GIS analysis.
- Data Hosting:
MassGIS will host agency GIS datasets for download and for input to web mapping services. GIS data hosting allows agency data to be served from the MITC Data Center to GIS users both inside and outside Magnet (see web services description). Data hosting also allows data to be downloaded.
Support services include:
- A Service Account Manager to answer any questions or concerns regarding MassIT Services.
- Services offered through our Operations Office; including Change Management and customer access to incident management via email, phone (CommonHelp).
- The online COMiT service management portal .
- MassIT's Chargeback Billing System.

*Incidents, requests, or changes that are outside the scope of the defined service description or normal service hours will be direct charged to the customer.
3. Service Reporting
|QA Reports||These are generated for any geocoding, address standardization or data development service request detailing issues with the input data or with the data conversion that affected the output e.g., addresses that could not be matched because of formatting or missing geography.||Upon Request through COMiT|
|Project Reports||Geographic analysis and reporting is highly customized and depends on the scope of the project. Project reports include periodic status reports, percent completion for deliverables, summaries of staff effort and unresolved issues requiring customer input.||As determined by Project Team|
