Geographic Information Systems (GIS) Department

What is GIS?


A Geographic Information System (GIS) is a software-based information management tool that Westford uses to help organize, maintain, and analyze geographic-based information. GIS gives the Town ability to link geographic information to Town databases and use the data to make departments more efficient so that they can provide better customer service. This "on-demand" access to geographically linked data improves decision making capabilities at all levels of government.

GIS in Westford


Westford has been using GIS since 1999 and maintaining various datasets including parcels, buildings, roads, zoning, conservation areas, utility systems, and more. GIS applications are installed in workstations in many departments in Town, such as Engineering, Water, Planning, Recreation, Town Clerk and Fire Department. There is also a mobile version of GIS used in Town vehicles. This mobile version displays landbase information overlayed with utility information and utilizes GPS navigation.

In the spring of 2005, the Town contracted a flyover to take aerial photographs which provided high resolution orthophotos and a full set of landbase feature layers (also called planimetrics).

In the Winter of 2008 the town partnered with other towns in the region through NMCOG to purchase a regional aerial photograph which included oblique imagery such as what is seed in the "Birds-Eye" view in BingMaps.
