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 helps us manage and maintain the towns infrastructure. 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.
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).
