Geographic Information Systems

A Geographic Information System (GIS) is a computer system that is used to create, manage, and analyze geographic data so that it can be used to answer questions or solve problems by being displayed on maps or used in applications.

GIS Layers

GIS works by combining data with a location so that it can be analyzed from a geographic perspective. This data can then be laid on top of other types of data or imagery to reveal patterns or relationships within it. This provides all Town staff with a powerful tool to inform better decision making.

Responsibilities

The GIS Office, housed in the Town's Information Technology Department, is responsible for:

  • Managing tools to develop, maintain, display, and analyze digital map layers
  • Implementing policies and procedures to ensure geographic data quality
  • Building applications that link base map layers to other spatially referenced data
  • Producing maps and applications for all Town Departments, Boards, and Committees
  • Providing GIS training and support to all Town employees
