A Geographic Information System is a computer-based technology that is used to manipulate data from a geographic perspective. It organizes information about the earth's surface and the objects found on the earth.

The Environment Division uses this technology to manage, analyze and display geographic information about Akwesasne and surrounding areas.

The Environment Division's GIS program began in 1995. It has evolved into a vital component in the decision-making process for management, restoration and remediation of Akwesasne's natural and cultural resources. The program also provides GIS services to other Tribal programs and projects, community members, local businesses and non-profit entities throughout the Akwesasne area.
