Standards and Guidelines

"Information will be the fuel for the future economy. Access to information, and effective use of it, will also be the lifeblood for the planning process we believe is essential at all levels to achieve Vermont's goals."
Pathways to Prosperity, Governor's Economic Commission, December, 1989.

Geographic Information Systems are powerful computer systems that can provide a sophisticated analysis and display of information highly useful to planners, analysts, and managers in government and business. This set of data standards and guidelines is designed to provide a single source of information concerning VT GIS policies, standards, guidelines and procedures so that all users can carry out their GIS activities as described by Vermont statutes (3 VSA 20(b)) - "compatible with, useful to, and shared with" the GIS activities of others.

Federal Standards

Geographic Names: The VT Board of Libraries is responsible for determining and changing the official names of features and locations in VT. More information about the board and its naming policies can be found here: http://libraries.vermont.gov/about_us/board
