Maps of land use and land cover are fundamental tools for natural
resource management and planning. These land use/cover codes
provide a standard system by which units of land can be categorized.
Land use/cover maps serve to: assess the area and distribution of individual land use/cover
categories (such as cropland and pasture, code 21), show the diversity of the landscape, contrast the land diversity of different regions, monitor changes in land use and/or cover over time.

The VGIS Land Use/Land Cover Codes have been developed to provide compatibility with existing USGS codes, provide codes tailored to Vermont's landscape, permit land coding at a various resolutions (local, regional and
state), avoid and clarify redundant classifications which depend on interpretation.

Standards for a map coordinate system are critical to retaining the
integrity of Vermont Geographic Information System (VGIS) spatial
data. Therefore geographic data stored in other coordinate systems
require conversion for use in VGIS.

The purpose of this document is to provide guidelines covering the
digital conversion of existing manually drawn data into GIS format.
The goal is to obtain the best possible digital map representing an
original analog map. As such, it is assumed that a suitable source map
exists. While the ultimate quality of the database is dependent on the
quality of the source materials and the care used in automation, the
procedures for original mapping are not discussed. It must be
remembered that precise automation procedures will not improve an
inferior base map.

This Life Cycle Support Policy is designed to help communicate to VCGI's users the technical resources available during a web application's life span and to provide advanced notification of planned changes to web applications offered by VCGI. This document addresses VCGI's policy and plans regarding web applications hosted by VCGI.

This document details the policy of the Vermont Center for Geographic
Information, Inc. (VCGI) in regard to procuring VGIS-compatible
data, services, and products for VCGI customers and for the VGIS
community from public agencies and commercial GIS service
providers. VCGI recognizes the importance and usefulness of all such
public and private sector providers to the Vermont Geographic
Information System (VGIS).

To establish policy regarding public access to the information and
electronic products available from the Vermont Center for Geographic
Information, Inc. (VCGI).

This policy describes the roles of the Vermont Center for Geographic
Information, Inc. (VCGI), local and state government, regional
planning commissions, and other organizations, as partners in the
Vermont Geographical Information System (VGIS).

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 Handbook is designed to provide a
single source of information concerning VGIS policies, standards, guidelines and
procedures.
