Resources

GIS attributes contain information associated with geographic features
on a map. GIS users, present and future, will most likely need to
develop attribute tables for new layers of map information. Existing
attribute tables will need to be expanded as well. The Vermont Center
for Geographic Information, Inc. (VCGI) encourages Vermont users of
geographic information to use the same base attributes and codes so
that data can be more easily exchanged and understood by all users.

The Vermont Future Land Use GIS Data Standard seeks to: 1. define a data framework for using GIS to map regional future land use plans.
2. Define a data framework that supports easy identification of: a) RPC to which a data set pertains.
b) adoption date of plan that the data set models.
3. Provide the data framework as a resource that can be extended to meet local-regional business needs.

The objective is to provide a source document for any organization or
political body wishing to regulate the use of the Vermont Coordinate
System, and as such, the impact of these standards is dependent on the
actions of those outside institutions. The reasons for utilizing the
Vermont (state plane) Coordinate System are:
1. To describe on a common datum, the position of points on,
above, or under the surface of the earth.
2. To perpetuate said positions in a convenient format.
3. To standardize the location of objects, points, and other
entities, as recorded in geographic/ land information systems,
(G/LIS) and other spatially related databases, for use in analytic
and mapping applications.
4. To facilitate future survey retracement of land boundaries.

This guideline will identify aspects of the parcel mapping process, issues to consider, and provide template documents that will assist listers, assessors, and other town officials with their duties as they relate to the development of parcel maps and data. An overview of the process is provided before the template documents. Please refer to the current VT GIS Parcel Data Standard at the VCGI web site (vcgi.vermont.gov) for technical specifications relevant to the creation or update of the parcel data used to create maps.

This standard provides a common data-schema for exchanging and conflating generalized 3-phase-power GIS data; the intended result of using this standard is production of data sets that are used for cursory analysis and broad-stroke planning (e.g., energy planning). The data schema’s simplicity supports simple data-load processes and efficient exchange/conflation of data amid heterogeneous sources. Ideally, this standard yields a statewide 3-phase-power GIS data set that is updated at least annually.

The VT Zoning GIS Data Standard seeks to:
1. Define a data framework for using GIS to digitally map municipal zoning district information.
2. Provide a solution that can be used to keep a geographical representation of zoning districts up to date as amendments occur.
3. Provide a time-aware solution that can be used to retrieve historical zoning information.
4. Provide a data framework that supports data integrity, spatial reliability, and appropriate data use.
5. Provide the data framework as a resource that can be extended to meet local municipal business needs.

The Vermont Protected Lands Geospatial Data Standard seeks to: 1. Define attributes and acceptable attribute values for a geospatial database identifying protected land in Vermont.
2. Define data format and structure for the Protected Lands Database
3. Define Metadata requirements for the Protected Lands Database
4. Provide procedures for submitting new or updated Protected Lands Geospatial Data to VCGI, so that the data can be included in the next update to the Protected Lands Database.
5. Define the intended time frame for updates to the Protected Lands Database

The purpose of this Tagging Standard is to establish a tagging framework that yields consistently positive user and publisher experiences with Vermont’s Open Geodata Portal in terms of data searching, data discovery, portal organization, and portal-content presentation.

This document defines standards for registering your data, web services, apps, products, and tools within AGO so that they can be discovered via the Vermont Open Geodata Portal (Portal). The purpose of these standards is to support consistent implementation and maintenance of a federated Portal that will connect publishers and consumers in a user-driven portal that facilitates finding, exploring, and consuming geospatial information.
