VT Building Footprints Geospatial Data Standard
This standard applies to Vermont’s master building footprints geospatial dataset as managed by the defined Data Steward.
Objectives
• Define a data standard that supports use of data which models building footprints in multiple contexts; contexts include emergency management, planning, and analysis. NOTE: This standard and the associated statewide building footprints dataset is NOT intended for uses such as property assessment and site engineering.
• Define a data standard that supports a workflow which merges best-available building-footprint data from multiple sources into a single dataset stewarded by VT Enhanced 911 Board; sources include local governments, RPCs (regional planning commissions), lidar, aerial imagery, and the public domain.
• Define a data standard that supports availability of high-quality building footprint data–in terms of shape integrity and attribute integrity.

Vermont Utility Pole GIS Data Standard
The purpose of the VT GIS Pole Data Standard is to foster a uniform system for pole information. It is designed for all utilities and telecom organizations to effectively plan and manage their infrastructure over time. The Standard identifies the type and form of information about utility poles that are most useful. This can be used to guide decisions about what information to collect and maintain on these assets.
***Applicability***
This Standard is for use by all of Vermont’s pole-owning utilities and telecom organizations and their consultants or contractors.
***Maintenance***
The Vermont Department of Public Service is the steward for the Standard. Individual pole owners are responsible for the datasets related to poles they own.
***Adoption***
Nothing in this Standard requires its adoption, either in whole or in part, by any entity, including pole owners or other users.

EGC Geospatial Data Exchange Protocol
The EGC Geospatial Data Exchange Protocol is a framework of data-exchange specifications that yield efficient and effective sharing and exchange of geospatial data resources between EGC-member organizations. The protocol brings clarity, consistency, and reliability to data exchange processes. It is based on adopted standards and best data-management practices.
Procedure: Adoption of VTGIS Standards and Guidelines
This document establishes a clearly defined procedure for the adoptionof VT GIS standards and guidelines.
VT Open Geodata Portal: ArcGIS Server Web Services Configuration Guidelines
This guideline outlines best practices for creating ArcGIS Server web services and registering them with AGO for the purpose of supporting the federating VT Open Geodata Portal.
ArcSDE Configuration and Management Guidelines
This guideline is designed to help agencies in the State of Vermont who plan
to configure and manage an ArcSDE1 installation. It includes a set of guidelines that
will help ensure greater compatibility between Agencies in the State of Vermont. The
hope is that this will lead to improved data sharing and exchange, and create the
foundation for an Enterprise VGIS System.

Vermont GPS Guidelines
This section can be used as a stand-alone reference to aid users of Global Positioning Technology (GPS) in gaining a better
understanding of the technology and to improve the quality and accuracy of the data they acquire. It also provides the
foundation for Section B - Data Accuracy Standards and Section C - Content Specifications that are geared to support
project where GPS data is acquired through contractual agreements.

Horizontal Datum Conversions
This paper outlines the steps required to convert ARC/INFO coverages
from the North American Datum of 1927 (NAD27) to the more
accurate North American Datum of 1983 (NAD83).

Managing Data Layer Updates
Data maintenance is often an expensive yet neglected aspect of
managing GIS data. Each data layer is unique and will have its own
system for making and tracking updates. By consequence, tools for
data maintenance are generally not built into GIS software.
This guideline contains a collection of techniques and procedures for
managing GIS data layer updates. Appropriate techniques can be
adopted (with modification as need be) for a given data layer. Some
data layers change very little over time, and may only require simple
procedures for reporting errors and making rare revisions. Other layers
change often and require procedures for recording updates in a manner
that supports quality control and tracking of changes over time. A full
range of techniques is discussed here, including methods which enable
an audit trail of modifications over time for a given feature. The text is
primarily intended for those familiar with the Arc/Info GIS software.
