Finding and Using Vermont Lidar Data: An Introduction (2022)

Interested in finding and using freely available Vermont lidar-derived elevation data products, perhaps for the first time? This webinar hosted by the Vermont Center for Geographic Information (VCGI) covers how to find and understand lidar-derived data, with emphasis on web browser-based tools to view them. We will cover data products made available by VCGI’s lidar program, and the VT Interactive Map Viewer as a means of access. Video recording is available here:

Topographically-defined Floodplains: Relative inundation for conservation and restoration planning in the Lake Champlain Basin, Vermont

The Topographically-defined Floodplains were generated from high-resolution topographic data along rivers draining greater than 2 square miles in the Vermont portion of the Lake Champlain Basin. These floodplains are intended for planning and research use by government, academic, commercial and non-governmental agencies; they are not a substitute for FEMA Flood Insurance Rate Maps and are not intended for regulatory use. A greater geospatial coverage of floodplains in the basin will support analyses of floodplain and wetland processes and restoration and conservation planning for improved water quality, enhanced flood and climate resilience, and expanded habitat and ecosystem functions. Lateral extents of flooding for storms of recurrence intervals ranging from 2 to 500 years are represented in the dataset.

VT Building Footprints Geospatial Data Standard

This standard applies to Vermont’s master building footprints geospatial dataset as managed by the defined Data Steward.

• 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.

This Standard is for use by all of Vermont’s pole-owning utilities and telecom organizations and their consultants or contractors.

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.

Nothing in this Standard requires its adoption, either in whole or in part, by any entity, including pole owners or other users.
