  • Save your map via "Save" button (NOTE: must sign-in to ArcGIS Online account first – available for free).
  • Lidar terrain / hillshade data (~50% of the state).
  • Access to VCGI Open Data via a Layer Catalog
  • Download the data layers from the Table of Contents (refer to FAQ for details).
  • Determine when aerial photos were taken (refer to FAQ for details)
  • Change how layers are symbolized so they look the way you want.
  • Export/Print maps to many different formats.
  • Get a street view (Google Street View function).

The VT Center for Geographic Information (VCGI) is pleased to announce the release of a new Vermont Open Geodata Portal (  VCGI, in close collaboration with Vermont’s Enterprise Geospatial Consortium (EGC), has built a website (Portal) that helps constituents find, explore, and access a wealth of geospatial resources. The Portal provides access to geodata, web services, and applications originating from many sources (publishers) including numerous State agencies (e.g. VT Agency of Natural Resources, VT Agency of Transportation, VT Agency of Human Services, VT E911). 

Highlights include

  • Download formats – Vector datasets are available in multiple download formats (shapefile, excel, and csv).
  • Smart search – All entries are fully indexed with tags and keywords making it easier to find what you’re looking for.
  • Data visualization – Vector datasets can be visualized using the built-in map viewer.  Users can even filter the data before they download it!
  • Big Data download tools – The Portal includes special tools for “big” datasets such as imagery and lidar.  These include the Tiled Data Download Tool and Clip & Zip Tool.
  • Modern web platform – The Portal leverages modern web technology supported by Esri (Environmental System Research Institute, Inc.), providing the State with an upgrade path for the future.

VCGI would like to thank our State Agency partners for their ongoing dedication to improving access to Vermont’s geospatial resources!

From our Database Administrator, Ivan Brown:

A lot of data was posted to Vermont’s Open GeoData Portal ( ) during late 2016 (and 2016 isn’t over!).  I want to highlight some recent data posts.

Parcels: The Vermont parcels dataset (CadastralParcels_VTPARCELS) has been updated with 6 new towns providing parcel data for the first time and 33 towns providing updated data (update 2016A).  Thank you to the Regional Planning Commissions for supporting the effort to collect parcel data and make it accessible! Additional parcel datasets are already in the queue for an update to be conducted in 2017. Visit this 2016A Update page for details!

The new Vermont Statewide Property Parcel Mapping Project and the new Vermont Statewide Property Parcel Mapping Program are gearing up.  The project and program will yield a lot of benefits to the state, including consistent parcel data structures, efficient parcel data exchange/aggregation/use, and increased parcel data coverage.  For more information on the Vermont Statewide Property Parcel Mapping Project and the Vermont Statewide Property Parcel Mapping Program, go to .

Lidar: An enormous number of lidar data derivatives were posted to Vermont’s Open GeoData Portal during 2016.  Also, more lidar data resources are always moving along the conveyor belt as lidar data coverage increases.  The lidar data derivatives can be discovered by searching Vermont’s Open GeoData Portal (  ) with the keyword “lidar” or by simply clicking on the “LIDAR related data” link.

County/Town Boundaries:  VCGI recently completed a long-awaited update to the State’s county, town, and village GIS dataset (BNDHASH).  This dataset combines (“hashes together”) data from “best available sources” to map the location of county, town, and village boundary lines.  VCGI leverages information from official surveys (when available), parcel datasets (recent), and other agency datasets (e.g. VTrans’ county/town boundary data).  This information is reviewed and weighed against existing boundary lines and supporting documentation to determine if the information should be used.  The goal is to improve the data over time.  The latest BNDHASH boundary data is available from VCGI’s Open Geodata Portal (  PLEASE NOTE:  BNDHASH feature class names have changed;  This may impact .mxd files, etc. when the new files are swapped.  The associated Vermont Geographic Area Code lookup tables “GEOCODES”, which are based on the VGIS standard, have also been updated.

Other Data Recently Posted:

  • UtilityTransmit_VECDISTLINES (VEC Primary Overhead and Underground Distribution Lines)
  • CadastralConserved_PROTECTEDLND (Vermont Protected Lands) (a new post of this dataset was conducted on 11/18/2016)
  • CadastralOther_NATWILDAREAS (Wilderness Areas, including National Wilderness Areas)

VCGI has been busy migrating the VT Interactive Map Viewer (an application that uses the Microsoft Silverlight  plugin) over to HTML5.  Today we are pleased to announce our 1st BETA! This new VT Interactive Map Viewer is designed to replace the current viewer.


  • Supported on all modern browsers (desktop computers, tablets and phones). No plugins required.
  • Complete functional equivalency to the current SilverLight viewer.
  • Access to all of VCGI's Open Data via the Layer Catalog tool.
  • Changeable layer symbology.
  • Google Street View widget to get a ground view.
  • Save your map for later use and/or sharing. NOTE: requires that you have an ArcGIS Online Account (available free

Please take the BETA for a spin:

…and when you’re done kicking-the-tires let us know what you think: SURVEY:

This is a quick one-week BETA which will be closed COB 12/12/2016.  Thanks again for your input!
