Mapping Winooski River ice conditions in Montpelier

April 8, 2015

This is from the UVM Spatial Analyis Lab Blog, click below for the full post and other related posts!


This is a follow-up to our previous post on using high-spatial, high-temporal resolution imagery from our senseFly eBee to map changing ice conditions on Vermont Rivers. The Winooski River in Montpelier has a history of ice jams and flooding. As part of our Department of Transportation grant we have been gathering color-infrared imagery of the Winooski River to evaluate the use of such imagery to map changes in ice conditions.

Farewell to David Brotzman, Hello to National Life!

April 3, 2015


Big changes this week for VCGI: David Brotzman rides off into the sunset, and the VCGI office moves from Waterbury to the Penthouse of the National Life Building to join Agency of Commerce and Community Development staff.

VCGI staff and the VT GIS Community were sad to say farewell to VCGI’s Executive Director of 15 years, David Brotzman. David ushered VCGI through many changes, kept the organization focused and solvent, and helped manage the transition from public non-profit status back into state government as a division of the Agency of Commerce and Community Development. Left to Right In the picture above: Ivan Brown, David Brotzman, Mike Brouillette, Steve Sharp, and Leslie Pelch.


VCGI has officially moved out of our office of almost 13 years in Waterbury into our new digs in the National Life Building in Montpelier (ACCD is on the 6th floor). The picture above is the empty old office.

And here is VCGI’s new space in the Penthouse of the National Life Building in Montpelier. Ivan’s cubicle has the cheerful orange GIS and Leslie’s is just beyond. Mike and Steve are on the other side of the divider. We join the ACCD IT group, who have been incredibly patient, welcoming, and helpful to us during this transition!


Vermont’s Public Mapping Data Portal Is Transforming

February 20, 2015

Feb. 20, 2015

Leslie Pelch, Outreach Coordinator


After more than 20 years as a public nonprofit, the Vermont Center for Geographic Information (VCGI) will become a division of state government once again. Specifically, it will become a division of the Agency of Commerce and Community Development (ACCD) on March 30, 2015. Originally created as the Office of GIS (geographic information system) in the late 80’s, and then re-formulated as a nonprofit in the early 90’s, VCGI’s mission has never changed and it will continue to provide a one-stop-free-data experience for those seeking digital map layers for Vermont.

Most of VCGI’s staff will be making the transition into state government, where they will take up positions within ACCD’s Information Technology group. VCGI’s Executive Director, David Brotzman, has chosen not to make the transition; his work over the past 15 years has ensured VCGI’s continued effectiveness and sustainability and the VT GIS community wishes him well!

VCGI, as a distinct division, will continue to collect data from municipal, regional, state, and federal entities; make it available for free download; and provide information and links to other resources for those interested in taking advantage of geospatial technology. VCGI also participates in funded projects such as the Broadband Mapping project, digital mapping at the Department of Emergency Management and Homeland Security, and the Vermont Renewable Energy Atlas.

“Users of our services will not notice much of a change in the short term as we make this transition,” VCGI Outreach Coordinator Leslie Pelch said. “In the long term, there may be more opportunities to work with state entities not currently taking advantage of this technology. We will continue to serve all users of Vermont geospatial data.”

“We look forward to leading and advancing the coordination of statewide geospatial data and believe the role of geospatial information within state government, and statewide, is virtually limitless. ACCD is excited to meet this important new challenge with the addition of the VCGI staff into our exceptional team,” added ACCD Deputy Secretary Lucy Leriche.

VCGI staff will join their ACCD coworkers at the National Life Building in Montpelier in early April. Contact information will not change.

In October 2014, the Vermont Agency of Transportation (VTrans) hosted a workshop to help GIS users of Vermont data understand what bridge and culvert information is available, and which data set is appropriate for their needs.

A series of videos of the information presented at the workshop have been produced by Eric Goldman, Multimedia Specialist, and Sara Moulton, GIS Specialist of the VTrans Division of Policy, Planning and Intermodal Development. The videos can be accessed on YouTube at

Survey to Collect Input on the Value of Parcel Data in Vermont

December 9, 2014



VTrans has engaged the services of AppGeo to perform a Return on Investment Study as well as a Parcel Lifecycle Report. They are seeking input from a wide variety of people who live or work in VT in order to gather knowledge and opinions about the value of parcel data (one of the key ingredients of a tax map).

The VT LiDAR Initiative Presents: A LiDAR Based Web Service Prototype

October 18, 2014

Join us for a Free Webinar on November 5, 10:30 AM – 11:30 AM

Reserve your Webinar seat now at:

In an ongoing effort to “democratize” access to the wealth of information present in LiDAR data, the Vermont LiDAR Initiative (VTLI) sponsored by the Enterprise Geospatial Consortium (EGC) sub-committee “VTeam LiDAR”, presents the first Vermont LiDAR image service prototype of the 2012 Addison County project area. This freely accessible data “service” will ultimately expand to make all available LIDAR project data accessible in both basemap and imagery services. After a very brief introduction on “What is LiDAR?” we will overview the proposed suite of LiDAR-based Web Services to be created and hosted by VCGI and how it can be accessed by all users. Closing out the webinar, we will provide a brief update on the status of LiDAR data collection and distribution efforts across the state before having an open floor discussion on related topics. For a primer on LiDAR basics before the presentation please overview –

Parcels: the parcels web map service has been updated to reflect additional or updated parcel data (also available for download)


  • In addition to completing the Rutland County collection (orange in map above), the entire Winooski River Watershed plus some additional area will be collected in 2014 or 2015. The project will cover more than 2400 square miles (light green in map above), complete Lake Champlain Basin coverage on the Vermont side and include a new coverage for Chittenden County. Total project funding was $880,000 and a total of six cooperators contributed to the project.
  • A pilot area Web Map Service of LiDAR data will be available soon!
  • Updated ArcGIS Online VT LiDAR map makes finding information about available LiDAR and derivatives easier:

Fall Webinar Series Scheduled (all will be recorded and posted at VCGI’s Youtube channel):
