The VT Center for Geographic Information (VCGI) is pleased to release a BETA version of Vermont’s new Open Geodata Portal!
VCGI and its partners have built a website that connects publishers and consumers and helps them find, explore, contribute, and use geospatial information and resources. The VT Open Geodata Portal (Beta) “federates” geodata, web services, and geospatial applications from many sources (publishers) including several State agencies (e.g. VT Agency of Natural Resources, VT Agency of Transportation, and VT Agency of Human Services). VCGI would like to thank our partners for their dedication to improving access to Vermont’s geospatial assets.
What do you think? Please take a few minutes to explore the BETA site (http://geodata.vermont.gov), kick the tires, and let us know what you think (http://geodata.vermont.gov/beta_survey). Your input will help us improve the website. We plan to release a final version by the end of the year. Thanks!
P.S. Known “bugs/limitations” have been documented here (http://geodata.vermont.gov/beta1_bugs).

Exciting news from Pat Moulton, Secretary of ACCD:
Lucy Leriche and I are excited to announce that John Adams has been selected as the new Director of the Vermont Center for Geographic Information! Most recently, John served as Planning and Policy Manager at the Department of Housing and Community Development within the Agency of Commerce and Community Development.
John brings to VCGI experience and enthusiasm for using data and mapping to guide decision making processes across state government. Since beginning at DCHD in 2012, John has been a leader in land use policy, legislative initiatives and managing special projects – notably using GIS to improve workflows and to ensure Vermont’s public investments are supported by data. He is the primary author of Vermont’s new Planning Manual and has been a key figure in a wide variety of interagency initiatives relating to land use, housing, transportation and energy. As someone with track record of building consensus and commitment to improving customer service in state government, he was the recipient of a 2016 Public Service Recognition Award.
John is a certified professional planner who has worked at the municipal level and has taught Land Use Policy and Economics at the University of Vermont. He holds a Masters of Urban and Regional Planning from Queen’s University and a Bachelor of Arts in Environment and Development from McGill University. In his personal capacity, John volunteers on the Montpelier Planning Commission, roasts coffee and brews beer.
A search committee involving multiple agencies and partners selected John from a pool of incredibly well qualified candidates from around the country. John will start with VCGI on Tuesday, September 9th, 2016.
Please join us in congratulating John on this exciting new position!

The 2016 Vermont Remote Sensing Workshop will provide hands-on training with a broad range of remote sensing technologies, including Unmanned Aircraft Systems (UAS), lidar, and thermal satellite imagery. The workshop is designed to help federal, state, regional planning commission, and local GIS users improve their ability to harness the power of remotely sensed data. Funding for this workshop is provided by AmericaView and the US Department of Transportation.
Dates and Locations
- August 9, 2016: 9AM-11AM, UAS flight operations in Waterbury, Vermont. This is an optional session and is dependent upon the weather.
- August 10, 2016: 9AM-5PM, University of Vermont, Aiken Center (81 Carrigan Drive), Room 101. Lunch will be provided!
Register here for only $10: https://secure.vermont.gov/ACCD/eventreg/event.php?eid=75
There are 18 seats available for the August 10th training. Priority will be given to government (federal, state, regional planning commission, and municipal) employees. Participants should be very comfortable working with geospatial data and have experience with desktop GIS software.

New LiDAR Data Available:
1. 2013 Rutland/Grand Isle data “collection” which includes the Mad River Valley (see map here): 0.7m resolution, Quality Level 2 (QL2). – DEM has been posted, Hillshade and Contours are coming soon.
2. A pre-release portion of the 0.7m Quality Level 2 (QL2) 2014 “Eastern VT” data “collection” which includes a portion of Georgia and stretches south along the lake into Charlotte in Chittenden County (see map here). – DEM and Hillshade have been posted, Contours are coming soon.
Visit VCGI’s Open Data page and search via keyword “lidar” to see the list of new and updated data: http://vcgi.vermont.gov/opendata
Changes to Existing Data:
NOTE: some of the data identified below did NOT make it through the posting process. We are working through some technical issues and hope to resolve them in the next couple of weeks.
1. Updated naming convention to all LiDAR related data. E.g., “Elevation_DEM1m1020_2005.img” is now “Elevation_DEM1M2005_1020.img”.
a. Digital Elevation Model (DEM) data now reflects its “hydro treatment”, e.g., DEM = “pure” DEM; DEMHF = “Hydro-flattened” DEM; DEMHE = “Hydro-enforced” DEM; see USGS’s “Hydro Treatments of LiDAR Derived DEMs” powerpoint for details.
2. All downloadable data layers are in their original, vendor-delivered tiling structure, re-projected to VT State Plane Coordinate System NAD83 meters, Zunits meters and the Erdas Imagine format. This primarily affected the following collections:
a. 2008 “Lower” Missisquoi – Reimported to original 1.6m, “hydro-flattened” DEM format;
b. 2010 “Upper” Missisquoi (a.k.a. “Rock River”) – Reimported to original 1.6m, “hydro-flattened” DEM format;
c. 2012 Bennington County – Reimported to original 2m, “pure” DEM format;
3. Only DEMs and contours (DEM/DEMHE/DEMHF) are provided in tiled format. Other derivatives are in single mosaic file format only.
a. When contour data was part of the original vendor delivery they are in the same tile index structure as the DEMs.
b. When contour data was not part of the original vendor delivery and created by VCGI in 2013/2014 they are in the “Ortho9” tile index.
4. All primary (DEMs) and secondary derivatives (ASPECT, DSM, HILSHD, nDSM & SLOPE) are available in a single, mosaic file format covering the full “collection” extent.
Changes to Metadata:
- All LiDAR metadata files have been updated to latest EGC format (May 2016).
- For original vendor metadata see “All VT LiDAR on an External drive” main page for all project level metadata in a central location (these are original vendor metadata for LAS data).

In crisis situations like an earthquake, volcanic eruption, avalanche or epidemic, first responders need up-to-date digital maps to navigate the affected area. However, many remote regions around the world simply do not have the data necessary for aid groups to safely traverse city streets and locate rural villages post-disaster. In the event of a disaster, the Humanitarian OpenStreetMap Team (HOT) mobilizes volunteer mappers around the world to focus their efforts on data deficient regions.
UVM’s HOT holds mapathons once or twice a month at a computer lab in the Aiken Center on the UVM campus in Burlington. Read about recent mapathons here: http://letters-sal.blogspot.com/2016/06/uvm-humanitarian-openstreetmap-team.html and contact mapathon coordinator Noah Ahles to be added to the notification list: firstname.lastname@example.org Cell: 914-960-4613
Your company or organization can help support these effective volunteer events:
- Help pay for refreshments for the volunteers!
- Send volunteers!
- Contribute directly to the International Humanitarian OpenStreetMap Team in honor of the UVM Team (let us know so we can thank you and give you credit!) – https://hotosm.org/donate
- We will acknowledge your contributions at our events and at our event registration web pages.
- Contact Noah (above) if you would like to contribute.
