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: email@example.com 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.

State-Wide FEMA DFIRM Data Posted
A state-wide FEMA DFIRM data set (where DFIRM is available – see map) has been posted in Vermont’s Open GeoData Portal: http://vcgi.vermont.gov/opendata. This new data posting replaces the individual county-based and town-based DFIRM data sets that were previously posted to the portal. This new data set is catalogued in the portal with the database name EmergencyFlood_DFIRM; It can be found by searching with the keyword “DFIRM”.
The DFIRM data set is available through the portal as a .zip package that contains shapefiles, tables, metadata files, and a .lyr file.
VCGI appreciates VT Agency of Natural Resources (ANR) staff for keeping VCGI abreast of the status of DFIRM data and providing symbology that is incorporated into the .lyr file.
NOTE: New flood maps in Bennington County just became effective on 12/2/2015.
NOTE: See the Flood Ready Vermont web site at http://floodready.vermont.gov/ for information on flood readiness.
All VT Imagery Service Now Includes 2015!
VCGI’s full suite of imagery services have been updated with the latest 2015 VT ortho imagery (covering southern VT).
2015 Orthos have been integrated into the following services
- All “Best of” services + caches (color, color infrared, and black & white) have been updated
- All statewide “ortho only” services (color, color infrared, and black & white) have been updated
- Individual cached 2015 ortho services have been created (SP + WM)
- The “All VT Imagery and Indexes” service (version 3) has been updated to include 2015 imagery + indexes (including tie-cut lines).
NOTE: These services also take advantage of stable “layer ids” for those hackers out there, so you can count on them staying the same when you write your code.
Additional details are available here:

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). Visit the Statewide Parcel Data page to learn more ( http://vcgi.vermont.gov/parcels ) or click here to go directly to the survey: https://www.surveymonkey.com/s/VTParcelROI.

“Six UVM staff members were recognized for their extraordinary contributions and overall impact on the university on May 5 at the inaugural President’s Our Common Ground Staff Award recognition breakfast in Billings Library.
Honorees were chosen from a pool of 24 nominees for exemplifying the qualities of the University of Vermont’s Our Common Ground, the statement of aspirations and shared values of our community: respect, integrity, innovation, openness, justice and responsibility.
Honorees were presented with a hand-crafted award designed by local artist Chris Reck that UVM President Tom Sullivan said embodies the values expressed in the President’s Our Common Ground award. Anchored by a piece of red cambrian sedimentary rock known as Monkton quartzite used in many of the university’s buildings, the award features the Our Common Ground statement transposed on an intricate woodcarving map of the campus.”
Chris Reck of Direct Design contacted VCGI for ideas regarding who might actually create the 3D wood topo map featured in this trophy. Leslie Pelch of VCGI sent a message out on the VT GIS email list serve and several people got in touch with Chris to say they might be able to help. In the end, Spencer Wright of Bristol Contours (802-355-0800) was able to create the maple topo map of a portion of the UVM campus.

Request for Information posted re: VT Open GeoData Portal:
The VT Center for Geographic Information (VCGI) currently hosts Vermont’s Open GeoData Portal (herein referred to as the GeoData Portal), which allows users to access and use geospatial information and services. This Request for Information (RFI) is designed to gather information from geospatial technology providers regarding the development of a new VT Open GeoData Portal. The results of the RFI may or may not lead to the release of a Request for Proposals (RFP).
The full RFI has been posted here http://vcgi.vermont.gov/rfps
NOTE: All questions related to this RFI should be emailed to firstname.lastname@example.org by April 28, 2014: 3PM EST. All questions and associated responses will be made publicly available by May 5, 2014: 3PM EST on VCGI’s website.
All 2013 Orthoimagery has been posted:
Ortho imagery covering the northwest portion of the state as well as the Barre-Montpelier area was collected in the spring of 2013. All of the northwest corner was collected in 4-band color infrared as well as black and white with .5 meter pixels. Additionally, much of Chittenden County was collected at a resolution of .15 meter pixels, with the more mountainous eastern edge of the county being collected at .2 meter pixels. The Barre-Montplelier area was collected as a resolution of .3 meter pixels. More info here: http://vcgi.vermont.gov/2013_imagery_available
Mapping it up in VT and NH (webinar) scheduled:
VT and NH both have powerful, newly updated online map viewers. While each viewer is customized to the state’s GIS resources, they share a common framework and much of the same functionality. Come for a tour of the new interface(s), layers and tools for both viewers. Participants in this webinar will learn how to make maps from the layers provided by VCGI and NH GRANIT, add your own data to the maps, save your map as an image or to print, and more.
Date: Wednesday, April 30, 2014

VCGI has posted a Parcel Boundaries Web Map Service that will be updated at least annually as we receive updated parcel data. Web map services allow users to bring map layers and imagery into their GIS projects or map mashups without actually downloading any data by connecting to the service of choice via the internet.
Contact Leslie (email@example.com or 802-882-3002) if you need help understanding how to connect to this service. More info here: http://vcgi.vermont.gov/warehouse/web_services/map
