Please check out the many opportunities for education and awareness-raising coming up over the next month. There are multiple locations and dates for Statewide Parcel Mapping Project Informational Meetings as well as Census Local Address Updating Workshops. You could consider an ArcGIS Desktop or ArcGIS Online training, or learn more about how Act 171 affects Land Use Planning in Vermont. Click on titles below for details.

VCGI is pleased to announce the rollout of additional lidar (tiled) data for the 2013, 2014 & 2015 Quality Level 2 collections to the VT Geodata Portal ( This release includes the “secondary” derivatives of ASPECT, HILLSHD & SLOPE. Missing from this lineup, and on hold for the moment, are the DSM and NDSM derivatives being subjected to additional quality checks before release (expected later this fall).

With the release of this data to the portal it is now available from all three avenues at VCGI: the All Lidar data product, download from the VT Geodata Portal and as image services.

For a quick map depicting lidar collection areas by year please see

• We are all eagerly awaiting the release of the 2016 Middle Connecticut River lidar collection currently under review at USGS. Though still under review, the latest feedback from USGS is that the review is proceeding as planned at the moment. Bear in mind this could change at any moment but presuming the best we will be rolling this data out in the late fall/early winter timeline. For now stay positive and we will keep you posted.

• 2017 Western VT lidar collection: The fifth and final consecutive year of lidar data collection under the multi-federal agency 3DEP (3D elevation for the nation) program, managed by the USGS, will commence Oct. 1 through “snow obscuration” with the backup acquisition windows in Spring 2018. Traditionally, the priority has been for fall flying to best capture the shorelines of major waterbodies, especially Lake Champlain, when lake levels are at their traditional lowest levels. With the completion of this acquisition Vermont will become only the third state in the nation to have statewide QL2 lidar data behind Delaware and Connecticut!

Summary of HackVT 2017 provided by Nick Floersch of Stone Environmental, Inc:

VCGI graciously provided a person (Kendall Fortney) and data to HackVT in order to inspire Vermont’s brightest hackers to build a cool GIS-enabled app that helps users discover the undiscovered Vermont. Whatever that meant to the hacker.

Most of the hackers had minimal to 0 GIS experience before the hackathon was announced in mid-September. So the BTV tech community rallied together and spent the month before the hackathon offering various trainings and events to get the potential hackers potentially aware of the potential of GIS applications.

  • Who won?
  • What cool GIS apps were hacked together with VCGI’s data?
  • How many pizzas were consumed over the course of the 24-hour straight code-fest?
  • What odd thing could be found in Green Mountain Power’s office-kitchen freezer?

These questions can be answered (mostly) by going to the website, ya goofball! So get over there and find out.

And next year when HackVT rolls around, remember… you can win this event, too.

VCGI is pleased to release the latest batch of orthoimagery cache.  These “best of VT imagery” services include the latest 2016 NAIP (leaf-on 60cm) and 2016 VT orthoimagery (leaf-off 30cm + 15cm).  Caches are available in Web Mercator as well as VT State Plane Meters (NAD83).

Don’t worry, if you currently use these services in your desktop GIS and and/or apps nothing has changed (beyond the data in).  No need to rewire anything.

All of these services can be consumed via Esri clients/APIs AND/or open source clients/APIs.
