VCGI is pleased to announce the initial rollout of lidar image services covering all or parts of Addison, Bennington, Chittenden, Franklin, Grand Isle, Lamoille, Orleans, Rutland, Washington, Rutland and parts of Caledonia and Orange Counties (see map below). The remaining area should have services by the end of 2017. The links below will take you directly to the Rest Endpoint Page for each service.


  • The DEM image service was intentionally published with the default gray scale color ramp to support flexibility for the user. For details on how you can generate derivatives on the fly using this service, please watch the March 2017 webinar on how to use the new lidar imagery services (the powerpoint used is also linked from the event archive).
  • The Hillshade services are being initially release without first being “cached” in order to make them available as early as possible while the time intensive cache generation process is conducted.
  • All of the DEM data in these services are also available for download: Keyword search at geodata portal on 0.7 meter will bring these and other high resolution elevation products to the top of the search results list.
  • Associated contour data (both 1’ and 2’) are also available: Keyword search on 1 ft contour and 2 ft contour work well.

PHASE I RELEASE: As part of our ongoing release of 2016 orthoimagery data and web services, the VT Center for Geographic Information (VCGI) is pleased to announce our “Phase I” release 2016 web services.  This release includes the following New and Updated web services.

New 2016 Imagery Services
  • Vintage-4 Imagery Services* – The term “Vintage-4” refers to the 4th generation of digital VT orthoimagery, which is imagery that is being collected during a 5-year window (2016 to 2020).  These services (Color, Color Infrared, Black & White) are currently limited to 2016 orthos, however, 2017 to 2020 imagery will be added once collected and processed.  You can get to them here
Updated All Imagery Service

* These are dynamic services (not cached) and therefore will render more slowly than cached services. 

How about cached services?

These services require lots of backend processing before they are ready, therefore they will be released in the following phases

  • PHASE II ~ April 2017: The “Phase II” release will include cached versions of the color 2016 imagery (VT State Plane and Web Mercator). 
  • PHASE III ~ May 2017: The “Phase III” release will integrate the 2016 imagery into Vermont’s fully cached “Best of” imagery services including 1) Best of Color, 2) Best of Color Infrared, and 3) Best of Black and White (panchromatic).  It is anticipated that this release will also include the 2016 60cm NAIP imagery.

The VT Center for Geographic Information (VCGI) is pleased to announce the release of new Vermont Orthoimagery collected in 2016.  This release represents the 1st acquisition year of a new collection effort (2016-2020 map here) which will result in a completely new set of 30cm leaf-off 4-band orthoimagery.  Additionally, we are collecting 15cm imagery for specific “buy-up areas”.

The 2016 orthos cover approximately 1/5 of the state, a swath cutting across Rutland and Windsor counties.  30cm imagery is available for this entire area; 15cm is available for the buy-up areas (shown with hatched lines on the map).


  • Higher Resolution Base Imagery – The base orthoimagery is being collected at 30cm Ground Sample Distance (GSD).  This nearly halves the resolution from previous ortho vintages (50cm).
  • 6-inch Resolution for Buy-up Areas – Approximately 10% of the state is being collected at 15cm GSD.
