The Vermont LiDAR Initiative (VTLI) was created in 2012 by the Vermont Center for Geographic Information (VCGI) as a strategic response to Hurricane Irene with the goals of supporting the coordination, acquisition and dissemination of statewide LiDAR. The initiative is supported by the “LiDAR Workgroup” currently comprised of federal, state and local partners : U.S. Geological Survey, National Resource Conservation Service, UVM Spatial Analysis Lab, VT Assoc. of Planning & Dev. Agencies, VCGI, VT Agencies of Agriculture, Natural Resources & Transportation, Lake Champlain Basin Program, U.S. Forest Service, VT Sustainable Jobs Fund and the VT Geological Survey.

Lidar data for the United States portion of the Missisquoi Watershed in Northern Vermont. Data were collected during leaf-off conditions in 2008 and in 2009 while no snow was on the ground and rivers were at or below normal levels. The Lidar data were acquired at a nominal post spacing of 1.4 meters. Points were classified as ground (LAS class 2) using a combination of automated and manual techniques. The data were acquired by Photoscience and subsequently reviewed by the USGS and The University of Vermont. The data are made available on OpenTopography through a grant from AmericaView.
