VT Data - Hydro-Flattened/Hydro-Enforced Breaklines from QL2 Lidar
This metadata applies to hydrologic break lines derived from Quality Level 2 (QL2) Lidar 'collections' with a resolution (RESCLASS) of 0.7m. For an overview of the VCGI Lidar Program please see 'VCGI.VERMONT.GOV/LIDAR'. For specific details on each project extent's 'point cloud', e.g., flight dates, nominal pulse spacing and RMSEz etc., see the VCGI LiDAR data product page for links to each extents vendor based metadata - http://vcgi.vermont.gov/warehouse/products/ALL-LDR_MIX_LIDAR_STATE_ALL. NOTE - QL2 hydrologic breaklines were produced from 5 individual collections possessing slightly different datums: 2017 Western VT - NAD 83 (2011); 2016 Mid-CT River VT - NAD 83 (2011); 2015 Windham_VT - NAD 83 (NSRS 2007); 2014 'Eastern' VT - NAD 83 (2011); 2013 Rutland_VT_Lidar_Data - NAD 83. Refer to vendor based metadata for detailed coordinate reference information. For the range of ground collection dates, by collection, see the various "Source Citation" sections below.
