VT Data - Hydro-Flattened/Hydro-Enforced Breaklines from QL2 Lidar
收藏资源简介:
(Link to Metadata) 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 https://vcgi.vermont.gov/data-and-programs/lidar-program. 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.
