Resource Abstract:
description: (<a href="http://maps.vcgi.vermont.gov/gisdata/metadata/ElevationDEM_DEMHE0p7M2014.htm" target="_blank">Link to Metadata</a>) This metadata applies to the following collection area(s): Eastern VT 2014 0.7m and Hydro Enforced Digital Elevation Model (DEMHE) dataset. This metadata complies with the VT Geodata Portal format and applies to thematic layers with the same resolution (RESCLASS), e.g., 0p7m, 1m etc., and may include multiple data "collection" efforts. For the original vendor metadata containing specific details on each collections "point cloud" such as flight dates, nominal pulse spacing and RMSEz etc., see the "All Available Lidar" Product page: (http://vcgi.vermont.gov/warehouse/products/ALL-LDR_MIX_LIDAR_STATE_ALL). Available DEMs vary by collection and can include the following 'hydro treatment' DEMs: 1) Elevation*_DEM_*: ("pure" Bare Earth) - no treatments, i.e., a bare ground surface without objects like vegetation and buildings; 2) Elevation*_DEMHF_*: (DEM Hydro-Flattened)- Cartographic/Aesthetic enhancement of (topographic) surface by removal of Lidar artifacts in water. Constant elevation for waterbodies and suitable for contouring. Building voids remain due to cost; and 3) Elevation*_DEMHE_*: (DEM Hydro-Enforced): A (hydrologic) surface with drain connectivity used by engineers in Hydraulic and Hydrologic (H&H) modeling. NOT for traditional mapping (contours, etc.). Like DEM_HF but added Single Line Breaklines: Pipelines, Culverts, Underground Streams, etc. For an overview of the "Vermont Lidar Initiative" please see "http://vcgi.vermont.gov/lidar". For an overview on the various "hydro treatments" see the USGS powerpoint "Hydro Treatments of LiDAR-Derived DEMs" under the RESOURCES section of the Lidar Initiative homepage and for complete details see the appropriate section of the "Lidar Base Specification" (https://pubs.usgs.gov/tm/11b4/pdf/tm11-B4.pdf).; abstract: (<a href="http://maps.vcgi.vermont.gov/gisdata/metadata/ElevationDEM_DEMHE0p7M2014.htm" target="_blank">Link to Metadata</a>) This metadata applies to the following collection area(s): Eastern VT 2014 0.7m and Hydro Enforced Digital Elevation Model (DEMHE) dataset.
