Product Description: Originally created for a specific, in-house project, these "hydrologically corrected" DEMs and derived data are being made available to support other hydrologic modeling activities. Collectively referred to as the "VT Hydro DEMs" this dataset was interpolated from: 1) the Vermont Mapping Program (VMP) "x, y, z" data known as the "DEM points" (originally used to georectify the state digital orthophotos); and 2) VHD surface water features. The primary advantage of this dataset over others, e.g., all of the National Elevation Datasets (NED), is that the VHD features have been "hydro enforced" into the elevation surface so that they are coincident. This data should not be confused with the USGS "1/3 arc second" 10m NED data. A single, statewide DEM (ElevationDEM_VTHYDRODEM) is also available on this product and on the Vermont Geographic Information System (VGIS) but the "derived data" exist at the subbasin level only on this DVD.
