Digital Elevation Model (DEM), Northern Appalachian This dataset represents elevation for the Northern U.S. and Canada. This Digital Elevation Model (DEM) was created by mosaicing two datasets: 1. U.S. Geological Survey's (USGS) 30 meter National Elevation Dataset (NED) , ~1 arc-second data that is updated over large areas by integrating the 10 meter or better source data (where available), re-sampled to 1 arc-second. 2. The Canadian Digital Elevation Data, Level 1 (CDED1) The Center of Topographic Information (CTI) jointly produces the CDED with federal, provincial, and territorial government agencies as well as the private sector. The CDED consists of an ordered array of ground or reflective surface elevations, recorded in meters, at regularly spaced intervals....

NHDPlusV2 includes derivation of “elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first broadly applied in New England, and thus dubbed "The New-England Method". This technique involves "burning-in" the 1:100,000-scale NHD and building "walls" using the national Watershed Boundary Dataset (WBD)” (USEPA and USGS 2012)....

National Hydrology Datasets, Fewer tags Shaded Relief, Northeast U.S. and Canada This dataset represents a shaded relief, or hillshade, for the Northern U.S. and Canada. This shaded relief raster was created from a 30 meter Digital Elevation Model (DEM) using the ArcMap geoprocessing tool "hillshade". The DEM consists of two mosaiced datasets: 1. U.S. Geological Survey's (USGS) 30 meter National Elevation Dataset (NED) , ~1 arc-second data that is updated over large areas by integrating the 10 meter or better source data(where available), re-sampled to 1 arc-second. 2.
