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....

For more information about the development of the data please contact Mo Correll at Maureen.correll@maine.edu. "Tidal Marsh Vegetation Classification, DEM, 3m, Northeast U.S.", "Tidal Marsh Vegetation Classification, no DEM, 3m, Northeast U.S.", and "DEM Difference in Tidal Marsh Vegetation Classification, 3m, Northeast U.S." are products of the Saltmarsh Habitat and Avian Research Program (www.tidalmarshbirds.org).

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.

Slope is a measure of change in elevation. This dataset is derived from the following source: 30 meter Digital Elevation Model (DEM) for the Northeast (projected to NAD 83 Albers) that was created by mosaicking 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.
