Ecological Subsections

This geospatially explicit vector-based polygon dataset identifies 85 terrestrial ecological subsection delineations present in Southeast Alaska and the Tongass National Forest. Within each subsection one can expect to find a relatively consistent occurence and distribution of vegetation types. Due to the hydrologically-influenced geomorphology of Southeast Alaska specific key indicators of physiography, lithology, and surface geology were employed to systematically distinguish terrestrial ecosystems.

Rensselaer Plateau Boundary (2013), Rensselaer County, New York

Boundary of the Rensselaer Plateau as a physiographic unit. Physiography represents the study of landforms at regional levels, usually addressing combined patterns of topography, geology, soils, and dominant vegetation types.

Digital Elevation Model (DEM) of Northern Atlantic Coastal Plain topography and bathymetry with a horizontal resolution of 100 feet and vertical unit of 1 integer foot

This digital elevation model (DEM) for the Northern Atlantic Coastal Plain (NACP) from Long Island New York to northeastern North Carolina represents the elevation of the topographic and bathymetric surface at a uniform horizontal grid spacing of 100 feet and vertical units of 1 (integer) foot. The land-surface elevations are derived from U.S. Geological Survey 30-meter National Elevation Dataset (NED), and the bathymetric elevations are derived from 3 arc-second (90-meter-nominal) National Oceanic and Atmospheric Administration (NOAA) U.S. Coastal Relief Model (CRM). Horizontal coordinates are referenced to the North American Datum of 1983 (NAD 83) and vertical measurements are referenced to the North American...

Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Physiographic Provinces

This tabular data set represents the percent of physiographic provinces compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "Physiographic divisions of the conterminous U. S." produced by the United States Geological Survey (Fenneman, 1946). Units are percent. The "Physical Divisions of the United States," is based on eight major 1946 divisions, 25 provinces, and 86 sections representing distinct areas having common topography,...
