Geospatial_Data_Presentation_Form: raster digital data

Other_Citation_Details:

A fundamental database for GIS/LIS applications is gridded elevations, upon which digital maps of rivers, infrastructure and other geographic information can be overlain. While digital elevation models (DEMs) of the coastal states are available through the US Geological Survey (USGS), until now there has been no comparable product for offshore elevations aside from custom grids generated by individual investigators. Our team at NGDC is taking advantage of the recently restructured NOS Hydrographic Database, and the maturation of software for constructing, managing, accessing and viewing gridded hydrographic data, to assemble a gridded database of coastal zone elevations that complements and enhances the USGS 3-arc-second DEMs. This Coastal Relief Gridded database provides the first comprehensive view of the US Coastal Zone; one that extends from the coastal state boundaries to as far offshore as the NOS hydrographic data will support a continuous view of the seafloor. In many cases, this seaward limit reaches out to, and in places even beyond the continental slope. Data sources include the US National Ocean Service and the US Geological Survey. Volumes 3 through 5 also include bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project.

Description:

Abstract:

This data set includes sea floor topography of the area offshore of New York and New Jersey from the National Oceanic and Atmospheric Administration Coastal Relief Model. The data set is derived from historical measurements of sea floor depth and is gridded at 90 m spatial resolution.

Purpose:

The purpose of this project is to map the surficial geology of the sea floor of Historic Area Remediation Site (HARS) and changes in surficial characteristics over time. This GIS project presents multibeam and other data in a digital format for analysis and display by scientists, policy makers, managers and the general public.

Other_Citation_Details:

The first elevation grids constructed for the database formed volumes one and two of the NGDC Coastal Relief Model CD-ROM series. These volumes collectively covered an area of the US coastal zone that extends from 48° N to 31° N latitude, encompassing the land areas and surveyed offshore areas of the coastal states from Maine to Georgia. In October, 2001, volumes three, four, and five were released covering the coast of Florida and the US Gulf of Mexico coastal zone (see illustration at upper left). The gridded database will eventually encompass the coastal zone of the continental US, Alaska, Hawaii and Puerto Rico. However, the US coastal zone is being gridded in sections due to the immense volume of data involved in this project. The grids of the eastern US coastal zone (excluding Florida) are the first in a series of gridded data sets that are being compiled for the US coastal zone. The data sets are being systematically assembled proceeding clockwise around the continental US. The next datasets to be released will be of the western US coastal zone, encompassing California, Oregon and Washington, of the Great Lakes and their bordering states, and then of Alaska and the Aleutian Islands. Data sets of Hawaii and Puerto Rico will be included amongst these as well.

Process_Step:

Process_Description:

The data for these data layers were extracted from the Geodas CDROM Volumes 1 and 2. These CD's are produced by the National Oceanic and Atmospheric Administration, National Geophysical Data Center in Boulder, CO. Spatially referenced depth values were exported into an ASCII raster file, which was then imported into Arcview Spatial Analyst to create gridded bathymetry with a cell size of 90 by 90 meters. The grid was then contoured at 20 meter intervals from 20 to 200 meters.

The ASCII raster file was also used to generate a sunilluminated image with software from University of New Brunswick, which had an elevation angle of 45 degrees and was illuminated from the north with an exagerration of 100 times. This image was then converted into a grid to be used as a brightness theme for the bathymetry grid.
