This report contains several data layers (or themes) that can be used to create views of the Great Round Shoal Channel study area. GeoTIFFs produced from the National Oceanic and Atmospheric Administration (NOAA) multibeam bathymetric and sidescan-sonar surveys are provided in geographic and Universal Transverse Mercator (Zone 19) and in color and grayscale versions. Grids of the multibeam bathymetric data, which are provided in original and hill-shaded versions, are also provided in geographic and Universal Transverse Mercator. Available vector data consists of polygon data layers that provide the coastline for the Massachusetts GIS project area and interpretive data layers.

Data layers are provided with geographic coordinates to allow the data to be integrated into a Geographic Information System (GIS). This integrated package provides researchers the ability to integrate, analyze and map the various datasets to help with economic and social policy-making decisions regarding the environment.

Data layers archived here do not require additional processing to be utilized within the Environmental Systems Research Institute's (ESRI) ArcView and ArcGIS software. This does not mean that a user will not wish to do additional processing, especially if utilizing a different GIS software package or spheroid, but that it is not necessary to do additional processing simply to utilize the data in its minimum archive format

For those who do not have the ESRI software or a compatible GIS data browser available on their computer, a free viewer, ArcExplorer, is available from ESRI. The key functionality of this software is the viewing of spatial data, but the user will need to add the selected data layers by using ArcExplorer add data button.

Each GIS data layer from this publication is cataloged below for easy access. The individual data layers are described below and include the GeoTIFF, grid, or shapefile name (e.g. h11079_3mutm19_mb.tif) which is linked to a browse graphic showing the data layer extent and coverage. Selecting the data layer name will result in the browse graphic being displayed in a separate browser window.

Federal Geographic Data Committee (FGDC) metadata for the individual data layers is provided in a text version. Selecting associated metadata files from the table below will open the information in a new browser window.

A 'zip' compressed, downloadable archive file containing the components of the ArcView shapefile for each data layer is also provided. Compressed downloadable files were created using the Windows program WINZIP v8.0. For those users who do not have software capable of uncompressing the archived zip files, they may obtain a free version of the software from Winzip Computing, Inc. or Pkware, Inc.
