Geographic Information System

Data layers in this report are provided with geographic coordinates to       allow the data to be integrated into a Geographic Information System       (GIS).  A GIS is defined as a system of hardware and software to       support the display, manipulation, and analysis of spatial data for       mapping and complex data solving.  This package provides researchers       the ability to integrate, analyze, and map multiple datasets to help local       managers make decisions on the basis of the environmental effects of       proposed economic and social policies. 

Data layers archived here should not require additional processing to       be used in 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       with a different GIS software package or spheroid, but that it is not       necessary to do additional processing simply to use the data in its       minimum archive format. 

For users who don't 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 ArcExplorer is the       displaying of spatial data. The user will need to add the selected data       layers by using ArcExplorer's add data       button. 

Data Description 

This report includes links to several data layers (or themes) that can       be used to create views of the Edgartown Harbor study area. GeoTIFF files       produced from the NOAA sidescan-sonar and bathymetric surveys (combined       single-beam and multibeam) are provided in geographic and Universal       Transverse Mercator (UTM) Zone 19 WGS 1984 projections. GeoTIFFs of the       bathymetry are in color and are hillshaded; GeoTIFFs of the sidescan       imagery are in grayscale. ArcRaster grids of the combined single-beam and       multibeam bathymetric data are provided in 25-m resolution in geographic       and UTM projections. 

Ancillary vector data that are provided in the Geographic Coordinate       System in WGS84 datum consist of 1) polygon data layers that provide base       maps of the coastline for the Massachusetts GIS project area and an       outline of the survey area, 2) point data layers of the sediment data and       locations of bottom photos, and 3) navigation point and trackline files       for the seismic-reflection data. The photographic data are provided in       mid- and full-resolution JPEG image format; the seismic data are provided       in JPEG and SEG-Y formats. 

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 (for example, h11346_mb25m_utm19.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.       

The top level of this report on the DVD-ROM contains an ArcView project       file (h11346.apr) created in ArcView 3.3 and an ESRI ArcMap document       (h11346.mxd) created in ArcMap 9.2, but saved as an ArcMap 9.0/9.1       document to make it accessible to older versions of the software. 

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

A compressed (.zip), downloadable archive file containing the       components of the shapefile, grid, or image for each data layer is also       provided. Compressed, downloadable files were created by using the Windows       program WINZIP v8.0. Users who do not have software capable of       uncompressing the archived files may obtain a free version of the software       from Pkware, Inc.
