### Combined Multibeam Bathymetry Data from Rhode Island Sound and Block Island Sound – A Regional Perspective

This  report contains GIS data in vector and raster format. The vector data are  provided in shapefile format compatible with Esri ArcGIS  software. These data are in the World Geodetic System of 1984 (WGS 84)  geographic coordinate system. The raster data are provided in GeoTIFF format  and Esri binary grid format. These raster data are provided in the WGS 84  geographic coordinate system and a Universal Transverse Mercator (UTM) Zone 19  projection on North American Datum of 1983 (NAD 83). The WGS 84 and NAD 83  datums were used for consistency with earlier reports. Data layers provided as  supplement to this report should not require additional processing to be used in  Esri software. 

For  users who do not have the Esri software or a compatible GIS data browser  available on their computer, a free viewer, ArcGIS Explorer, is available from  Esri. The key functionality of ArcGIS Explorer is to display spatial data. The  user will need to add the selected data layers by using the add data function  of ArcGIS Explorer. 
Data Description 
This  report includes links to several data layers (or themes) that can be used to  create views of the study area in Block Island and Rhode Island Sounds.  GeoTIFFs of the bathymetry are provided as color hill-shaded relief images.  ArcRaster binary grids of the multibeam bathymetric data are included at a 4-m  resolution.

Ancillary  vector data consist of polygon data layers that provide base maps of the  coastline for the Rhode Island GIS project area and an outline of the study  area. 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., ricomb_4mmb_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  root level of this report on the DVD–ROM contains an Esri ArcMap document  (ricomb**_**utm.mxd) created in ArcMap 9.3, 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 Hyperlink Text Markup Language (HTML), a frequently asked  questions (FAQ) HTML, and text versions. Selecting associated metadata files  from links in the catalog 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 WinZip 8.0 for Microsoft Windows.
