The mapping was carried out using a Simrad Subsea EM 1000 Multibeam Echo Sounder on the Frederick G. Creed on four cruises conducted between 1994 and 1998. The mapping was conducted in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and with support from the Canadian Hydrographic Service and the University of New Brunswick. The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) project that presents images and grids of bathymetry, shaded relief bathymetry, and backscatter intensity data from these surveys that will serve the needs of research, management and the public. Purpose: This data set provides shaded-relief topography of eastern Massachusetts for use on USGS Map I-2734. It has been color-coded with a green color scale.

NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data with NAD83 datum for the conterminous US and Hawaii, and 1:63,360-scale DEM data with NAD27 datum for Alaska. PURPOSE Geospatial elevation data are utilized by the scientific and resource management communities for global change research, hydrologic modeling, resource monitoring, mapping, and visualization applications. Process_Step: Process_Description: An image showing shaded relief topography, colored by elevation, was created from the grayscale topography GeoTIFF image (land_dtmgs30m.tif) and the shaded relief GeoTIFF image (land_srelief30m.tif) with the following steps in Photoshop: Open the topography and shaded relief tiffs Select the topography tiff, and select image/mode/indexed color Select image/mode/color table/load DTMcolorMap10greens.act (located in the color tables folder of the GIS) Select image/mode/RGB color Select image/apply image/source, choose shaded relief tiff Select image/mode/indexed color; palette (select local (selective)), colors (256), forced (none), transparency (off ), options (none). Save as .tiff; image compression (select none), byte order (select Macintosh) Source_Used_Citation_Abbreviation: land_dtmgs30m.tif Source_Used_Citation_Abbreviation: land_srelief30m.tif Source_Produced_Citation_Abbreviation: land_green30m.tif Process_Contact: Contact_Information: Contact_Organization_Primary: Contact_Organization: U.S. Geological Survey Contact_Person: Tammie Middleton Contact_Position: Operational Geologist Contact_Address: Address_Type: mailing and physical address Address: 384 Woods Hole Rd.
