- Abstract:
-
The U.S. Geological Survey has conducted geologic mapping to characterize the sea floor offshore of Massachusetts. 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 image provides shaded-relief topography of eastern Massachusetts for use on USGS Map I-2734.

The USGS National Elevation Dataset (NED) has been developed by merging the highest-resolution, best-quality elevation data available across the United States into a seamless raster format. 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.
- Process_Step:
-
- Process_Description:
-
Convert National Elevation Data (NED) set into shaded relief image at 30-m resolution. This was accomplished by gridding the XYZ values from the NED data set for Boston and Cape Cod using software developed by the Ocean Mapping Group (www.omg.unb.ca/~jhc/SwathEd.html).
1. Download data from National Elevation Dataset website (<http://gisdata.usgs.net/ned>) in ESRI grid format. Crop data to boundaries of USGS Map I-2734.
2. Create a 30-m grid of the NED data using SwathEd routine weighgrid to generate a binary grid compatible with the UNB software. The grid is mapped in the mercator projection.
3. Create a shaded relief image of the bathymetry using SwathEd routine addSUN (sun elevation of 45 degrees from 350, vertically exaggerating 4 times).
Command line: addSUN -elev 45 -azi350 -vert_exag 4.0 gridFile.r4 filename.shade
4. Use a two-point linear contrast stretch to enhance the shaded relief image:
Command line: stretchacres -low 105 -high 255 -in filename.shade -out filename_shade.stretch
5. Convert the contrast-stretched shaded relief image from SwathEd format to a tiff file using the netpbm utilities (<http://netpbm.sourceforge.net/>):
Command line: rawtopgm -headerskip 1024 image_width image_height filename_shade.stretch | pnmtotiff -none - > filename.tif
6. Create an ESRI world file (tfw) for the shaded relief tiff image for import to ArcView or ArcGIS. Copy bounding box and resolution information from the jview program output to the tfw file.
Command line: jview filename_shade.stretch
