What does this data set describe?

Title:
H11076_UTM19_1MMBES.TIF: Color Shaded-Relief GeoTIFF Image Showing the 1-m Bathymetry Generated from NOAA Survey H11076 in Quicks Hole, Elizabeth Islands, MA (UTM Zone 19)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of the Massachusetts coastline, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. Interpretive data layers were derived from multibeam echo-sounder and sidescan sonar data collected in the vicinity of Quicks Hole, a passage through the Elizabeth Islands that extend in a chain southwestward off Cape Cod, Massachusetts. In June 2005, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconaissance survey.

Why was the data set created?

To release a color GeoTIFF image of the 1-m bathymetry generated from NOAA survey H11076 in Quicks Hole, Elizabeth Islands, Massachusetts.

How was the data set created?

  1. From what previous works were the data drawn?

    (source 1 of 1)
    .

    Type_of_Source_Media: DVD-ROM
    Source_Contribution:
    The original multibeam bathymetric data acquired with Reson 8101 and 8125 echosounder systems during NOAA cruise H11076 aboard the NOAA ship Thomas Jefferson were processed and exported as a hill-shaded color-encoded GeoTIFF (.tif) image in UTM Zone 19.

  2. How were the data generated, processed, and modified?

    Date: Unknown (process 1 of 1)
    The multibeam data was acquired in XTF (extended Triton data format), recorded digitally through an ISIS data acquisition system, and processed using CARIS HIPS (Hydrographic Image Processing System) software for quality control, to incorporate sound velocity and tidal corrections, and to produce a base surface at 1-m resolution. Among other formats (e.g. .txt and .gutm), the data were exported in GeoTIFF (.tif) format in UTM Zone 19. As part of the process creating the GeoTiff, the grid was hill-shaded (sun-illuminated) with the sun at an azimuth of 315, an altitude angle above the horizon of ~45, a verticle exaggeration of ~5x , and color encoded.
