What does this data set describe?

    Title:
    USGS Open-File Report 00-304, Chapter 12, Eastern Long Island Sound - Selected Bottom Photographs of Sedimentary Environments in Eastern Long Island Sound
    Abstract:
    This report chapter presented photographs taken in the vicinity of Niantic Bay, Connecticut during March 1996 aboard the RV John Dempsey with a still camera attached to a Van Veen grab sampler (Poppe and others, 1998a). The still camera was a Photosea model 1000; Kodak Professional Color Negative ASA 400 film was used. Station identifiers, navigation, and descriptions of these photographs were given in Table 1 of this chapter; ancillary sediment data are supplied in Poppe and others (1998b). Descriptions of bottom video collected concurrently with the still photography are available in Poppe and others (1996) and for viewing at the Woods Hole Science Center.

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (18)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.
