Frequently-asked questions:

What does this data set describe?
Title:
fox-nhd-reach

Abstract:

The National Hydrography Dataset (NHD) is a national hydrographic data set which describes surface water resources in the United States. The Fox NHD-reach data represents a small portion of this extensive data resource. This data describes stream/river reaches in the entire Fox watershed (both Wisconsin and Illinois portions) and was created from the route.rch data in the Arc/Info coverage. Polyline M features were maintained in this version. For complete metadata for the NHD, visit http://nhd.usgs.gov/index.html

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • String (1471)

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

      The map projection used is Lambert Conformal Conic.

      Projection parameters:
      Standard parallel: 33.000000
      Standard parallel: 45.000000
      Longitude of central meridian: -89.500000
      Latitude of projection origin: 33.000000
      False easting: 2999994.000000
      False northing: 0.000000

      Planar coordinates are encoded using coordinate pair.
      Abscissae (x-coordinates) are specified to the nearest 0.001024.
      Ordinates (y-coordinates) are specified to the nearest 0.001024.
      Planar coordinates are specified in survey feet.

      The horizontal datum used is D_Clarke_1866.
      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.
