Frequently-anticipated questions:

What does this data set describe?

Title: River Discharge to the Coastal Ocean: A Global Synthesis
Abstract:
This is the location of the mouths of the rivers in the Milliman and Farnsworth (2010) database. Each location has associated with it information regarding the characteristics of the watershed and the water and sediment discharge.

    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 (1531)

    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 D_WGS_1984.
      The ellipsoid used is WGS_1984.
      The semi-major axis of the ellipsoid used is 6378137.000000.
