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 0.1234. Longitudes are given to the nearest 0.1234. Latitude and longitude values are specified in Decimal degrees.

7. How does the data set describe geographic features?

Who produced the data set?

1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
   • Larry J. Doyle
   • Thomas N. Sparks

2. Who also contributed to the data set?

   Please review the cross reference information for the original data set credit to Doyle and Sparks (1980), and Chris Jenkins for digitizing sample locations and entering the data from the source report.
