Data_Quality_Information:
  Attribute_Accuracy
    Attribute_Accuracy_Report:
        Basin names are correct.
  Logical_Consistency_Report:
        Polygon topology exists.
  Completeness_Report:
        Data set is a complete representation of the drainage
        basins of the named streams in Montana.
  Positional_Accuracy
    Horizontal_Positional_Accuracy
      Horizontal_Positional_Accuracy_Report:
        Poor.  We know that some basin boundaries cross streams
        shown on 1:100,000 scale Digital Line Graphs.  Approximate
        accuracy of 1:2,000,000 scale data is 1000 meters.
