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.
