To attain a better estimate of accuracy, a formal re-evaluation of the area would be necessary to see if there are areas where discrepancies exist. Logical_Consistency_Report: Quality assurance was performed on the data entry process. Data was cross checked with the field notes. All points have geographic coordinates and all attribute values assigned to them. Completeness_Report: There are no known omissions in the data set. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal positional accuracy is based on the accuracy of the GPS navigational unit used in the aerial survey. Actual accuracy percentage is not known.
