NA Unknown NA File Geodatabase Feature Class All data was checked for topology using ArcGIS 9.2. All mapping features were checked for completeness by overlaying them on current orthophotography. Any missing features were identified and added to the dataset. All mapping was tested using >30 photo identifiable or targeted control points located on well-defined features distributed throughout the mapping area. Accuracy testing was performed to the National Map Accuracy Standards. The mapping complies with NMAS standards for 1" = 100' mapping. NSSDA accuracy was determined: tested 1.01 feet horizontal accuracy at 95% confidence level. Because most of the mapped features did not include well-defined features, map accuracy was determined by measurements of those features in the stereomodels used to compile the mapped features and by interpolation of the mapped features.
