Data Quality Information
Logical Consistency Report
The shapefile is converted to SDC (Smart Data Compression) format using tools in ArcGIS. The SDC data set is then imported into a file geodatabase to verify, validate, and if needed repair the geometry.
Completeness Report
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
Horizontal Positional Accuracy Report
Horizontal positional accuracy is dependent on geographic area. In most areas, accuracy is between 5 and 25 meters (16 and 82 feet). In some areas, accuracy is off by up to several tens of meters (100 feet or more). In the poorest areas, accuracy is off by up to 100 meters (328 feet).
