Data Quality Information
Attribute Accuracy Report
All data has been reviewed for correct application of attributes and is accurate to current conditions.
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
The level of detail for each feature is generally better than what is traditionally utilized in a 1:500,000 scale product. The positional accuracy is typical of a 1:100,000 scale map, or +/-50 meters 90% of the time.
