- 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.
