Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.2.1350

Data_Quality_Information:
Logical_Consistency_Report:
The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE® to verify and validate 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.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal positional accuracy is difficult to determine since the boundaries may follow state, county, city, or other political boundaries. Still other times they may follow streets or other linear features in the database. Since these features are derived from different sources, it is not possible to give a single overall figure for horizontal accuracy.
