Data Quality Information:


Logical consistency report:
All DOQ header data and image file sizes are validated by the USGS by Tape Validation System (TVS) software prior to archiving in the National Digital Cartographic Data Base (NDCDB). This validation procedure assures correct physical format and field values for header record elements. Logical relationships between header record elements are tested.

Completeness report:
All DOQ imagery is visually inspected by the USGS for completeness to ensure that no gaps, or image misplacement exist in the  image area or in coveredge coverage. Images may be derived by mosaicing multiple images, in order to insure complete coverage. Source photography is leaf-off in deciduous vegetation regions. Void areas having a radiometric value of zero and appearing black may exist. These are areas for which no photographic source is available or result from image transformation from other planimetric systems to the Universal Transverse Mercator (UTM).
