Quality Edge-matching errors, overlaps and underlaps in coverage, and similar problems
are not corrected during digitizing or scanning and vectorizing the Q3 Flood
Data. Although FEMA has established no independent quality control/quality
assurance program for the Q3 Flood Data, the Q3 Flood Data files are
distributed only after they have passed checking routines contained in FEMA's
Q3QA Checking Software. The data are accompanied by documentation showing that
the files have been evaluated and passed. FEMA has established a User Support
mechanism through which any problems found with the data can be identified and
channeled back to FEMA for resolution.
