I'm not familiar with the FloodMap product, but here is some info on FEMA's Q3
Flood data. The following excerpts were taken from the Q3 Flood Data Users
Guide, which is available at http://www.fema.gov/msc/q3flooda.htm
"The hardcopy FIRMs from which the Q3 Flood Data vector data are extracted
contain no horizontal control. The horizontal controlling of these data is
typically performed by fitting the vectors to a georeferenced raster or vector
7.5-minute quadrangle file. The horizontal control of Q3 Flood Data vector data
is consistent with that required for mapping at the scale of 1:24,000."
"The Q3 Flood Data do not replace the existing hardcopy FIRM or, if one exists,
DFIRM product. The product has been designed to support planning activities,
some Community Rating System (CRS) activities, insurance marketing, and mortgage
portfolio review. It does not provide base flood elevation information; thus,
it has limited application for engineering analysis, particularly for site
design or rating of flood insurance policies for properties located within
SFHAs."
"Q3 Flood Data are not tied to a base map, are not used to produce a new version
of the hardcopy FIRM, and are not subjected to community review. Q3 Flood Data
are intended to provide users with automated flood risk data suitable for
determining whether features are within or outside the SFHA."
For the reasons stated in the above paragraph, the Q3 flood data does not have
the same legal standing as the hardcopy Flood Insurance Rate Maps.

Hi All,
MapInfo just announced the availability of FloodMap, a high quality up-to date
digital version of the FEMA Q3 data produced by Transamerica Flood Hazard
Certification. A couple of questions:
We deal extensively with the engineering and surveying community. When I
mentioned this to several of our clients in SC, they stated that even though
these maps are probably much more accurate, they are constrained by law to use
FEMA generated data so they would need to get a reading as to whether this would
be legal data. I would assume the same conflict would arise from any other
business that is betting money on FEMA certification.
When I was dealing directly with Transamerica on this data, they were adamant
that their name not be associated with any data resale. The litigation hazard
of data of this nature being improperly used was tremendous. While they were
willing to talk about sharing the data for sale, they made it very clear that
any certifications or serious deliberations based on data with the transamerica
name would only be made by their certification people.
Any comments from those of you who might have worked in this area?
Best,
John D. Haynes
