Description
Abstract: The Q3 Flood Data are derived from the
Flood Insurance Rate
Maps (FIRMs) published by the Federal
Emergency Management Agency (FEMA).
The file is georeferenced to the earth's
surface using the Universal
Transverse Mercator (UTM) projection
and a zonal coordinate system
(units in meters). Specifications
for the horizontal control of Q3
Flood Data files are consistent with
those required for mapping at a
scale of 1:24000.
Purpose: The FIRM is the basis for floodplain
management, mitigation,
and insurance activities for the National
Flood Insurance Program
(NFIP). Insurance applications
include enforcement of the
mandatory purchase requirement of the
Flood Disaster Protection Act,
which "requires the purchase of flood
insurance by property owners
who are being assisted by Federal programs
or by Federally supervised,
regulated, or insured agencies or institutions
in the acquisition
or improvement of land facilities located
or to be located in
identified areas having special flood
hazards" (Section 2 (b) (4)
of the 1973 Flood Disaster Protection
Act). In addition to the
identification of Special Flood Hazard
Areas (SFHAs), the risk zones
shown on the FIRMs are the basis for
the establishment of premium rates
for flood insurance coverage offered
through the NFIP.
Q3 Flood Data files
convey certain key features from the existing
hard copy FIRM. Edge-matching
errors, overlaps and deficiencies in
coverage, and similar problems are not
corrected during digitizing or
post-processing. The Q3 Flood
Data files are inteded to provide users
with automated flood risk data that
may be used to locate SFHAs. More
detailed information may be obtained
from the paper FIRM.

Data
Quality Information
Attribute Accuracy
Attribute Accuracy Report: The Q3 Flood Data
are countywide vector
files derived from FEMA FIRMs. The attribute
definitions may be found
in the "Q3 Flood Data Specifications". Attribute
accuracy was tested by
manual comparison of source graphic with hardcopy
plots and a symbolized
display on an interactive computer graphic system.
Selected attributes
that could not be visually verified were individually
queried. In
addition, an ARC/INFO Arc Macro Language (AML) software
program was
applied to the dataset to test the attributes against
a master set
of valid attributes for the specific data category
and a complete set
of valid attribute combinations. (See also
Entity Attribute Information.)
Logical Consistency Report: Polygon and chain-node topology
are present.
Certain node-area-line relationships are collected
or generated to
satisfy topological requirements. Some of
these requirements
include the following: lines must begin and end
at nodes, lines must
connect to each other at nodes, lines do not extend
through nodes, left
and right areas are defined for each line segment
and are consistent
throughout the files, and the lines representing
the limits of
the file neatlines are free of gaps. Tests
of logical
consistency were performed by ARC/INFO software
modules. Check
plots were made to test for leaks in all internal
polygons.
Completeness Report: Data completeness for Q3 Flood Data files
reflects the content of the source graphic.
Features may have been
eliminated or generalized on the source graphic,
due to scale and
legibility constraints.
Flood risk data are developed
for communities participating in
the NFIP for use in insurance rating and for floodplain
management. Flood hazard areas are determined
using statistical
analysis of records of river flow, storm tides,
and rainfall;
information obtained through consultation with the
communities:
floodplain topographic surveys; and hydrologic and
hydraulic
analysis. Both detailed and approximate analyses
are employed.
Generally, detailed analyses are used to generate
flood risk data
only for developed or developing areas of communities.
For
undeveloped areas where little or no development
is expected to
occur, FEMA uses approximate analyses to generate
flood risk
data. Typically, only drainage areas that
are greater than one
square mile are studied.
Q3 Flood Data may be derived from
DFIRM-DLGs, from FIRM-DLGs, or from
FIRMs digitized previously for emergency applications,
or they may be newly
created. In Q3 Flood Data derived from older
data sets, certain items
may not have been captured or may have been captured
differently from
the current Q3 Flood Data specifications.
In some cases, preliminary FIRM
data have been included in the Q3
Flood Data files. These data have been provided
to the community for
review and comment, and may be subject to change
before their
final publication date. In addition, in some
cases, areas designated
as Flood Prone Areas on maps prepared by USGS and
FIA have been included
in the Q3 Flood Data files. These areas were
delineated based on
available information of past floods and are described
by a unique
attribute code that distinguishes them from areas
of 1% annual chance
flooding derived from FIRMs.
FIRMs continually undergo revisions
and updates. Some of these
revisions are effected by letter (Letter of Map
Revision [LOMR],
Letter of Map Amendment [LOMA]). Q3 Flood
Data may not reflect
the most current information or information that
is not mappable
at the publication scale of the FIRM. To obtain
the latest information,

Positional Accuracy
Horizontal Positional Accuracy
Horizontal Positional Accuracy Report:
Specifications for the
digitizing of FIRMs
to create Q3 Flood Data are consistent
with those requirements
for mapping at a scale of 1:24000.
Horizontal control
of Q3 Flood Data was established using USGS
quadrangle maps at
1:24000 or other standard scales. Users should
assess the horizontal
positional accuracy of the Q3 Flood Data with
regard to the selected
base map sources and the requirements
of their application.
With increased frequency, large-scale spatial
data sets are becoming
widely available for computer-based geographic
information systems.
Q3 Flood Data may be used in combination with
other digital spatial
data; however, users should be aware that scalar
enlargements do not
enhance the relative accuracy of the Q3 Flood
Data.

Process Step
Process Description: Q3 Flood Data were produced by either
scanning and
vectorizing or manually
digitizing a hardcopy version of the graphic
materials. The scanning and vectorization process captured
the digital
data as raster data that
were vectorized and attributed on an
interactive editing station.
The manual digitizing process used a
digitizing table to capture
the digital data; attribution was performed
either as the data were digitized or on an interactive edit station
after
the digitizing was completed. The determination of the
production methodology
was based on various criteria, including availability of production
systems.
Four to nine control points per FIRM panel were used for registration
during manual digitizing.
A projective transformation was performed
on the coordinates used
in the data collection and editing systems to
register the digital data
to the Universal Transverse Mercator (UTM)
grid coordinates.
An ARC/INFO coverage of the Q3 Flood Data was
generated and used to create
the Q3-DLG file. The Q3 Flood
Data were checked for position
and attribute accuracy by comparing
plots of the digital data
to the source graphic and by symbolized
display on an interactive computer system. Selected attributes
that
could not be visually verified were individually queried. In
addition,
an ARC/INFO Arc Macro Language (AML) software program was
applied to
the dataset to test the attributes against a master set of valid
attributes
for the specific data category and a complete set of valid attribute
combinations. Source graphics were revised to reflect updates
effected by Letters of Map Change (Letter of Map Revision [LOMR],
Letter of Map Amendment [LOMA]). These revisions were included
in
the Q3 Flood Data if they were mappable at the publication scale
of
the source graphic. Once final, the ARC/INFO coverage is
projected into a
geographic grid system, using decimal degree latitude and longitude
coordinates and then converted into an ARC/INFO Export file.

Information
Overview Description
Entity and Attribute Overview: In addition
to locational and topological
information, Q3 Flood data elements
are explicitly encoded using
attribute items. Each attribute
item identifies characteristics about
the Flood Hazard Area, COBRA,
Floodway, Political Jurisdiction,
Quadrangle, or FIRM panel.
All polygon data elements may be
encoded with one or more feature
characteristics.
Entity and Attribute Detail Citation: The FEMA "Q3
Flood Data

description of each attribute code
and a reference to other relevant
information.
