  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 earth"s surface using geographic projection
      and decimal degree coordinate system.  The 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 
      puchase 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, 
      the risk zones shown on the FIRMs are the basis for the establishment of 
      premium rates for flood coverage offered through the NFIP.
        Q3 Flood Data files are intended to convey certain key features from the
      existing hard copy FIRM to provide users with automated flood risk data.
      Edge-matching errors, overlaps and deficiencies in coverage, and similar
      problems are not corrected during digitizing or post-processing.  
        These data may be used to locate Special Flood Hazard Areas (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 the FEMA Flood Insurance Rate Maps (FIRMS).  The attribute
      definitions may be found in the "Q3 Flood Data Specfications".  Attribute
      accuracy was tested by manual comparison of source graphic with hardcopy
      plots and a symbolizied 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).
    Quantitative_Attribute_Accuracy_Assessment
      Attribute_Accuracy_Value:  See Explanation
      Attribute_Accuracy_Explanation:  Attribute accuracy is described, where 
        present, with each attribute defined in the Entity and Attribute Section.
 
  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:  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 reflect 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
      hydrological and hydraulic analysis.  Both detailed and approximate
      analyses are employed.  Generally, detailed anaylses 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.
        The Q3 Flood Data coverages may be derived from DFIRM-DLGs, from FIRM-
      DLGs, from FIRMs digitized previously for emergency applications, or may
      be newly created files.  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 their 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 on past
      floods and are described by a unique attribute code that distinquishes
      them from areas of 1% annual chance of flooding derived from FIRMs.
        Flood Insurance Rate Maps 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 FIRM.  To obtain the latest information, contact
      the address listed under distributor.
 
  Positional_Accuracy
    Horizontal_Positional_Accuracy
      Horizontal_Positional_Accuracy_Report:  Specifications for the digitizing
        of FIRMs to create the 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
        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 (i.e. 1:24000).

 Process_Step
   Process Description:  Q3 Flood Data format was produced by either
        scanning or manually digitizing a hardcopy version of the graphic
        materials.  The scanning process captured the digital data and the
        resulting raster data was vectorized and attributed on an
        interactive editing station.  Manual digitizing used a digitizing
        table to capture the digital data; attribution was performed either
        as the data was 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 control points corresponding to the four
        corners of the map were used for registration during manual
        digitizing.  A projection 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.  The ARC/INFO coverage of the Q3 Flood Data was
        generated, and it was also used to create the Q3-DLG file.  The Q3
        Flood Data was checked for position and attribute accuracy by
        comparing plots of the digital data to the graphic source and by
        symbolizing display on an interactive computer graphic system.
        Selected attributes that could not be visually verified were
        individual 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 was projected into a
        geographic grid system using decimal degree latitude and longitude
        coordinates and then converted into an ARC/INFO export file and 
        MapInfo native table files.  In addition, the ARC/INFO coverage in
        UTM coordinates was converted into a Digital Line Graph file.  All
        final files were checked for logical consistency and completeness.

  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
