FEMA Framework Basemap datasets comprise six of the seven FGDC themes of geospatial data that are used by most GIS applications
(Note: the seventh framework theme, orthographic imagery, is packaged in a separate NFIP Metadata Profile): cadastral, geodetic
control, governmental unit, transportation, general structures, hydrography (water areas & lines. These data include an encoding
of the geographic extent of the features and a minimal number of attributes needed to identify and describe the features.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
The DFIRM Database consists of community based vector files and associated attributes produced in conjunction with the hardcopy
FEMA FIRM. The published effective FIRM and DFIRM are issued as the official designation of the SFHAs. As such they are adopted
by local communities and form the basis for administration of the NFIP. For these purposes they are authoritative. Provisions
exist in the regulations for public review, appeals and corrections of the flood risk information shown to better match real
world conditions. As with any engineering analysis of this type, variation from the estimated flood heights and floodplain
boundaries is possible. Details of FEMA's requirements for the FISs and flood mapping process that produces these data are
available in the Guidelines and Specifications for Flood Hazard Mapping Partners. Horizontal accuracy was tested by manual
comparison of source graphics with hardcopy plots and a symbolized display on an interactive computer graphic system. Independent
quality control testing of FEMA's DFIRM database was also performed.

Completeness Commission
evaluation Method Description
Data contained in the DFIRM Database files reflect the content of the source materials. Features may have been eliminated
or generalized on the source graphic, due to scale and legibility constraints. With new mapping, FEMA plans to maintain full
detail in the spatial data it produces. However, older information is often transferred from existing maps where some generalization
has taken place. 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 analyses 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 analyses are used to generate
flood risk data only for developed or developing areas of communities. For 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.

ConceptualConsistency
measure Description
When FEMA revises an FIS, adjacent studies are checked to ensure agreement between flood elevations at the boundaries. Likewise
flood elevations at the confluence of streams studied independently are checked to ensure agreement at the confluence. The
FIRM and the FIS are developed together and care is taken to ensure that the elevations and other features shown on the flood
profiles in the FIS agree with the information shown on the FIRM. However, the elevations as shown on the FIRM are rounded
whole-foot elevations. They must be shown so that a profile recreated from the elevations on the FIRM will match the FIS profiles
within one half of one foot.
Data requests must include the full name of the community or county and the FIRM panel number(s) or the 7.5- minute series
quadrangle sheet area(s) covered by the request.
