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.
(Source: Circular A16, p. 13) This data set contains 3-band natural color imagery from the National Agricultural Imagery Program
(NAIP). NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S. A primary goal
of the NAIP program is to enable availability of ortho imagery within one year of acquisition. The source files are 1 meter
ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 5 meters of reference digital
ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP) or from NAIP. The tiling format of NAIP imagery
is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP imagery is formatted to the
UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. This file was generated by
compressing NAIP imagery that cover the county extent. MrSID compression was used. Target values for the compression ratio
are (15:1). (Note: The Minnesota Geospatial Information Office (MnGeo) has created this metadata record to describe the entire
NAIP2009 dataset, using information from Farm Service Agency metadata. Each county file is accompanied by the original FSA
metadata for that county.)

The Basemap datasets reflect the reference features (i.e., roads, streets, hydrographic features, political jurisdiction boundaries)
needed by users to locate properties on FIRMs. (Source: Guidelines and Specifications Vol 1, p. 68) NAIP imagery is available
for distribution within 60 days of the end of a flying season and is intended to provide current information of agricultural
conditions in support of USDA farm programs. For USDA Farm Service Agency, the 1 meter GSD product provides an ortho image
base for Common Land Unit boundaries and other data sets. The 1 meter NAIP imagery is generally acquired in projects covering
full states in cooperation with state government and other federal agencies who use the imagery for a variety of purposes
including land use planning and natural resource assessment. NAIP is also used for disaster response often providing the most
current pre-event imagery.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
The NSSDA is used to report the horizontal accuracy of the base map data used by FEMA to produce a FIRM. The NSSDA uses radial
accuracy (Accuracy) to report the radius of a circle of uncertainty, such that the true or theoretical location of a point
falls within that circle 95 percent of the time. (Guidelines and Specifications Vol 1, p. 70)
Completeness Commission
evaluation Method Description
The Basemap datasets represents all the features utilized during the study mapping process to spatially position the DFIRM
information and highlights the specific prioritization process laid out in the Guidelines and Specifications Vol 1, p. 69
in their selection for use. The final selection criteria, and rational for inclusion should be outlined here, along with rational
for exclusion of use of specific base map datasets if applicable.

ConceptualConsistency
measure Description
Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon
tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate
features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the
point of intersection. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. Tests
for logical consistency are performed by DFIRM tools topology verification software.
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.
