Orthoimagery Submission for Waukesha County, WI, USA - MIP Waukesha Portion Rock River RiskMap DFIRM Update
Dataset Identification:
Resource Abstract:
Digital orthographic imagery datasets contain georeferenced images of the Earth's surface, collected by a sensor in which
object displacement has been removed for sensor distortions and orientation, and terrain relief. Digital orthoimages have
the geometric characteristics of a map and image qualities of a photograph. (Source: Circular A-16, p. 16)

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
The digital orthophotography meets or exceeds National Map Accuracy Standards at a 1:12,000 scale (90% of well-defined points
must fall within 33.3 feet).
AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy
measure Description
Framework digital orthoimagery accuracy shall employ the National Standard for Spatial Data Accuracy (NSSDA), which implements
a statistical and testing methodology for estimating the positional accuracy of points in a digital geosptial data, with respect
to georeferenced ground positions of higher accuracy. The NSSDA uses root-mean-square error (RMSE) to estimate positional
accuracy. This accuracy shall reflect all uncertainties, including those introduced by geodetic control coordinates, compilation,
and final computation of ground coordinate values in the product.

ConceptualConsistency
measure Description
Waukesha County orthoimagery is based on the Universal Transverse Mercator grid system, Zone 16N. The orthophotography is
compiled to meet National Map Accuracy Standards at a 1" = 1000' or 1:12,000 scale (90% of well-defined points must fall within
33.3 feet). The orthophoto was converted to UTM 16N by the Wisconsin Department of Natural Resources.
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.
