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.
Supplemental Information: The data have been reprojected to the Oregon Lambert (OGIC) projection for use in the Coastal Atlas.

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).
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).
