DATA LINEAGE SUMMARY:

Contructed by FMRI
Based on data from the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) and data
from the Suwannee River and Southwest Florida Water Management Districts.

NWI maps are compiled through manual photointerpretation ( using Cartgraphic
Engineering 4X Mirror Stereoscopes) of NHAP or NAPP aerial photography
supplemented by Soil Surveys and field checking of wetland photo signatures.
Delineated wetland boundaries are manually transferred from interpreted
photos to USGS 7.5 minute topographic quadrangle maps and then manually
labelled. Quality control steps occur throughout the photointerpretation,
map compilation, and map reproduction processes.

Digital wetlands data are either manually digitized or scanned from
stable-base copies of the 1:24,000 scale wetlands overlays registered to the
standard U.S. Geological Survey (USGS) 7.5 minute quadrangles into
topologically correct data files using Wetlands Analytical Mapping System
(WAMS) software. Files contain ground planimetric coordinates and wetland
attributes. The quadrangles were referenced to the North American Datum of
1927 (NAD27) horizontal datum. The scanning process captured the digital
data at a scanning resolution of at least 0.001 inches; the resulting raster
data were vectorized and then attributed on an interactive editing station.
Manual digitizing used a digitizing table to capture the digital data at a
resolution of at least 0.005 inches; attribution was performed as the data
were digitized. The determination of scanning versus manual digitizing
production method was based on feature density, source map quality, feature
symbology, and availability of production systems. The data were checked for
position by comparing plots of the digital data to the source material.
