Data Sources

Topographic data were obtained from the U.S. Geological Survey (USGS) - National Mapping Division. The data were collected at a 400-meter spacing via helicopter using differential global positioning system technology. Daily water-surface elevation data were supplied by a variety of sources. Water-surface elevation and topographic data were converted to the Universal Transverse Mercator coordinate system, North American Datum 1983, and North American Geodetic Vertical Datum 1988, in meters.

Discharges from control structures S-332 and S-175 (obtained from the SFWMD) are included in the model to help characterize regional responses to boundary inflows. Also, measured depths from USGS field efforts in 1997 and 1999 are used to estimate model accuracy.

Precipitation data are included in the model to help determine the relationship between local rainfall events and regional inundation depths and patterns. Data from 10 meteorological stations were obtained from the ENP and the USGS. The general wet and dry seasons are from June through November and December through April, respectively.
