Land Characterization for Hydrologic Modeling in the Everglades
Introduction
The U.S. Geological Survey (USGS) is building hydrologic models of the Florida
Everglades for use in managing South Florida surface water flows for habitat
restoration and maintenance in the Everglades National Park and Water
Conservation Areas. Because of the low gradients present in the Everglades,
small variations in topography and differences in vegetation structural
characteristics are important factors in the distribution of surface water flow. At
the USGS, National Mapping Division (NMD), we are developing and applying
data collection, analysis, and modeling techniques to generate spatially
distributed information on topography and vegetation density.
Unfortunately, existing vegetation maps fail to meet our needs because they
were created with different requirements and technologies. Therefore, we are
developing our own techniques to map vegetation type on a regional scale. This
effort is detailed elsewhere in this volume (see Carter et al.). Here we focus on
the generation of elevation and vegetation density information using unique
collection and analysis techniques.
