9.1.1.2. Everglades National Park GIS Program 
The Everglades National Park GIS (EVER GIS) is working with researchers and resource 
managers to develop Global Information System (GIS) data themes useful for ecosystem 
restoration and management of the Park. Data themes representing all aspects of the natural 
environment are contained in the GIS or are planned for the future. The data themes in the GIS 
cover a wide range of areas, scales and subjects. The availability of these themes varies. 
Current databases include distribution of foraging wading birds, deer, alligator nests, Cape 
Sable seaside sparrows, Florida panthers, manatees, and fires. Hydrological researchers are 
developing data themes representing actual and modeled water levels and depths. USGS 
1:24,000 quad data have been digitized for all of the south Florida park areas. Detailed 
vegetation maps for both before and after Hurricane Andrew are currently being developed 
using aerial photographs. A Florida Bay bathymetry map is nearing completion. The locations of 
all of the Park's physical monitoring stations are in the GIS. 
9.1.2. US Army Corps of Engineers 
The US Army COE has the responsibility of construction and maintenance of the system of 
canals in South Florida. 
9.1.2.1. Water Management Decision Support System 
The Water Management Decision Support System* of the Water Management and Meteorology 
Section monitors and regulates COE structures throughout the Central and Southern Florida 
project. Hydrologic and meteorological data is collected, processed, analyzed, and stored. The 
data includes water surface elevations, stream stages, reservoir elevations, and cumulative 
precipitation. The Section supports numerous Data Collection Platforms (DCP) installed at 
remote gaging stations which measure real-time data including water surface elevations, 
stream stages, reservoir elevations, and cumulative precipitation. The USGS maintains the 
DCP's and collects the data via the Geostationary Operational Environmental Satellite (GOES). 
9.1.2.2. Hydrographic and Topographic Surveys 
The Survey Branch, Engineering Division, conducts hydrographic and topographic survey of 
Corps of Engineers Projects throughout the Central and Southern Florida project. Both 
historical and current data is maintained in digital format.^ 
9.1.3. Environmental Protection Agency 
9.1.3.1. Everglades Mercury Study 
The Everglades Mercury Study (REMAP) of the Environmental Protection Agency (EPA) is 
designed to determine the extent and magnitude of Hg contamination in the Everglades 
ecosystem. It is an integral part of a larger interagency effort that is using ecological risk 
assessment as the organizing framework to evaluate critical mercury sources and pathways 
through the ecosystem and asses the relative risk to various biological components, including 
any relationship of eutrophication to Hg methylation. A probability-based random sampling grid 
is being used to obtain consistent estimates of Hg contamination over the 9600 km 2 area. Two
