Historic airboat use and change assessment using remote sensing and geographic information system techniques in Everglades National Park
MetadataShow full item record
The National Park Service (NPS) has a mandate of restoration and preservation of the lands for which it is responsible. As part of this mandate, resource managers of Everglades National Park (ENP) must take stock of current commercial and private airboat activities in the East Everglades Expansion Area and assess the impact of airboat use on the Everglades wetlands. Remote sensing and geographic information system (GIS) techniques were used to create digital databases of airboat trails from current and historical aerial photographs. These data were then used to derive statistics and produce trail maps which were used to assess airboat impact over time. Graph theory and GIS network analysis of the temporal trail database provide managers with a set of tools which, when combined with proposed scenarios for future airboat use, provide powerful analysis capabilities to minimize the potential impacts of that use.
