Integrated multimedia approach to the utilization of an Everglades vegetation database

Abstract

An approach for integrating multimedia data with a geographic information system (GIS) database was developed for an area corresponding to the U.S. Geological Survey (USGS) Long Pine Key and Pa-Hay-Okee Lookout Tower 1 :24,000scale topographic quadrangles in Everglades National Park. The multimedia database contains descriptive text, ground photographs, digital video clips, and audio segments highlighting the characteristics of Everglades plant communities, individual species, and invasive exotics, as well as plant-anima1 interactions, hurricane damage, and post-fire vegetation succession. It is linked to a GIS database that includes detailed vegetation maps, SPOT panchromatic imagery, and scanned National Aerial Photography Program (NAPP) 1:40,000-scale color-infrared (CIR) aerial photographs. The integrated multimedia approach was implemented in two steps: (1) an interactive multimedia system designed to manipulate multimedia information such as hypertext, hyperlinks, scanned photographs, digital video, and sound was developed in a Microsoft Visual Basic programming environment; and (2) a CIS application program to manipulate spatial data was constructed using Visual Basic and Environmental Systems Research Institute (ESRI) Mapobjects software. The interactive multimedia approach provides a unique way to represent geographic features and associated information on interrelationships between flora, fauna, and human activities in Everglades National Park.
