PE&RS February 1999

Cover Image

This month’s cover displays a digital vegetation map database of Everglades National Park, Big Cypress National Preserve, Biscayne National Park, and the Florida Panther National Wildlife Refuge - an area of more than 10,000 km² - registered to a geocoded SPOT panchromatic image mosaic of south Florida. The vegetation database was compiled from color-infrared aerial photographs by the Center for Remote Sensing and Mapping Science, The University of Georgia, working in conjunction with the South Florida Natural Resources Center, Everglades National Park. A companion database is being compiled by the South Florida Water Management District for the bordering Water Conservation Areas. These databases are in Arc/Info format and contain 89 plant communities classified according to the new Everglades Vegetation Classification System. This issue of Photogrammetric Engineering & Remote Sensing focuses on the production and application of the Everglades vegetation databases and maps.

153 Foreword
Roy Welch

155 The Everglades: A Perspective on the Requirements and Applications for Vegetation Map and Database Products
Robert F. Doren, Ken Rutchey, and Roy Welch

The vegetation mapping efforts described herein provide a baseline for extablishing trends and monitoring changes related to the restoration and preservation of the Everglades.

163 Mapping the Everglades
Roy Welch, Marguerite Madden, and Robert F. Doren

Detailed vegetation and ORV trail databases and associated 1:15,000-scale maps keyed to U.S. Geological Survey 7.5-minute topographic quadrangles were developed for the Everglades using integtrated Global Positioning System, remote sensing, and geographic information system technologies.

171 Photointerpretation Key for the Everglades Vegetation Classification System.
Marguerite Madden, David Jones, and Les Vilchek

The key is used to train new photointerpreters, as well as to provide users of the vegetation database with further information on photo details and field characteristics associated with Everglades vegetation classes.

179 Mapping Exotic Vegetation in the Everglades from Large-Scale Aerial Photographs
Cheryl M. McCormick

Detailed maps were produced at 1:5,000 scale from 1:7,000-scale color-infrared aerial photographs of selected study sites.

185 Air Photointerpretation and Satellite Imagery Analysis Techniques for Mapping Cattail Coverage in a Northern Everglades Impoundment
Ken Rutchey and Les Vilchek

Four interacting confounding factors (i.e., water depth/color, impacts from fire, periphyton species composition, and growth morphology within a single species) are implicated as possible elements that complicated vegetation classification.

193 Integrated Multimedia Approach to the Utilization of an Everglades Vegetation Database
Shunfu Hu

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-animal interactions, hurricane damage, and post-fire vegetation succession.
