A US Geological Survey Open-File Report has recently been released entitled "Evaluation of Airborne Image Data for Mapping Riparian Vegetation Within the Grand Canyon." The 65-page document explains how the study "examined various types of remote-sensing data that have been acquired during a 12-month period over a portion of the Colorado River corridor to determine the type of data and conditions for data acquisition that provide the optimum classification results for mapping riparian vegetation." Because remote sensing is still in its early stages of development, new ways to produce more effective images are continuously and feverishly being sought. This study gives researchers and professionals good insight into how remote sensing can best be utilized for riparian and hopefully other similar vegetative areas.
