The geographic information system pilot project on Pool 13 of the Upper Mississippi River System was initiated to evaluate system-wide application of various methods of capturing, processing and converting resource data. Classification schemes were developed for two data themes: land cover/land use (vegetation) and aquatic areas. Evaluation of 1:15,000 scale aerial photography indicated that (1) color infrared transparencies were essential for accurately mapping major vegetation classes and vegetation units less than 1 acre; (2) color infrared prints were essential for field work (delineating work areas on the photos and identifying in the field; (3) true color (Ektachrome) transparencies and prints were not useful...

This report is the first of a series of reports on the status and trends of the nation's plants, animals, and ecosystems. It represents an effort to bridge the gap between scientists and resource managers, policy makers, and the general public. Usually, scientists tend to write for scientific journals and communicate with other scientists: this report attempts to collect a great variety of scientific data and interpret it for the nonscientist while maintaining the full credibility of the data. Published by U.S. Department of the Interior, in 1995.
