International Standard Book Number: 0-309-08478-4 Library of Congress Control Number: 2002110505 Front cover: Left—a GeoCover-Ortho image of Mount Kilimanjaro originally obtained at 30 × 30 m spatial resolution. It has a positional accuracy of better than 50 m (root mean square error). Landsat TM bands 7,4,2 (mid-infrared, near-infrared, and green) are displayed (courtesy of Earth Satellite Corpora- tion). Each color or shade is unique and depends on the vegetation type, health, and growth stage. The bright greens are dense vegetation. The purples and pinks are sparse to no vegetation. The bottom third center of the image along Mount Kilimanjaro’s lower slopes contains areas of clear cuts (in pinks) sur- rounded by uncut verdant forest (bright greens). The top of the mountain is snow-covered (blue) and the white areas are clouds. Upper Right—artist’s rendition of the Shuttle Radar Topography Mission 60-m (200-ft) mast being deployed from the space shuttle Endeavor (courtesy NASA Jet Propulsion Labora- tory). Radar images are collected from the end of the mast and from the shuttle payload bay. Lower Right—paper maps used in decision support in Namibia (courtesy of Jo Tagg, Namibia Nature Founda- tion).

Printed in the United States of America The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished schol- ars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Acad- emy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering pro- grams aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Acad- emy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org COMMITTEE ON THE GEOGRAPHIC FOUNDATION FOR AGENDA 21 JOHN R.
