Terrain Evaluation: An Introductory Handbook to the History, Principles, and Methods of Practical Terrain Assessment - Tapa blanda

(The aim of this book is to meet the need, expressed by T.G.Miller (1967) and others, for a brief, popular, and inexpensive introduction to terrain evaluation. From a start in the years following the World War II, many individuals and organizations caused a wide expansion of the field. Some workers published summaries of their own and related contributions (eg Christian and Stewart 1968, Beckett and Webster 1969, Webster and Beckett 1970), and the proceedings of an important symposium, edited by G.A.Stewart, assembled summaries of the advances to 1968. The first edition of the present work, published in 1973, sought to provide a simple collation and summary of these and related principles, methods and examples for the benefit of those professionally involved in the use and management of land, students, and general readers. Since that time public awareness of the need for environmental conservation and planning has continually grown. This has contributed to extensive developments in most aspects of the subject, especially in classifications of the earth's surface, remote sensing and data processing technologies, and geographical information systems. The preparation of a second edition gives the opportunity to incorporate these changes, to extend the range of topics covered, notably in including terrain processes and the place of vegetation, and to include a wider range of land user interests)
