This authoritative book offers an up-to-date introduction to the world of Geographical Information Systems. Fully revised an updated it is designed to be easy to use for students at all levels, from undergraduates to professionals retraining in GIS. The book focuses on the practical application of GIS, and considers how the technology works.
Filled with numerous exercises this practical guide provides a real hands-on approach to learning the essential concepts and techniques of landscape ecology. The knowledge gained enables students to usefully address landscape- level ecological and management issues. A variety of approaches are presented, including: group discussion, thought problems, written exercises, and modelling. Each exercise is categorised as to whether it is for individual, small group, or whole class study.
This best-selling non-technical, reader-friendly introduction to GIS makes the complexity of this rapidly growing high-tech field accessible to beginners. Clearly linking theory and practice, it uses a "learn-by-seeing" approach that features clear, simple explanations, an abundance of illustrations and photos, and generic practice labs for use with any GIS software. Comprehensive and integrated, it provides single-volume coverage of necessary topics drawn from cartography, GIS, spatial analysis, and quantitative methods. What Is a GIS? GIS's Roots in Cartography. Maps as Numbers. Getting the Map into the Computer. What Is Where? Why Is It There? Making Maps with GIS. How to Pick a GIS. GIS in Action. The Future of GIS. For anyone interested in a hands-on introduction to Geographic Information Systems.
Watershed modeling is at the heart of modern hydrology, supplying rich information that is vital to addressing resource planning, environmental, and social problems. Even in light of this important role, many books relegate the subject to a single chapter while books devoted to modeling focus only on a specific area of application. Recognizing the need for a broad, comprehensive overview of the various types of watershed models, renowned experts Singh and Frevert carefully selected several highly popular and useful models to produce this groundbreaking reference. Watershed Models comprises seven sections that encompass 24 models chosen for a variety of characteristics, such as physical bases, mathematical sophistication, comprehensiveness, broad-based applicability, and use of modern tools. After a concise introduction, the book examines the history and evolution of watershed modeling derived from the Stanford Watershed Model along with regional calibration of models. The following six sections explore large watershed, streamflow, water quality, urban watershed, agricultural watershed, and planning and management models. Each chapter contains a wealth of information on model parameters, the strengths of each model for particular purposes, and examples of applications. Offering an up-to-date review of models used worldwide, Watershed Models supplies broad, integrated knowledge necessary for solving the complex and ongoing problems involved in resource and environmental water management.
