Features: DEM is the core data in geographic databases and the foundation for terrain analysis, widely used in fields such as surveying, remote sensing, resources, environment, urban planning, agriculture and forestry, disaster management, hydropower engineering, and military. This book is written by the author based on scientific research and teaching practice in the fundamental theories and methods of DEM. It systematically introduces the basic concepts of DEM, data organization and management of DEM, DEM construction and processing, visualization expression of DEM, and accuracy analysis of DEM, as well as other key theories and technologies. From four aspects—slope terrain factor extraction, terrain feature element extraction, terrain statistical analysis, and geoscientific model analysis—the book elaborates on the fundamental theories and methods of DEM digital terrain analysis. It also showcases the research achievements of DEM in the study of slope spectra on the Loess Plateau, the characteristics of surface gullies, the analysis of mountain climate features, and the spatial differentiation of vegetation.
As a specialized textbook, this book can serve as teaching material for undergraduate and graduate students in fields such as geography, geology, oceanography, meteorology, surveying, and environmental protection. It is also suitable for reading and reference by professionals in related disciplines.
