Geomorphometry is the science of quantitative terrain characterization and analysis, and has traditionally focused on the investigation of terrestrial and planetary landscapes. However, applications of marine geomorphometry have now moved beyond the simple adoption of techniques developed for terrestrial studies, driven by the rise in the acquisition of high-resolution seafloor data and by the availability of user-friendly spatial analytical tools. Considering that the seafloor represents 71% of the surface of our planet, this is an important step towards understanding the Earth in its entirety. This volume is the first one dedicated to marine applications of geomorphometry. It showcases studies addressing the five steps of geomorphometry: sampling a surface (e.g., the seafloor), generating a Digital Terrain Model (DTM) from samples, preprocessing the DTM for subsequent analyses (e.g., correcting for errors and artifacts), deriving terrain attributes and/or extracting terrain features from the DTM, and using and explaining those terrain attributes and features in a given context. Throughout these studies, authors address a range of challenges and issues associated with applying geomorphometric techniques to the complex marine environment, including issues related to spatial scale, data quality, and linking seafloor topography with physical, geological, biological, and ecological processes. As marine geomorphometry becomes increasingly recognized as a sub-discipline of geomorphometry, this volume brings together a collection of research articles that reflect the types of studies that are helping to chart the course for the future of marine geomorphometry.

From the reviews: "Bishop and Schroder (both, Univ. of Nebraska at Omaha) have brought together an impressive group of practitioners in the relatively new application of geographic information science to mountain geomorphology. In doing so, they have produced valuable, first, overall coverage of a high-tech approach to mountain, three-dimensional research. More than 40 contributing authors discuss a wide range of related aspects.... The book is well bound and well produced; each chapter provides an extensive source of references. The numerous line drawings are clearly reproduced, although the mediocre quality of photographic reproduction limits the value of air photographs and satellite images. As is characteristic of many edited collections, there is some variation in chapter quality. Some of the writing is so dense that it requires minute concentration--one chapter, for instance, has 14 pages of references from a total of 43 pages. Nevertheless, this is a vital compendium for a rapidly expanding field of research. Summing Up: Recommended. Upper-division undergraduates through professionals." (J. D. Ives, Choice, March 2005)

This study addresses a two-class problem in automatic terrain classification. the basic-level terrain feature selected for initial delineation is a mount - an aggregation of elevated features including hills, mountains, and ranges. All remaining areas are classified collectively as non-mount. A method was developed to partition digital elevation models (DEMs) into mount and non- mount areas automatically. Then, the developed method is compared to those results obtained by a manual classification of synthetic stereo images produced from the same digital elevation data. The results of this work suggest that it may be possible to replicate the manual identification of mounts in certain physiographic regions. However, the general utility of the mount/nonmount classification approach appears to be limited by the nature of the regional terrain and by the quality of available digital data.

"Geomorphometry is the science of quantitative land-surface analysis and be part of an interdisciplinary approach to understanding natural hazards. It spans the research range from simple land observation to mathematical models of land surfaces. In this geomorphometric context, modelling is used to generate computerized representations of parts of the Earth's surface, based on digital elevation/surface models (DEM/DSM) and additional data and observations. New and improved algorithms for modelling both physico-geographical and geological processes and landforms how they change in space and time are presented in this volume: Data acquisition methods for acquiring high resolution elevation data, at local to regional scales. Novel methods for processing computation of extensive sets of elevation data and the improvement of existing methods. Application paths which present, how different data and methods give a new prompt to the various aspects of monitoring natural processes and modelling of natural hazards"--Back cover.

Geomorphometry is widely used to solve various multiscale geoscientific problems. For the successful application of geomorphometric methods, a researcher should know the basic mathematical concepts of geomorphometry and be aware of the system of morphometric variables, as well as understand their physical, mathematical and geographical meanings. This paper reviews the basic mathematical concepts of general geomorphometry. First, we discuss the notion of the topographic surface and its limitations. Second, we present definitions, formulae and meanings for four main groups of morphometric variables, such as local, non-local, two-field specific and combined topographic attributes, and we review the following 29 fundamental morphometric variables: slope, aspect, northwardness, eastwardness, plan curvature, horizontal curvature, vertical curvature, difference curvature, horizontal excess curvature, vertical excess curvature, accumulation curvature, ring curvature, minimal curvature, maximal curvature, mean curvature, Gaussian curvature, unsphericity curvature, rotor, Laplacian, shape index, curvedness, horizontal curvature deflection, vertical curvature deflection, catchment area, dispersive area, reflectance, insolation, topographic index and stream power index. For illustrations, we use a digital elevation model (DEM) of Mount Ararat, extracted from the Shuttle Radar Topography Mission (SRTM) 1-arc-second DEM. The DEM was treated by a spectral analytical method. Finally, we briefly discuss the main paradox of general geomorphometry associated with the smoothness of the topographic surface and the non-smoothness of the real topography; application of morphometric variables; statistical aspects of geomorphometric modelling, including relationships between morphometric variables and roughness indices; and some pending problems of general geomorphometry (i.e. analysis of inner surfaces of caves, analytical description of non-local attributes and structural lines, as well as modelling on a triaxial ellipsoid). The paper can be used as a reference guide on general geomorphometry.

Mountain Geomorphology - Integrating Earth Systems presents the papers of the 32nd Annual Binghamton Geomorphology Symposium, held in 2001 in advance of the United Nations-designated '2002 International Year of Mountains'. The three co-editors have collectively worked in mountain environments for over 70 years, and brought together internationally recognized experts in mountain geomorphology from 7 nations presenting research on mountain processes from around the world, including the USA, Canada, China, Europe, and South America. The volume utilizes Earth Systems as a unifying and organizing theme, examining the interactions of the four Earth "spheres" (Lithosphere, Biosphere, Atmosphere, and Hydrosphere) in the context of geomorphic processes in mountain environments. The volume is also a "Festschrift" in honor of Professor John D. "Jack" Vitek, long-time editor of Geomorphology and an outstanding mentor to each of the three co-editors. Papers presented in the volume represent cutting-edge examinations of mountain landforms, geomorphic processes in mountains, and the application of advanced remote sensing and Geographic Information Science technologies for the study of mountain geomorphology. The book should be of interest to all geomorphologists, and to physical geographers and geologists interested in mountain environments. Mountain Geomorphology - Integrating Earth Systems is the only book of its kind, and stands as a testament to the importance of mountains as locations for studying the interaction of geomorphic processes within an Earth Systems perspective.

This book presents approaches to landscape modelling not only from geography but also from various related disciplines, especially from applied mathematics, computer science, and geophysics. New methods of terrain representation, analysis and classification are presented as well as short- and long-term process models. The intention of the book is not to give a complete overview of these broad and complex topics, but to stimulate interdisciplinary cooperation and to encourage scientists to consider the ideas of related disciplines.
