« The quadtree and octree are hierarchical data structures used to represent spatial data. This book shows how these spatial data structures can be applied in computer graphics, image processing, geographic information systems (GIS), and other domains. It illustrates the representation of region data, in particular, both in two dimensions with quadtrees and in three dimensions with octrees. The advantage of hierarchical data structures is their ability to focus on interesting subsets of the data, resulting in more efficient representation and faster execution. Thus, they are particularly convenient for performing set operations. Even where other data structures might perform as efficiently, hierarchical data structures are often preferred for their conceptual clarity and ease of implementation. The author begins with a general introduction to spatial data structures. He continues with explanations of how to convert between quadtrees and other representations, as well as applications such as geometric property computation, image transformations, ray tracing, and image compression. The approach is algorithmic. Each chapter after the introduction contains at least one detailed algorithm, written in pseudo code, to illustrate an application. Each critical step in these algorithms is described with a liberal use of examples. Each chapter also includes a large number of exercices, with solutions provided for many. The book focuses on implementation techniques and the uses of spatial data structures. Readers desiring a more complete introduction to these representations, including fundamental concepts, basic techniques, and a broad range of possible uses, should refer to another book by the same author, The design and analysis of spatial data structures. The introductory material in Applications of spatial data structures makes the book self-contained. Each book contains an extensive bibliography, and the books are cross-referenced. »--Quatrième de couverture.

Although there are many advanced and specialized texts and handbooks on algorithms, until now there was no book that focused exclusively on the wide variety of data structures that have been reported in the literature. The Handbook of Data Structures and Applications responds to the needs of students, professionals, and researchers who need a mainstream reference on data structures by providing a comprehensive survey of data structures of various types. Divided into seven parts, the text begins with a review of introductory material, followed by a discussion of well-known classes of data structures, Priority Queues, Dictionary Structures, and Multidimensional structures. The editors next analyze miscellaneous data structures, which are well-known structures that elude easy classification. The book then addresses mechanisms and tools that were developed to facilitate the use of data structures in real programs. It concludes with an examination of the applications of data structures. The Handbook is invaluable in suggesting new ideas for research in data structures, and for revealing application contexts in which they can be deployed. Practitioners devising algorithms will gain insight into organizing data, allowing them to solve algorithmic problems more efficiently.

· This book is an updated version of a well-received book previously published in Chinese by Science Press of China (the first edition in 2006 and the second in 2013). It offers a systematic and practical overview of spatial data mining, which combines computer science and geo-spatial information science, allowing each field to profit from the knowledge and techniques of the other. To address the spatiotemporal specialties of spatial data, the authors introduce the key concepts and algorithms of the data field, cloud model, mining view, and Deren Li methods. The data field method captures the interactions between spatial objects by diffusing the data contribution from a universe of samples to a universe of population, thereby bridging the gap between the data model and the recognition model. The cloud model is a qualitative method that utilizes quantitative numerical characters to bridge the gap between pure data and linguistic concepts. The mining view method discriminates the different requirements by using scale, hierarchy, and granularity in order to uncover the anisotropy of spatial data mining. The Deren Li method performs data preprocessing to prepare it for further knowledge discovery by selecting a weight for iteration in order to clean the observed spatial data as much as possible. In addition to the essential algorithms and techniques, the book provides application examples of spatial data mining in geographic information science and remote sensing. The practical projects include spatiotemporal video data mining for protecting public security, serial image mining on nighttime lights for assessing the severity of the Syrian Crisis, and the applications in the government project ‘the Belt and Road Initiatives’.

This book covers fundamental aspects of spatial data modelling specifically on the aspect of three-dimensional (3D) modelling and structuring. Realisation of "true" 3D GIS spatial system needs a lot of effort, and the process is taking place in various research centres and universities in some countries. The development of spatial data modelling for 3D objects is the focus of this book.

Spatial statistics has been widely used in many environmental studies. This book is a collection of recent studies on applying spatial statistics in subjects such as demography, transportation, precision agriculture and ecology. Different subjects require different aspects of spatial statistics. In addition to quantitative statements from statistics and tests, visualization in forms of maps, drawings, and images are provided to illustrate the relationship between data and locations. This book will be valuable to researchers who are interested in applying statistics to spatial data, as well as graduate students who know statistics and want to explore how it can be applied to spatial data. With the processing part being simplified to several mouse clicks by commercial software, one should pay more attention to justification of using spatial statistics, as well as interpretation and assessment of the results. GIScience proves to be a useful tool in visualization of spatial data, and such useful technology should be utilized, as part, for the interpretation and assessment of the results.
