Description

Capable of acquiring large volumes of data through sensors deployed in air, land, and sea, and making this information readily available in a continuous time frame, the science of geographical information system (GIS) is rapidly evolving. This popular information system is emerging as a platform for scientific visualization, simulation, and computation of spatio-temporal data. New computing techniques are being researched and implemented to match the increasing capability of modern-day computing platforms and easy availability of spatio-temporal data. This has led to the need for the design, analysis, development, and optimization of new algorithms for extracting spatio-temporal patterns from a large volume of spatial data.

Computing in Geographic Information Systems considers the computational aspects, and helps students understand the mathematical principles of GIS. It provides a deeper understanding of the algorithms and mathematical methods inherent in the process of designing and developing GIS functions. It examines the associated scientific computations along with the applications of computational geometry, differential geometry, and affine geometry in processing spatial data. It also covers the mathematical aspects of geodesy, cartography, map projection, spatial interpolation, spatial statistics, and coordinate transformation. The book discusses the principles of bathymetry and generation of electronic navigation charts.

The book consists of 12 chapters. Chapters one through four delve into the modeling and preprocessing of spatial data and prepares the spatial data as input to the GIS system. Chapters five through eight describe the various techniques of computing the spatial data using different geometric and statically techniques. Chapters nine through eleven define the technique for image registration computation and measurements of spatial objects and phenomenon.

  • Examines cartographic modeling and map projection
  • Covers the mathematical aspects of different map projections
  • Explores some of the spatial analysis techniques and applications of GIS
  • Introduces the bathymetric principles and systems generated using bathymetric charts
  • Explains concepts of differential geometry, affine geometry, and computational geometry
  • Discusses popular analysis and measurement methods used in GIS

This text outlines the key concepts encompassing GIS and spatio-temporal information, and is intended for students, researchers, and professionals engaged in analysis, visualization, and estimation of spatio-temporal events.

Reviews

"This book addresses mathematics and computational methods that are not usually covered by common GIS books. Unlike other books that only teach people how to apply GIS and use GIS software, this book describes the underlying principles and mathematical equations. Engineers who develop innovative tools for GIS users would find this book useful."

––Shipeng Sun, University of Minnesota, Minneapolis, USA

"There are only few books that deal with mathematical aspects of GIS. This book will help to fill this gap. The most valuable contribution of this book is the fact that it effectively pervades mathematical equations and formulas to discuss geospatial concepts and principles. GIS topics are amply covered, and are approached in a way that will help students of GIS to gain greater knowledge of the computational aspects of spatial data collection, transformation, manipulation, analysis and application."
