About the Book

Written to address the need for updated, precise, and continuous representation of our topography, this book discusses a new approach for georelated environmental analyses processes, mainly fusion, that simultaneously handles different existing topographic databases. It enables a more true-to-nature handling of digital models representing our natural environment. The book outlines in detail the developed methodology and its different algorithms and implementations, and discusses the cases of when to use it, and how, along with statistical and visual detailing. Authors investigate and analyze real case studies and applications, and list the full algorithmic structures needed in the process.
