Mathematical geography is a branch of geography that deals with the figure and motions of the earth, its seasons and tides, its measurement, and its representation on maps and charts by various methods of projection. As is for all sciences, mathematics is needed by the geographer to help coordinate those experiences which the qualitative criteria are unable to bring to a complete logical system. For it is mathematics, the technique par excellence, that implements a comprehensive order in the knowledge of some fields in geography. The book provides an analysis of spatial patterns, the mechanisms that are responsible for creating and modifying these patterns, and the interactions among spatially distinct entities. This book treats the subject of mathematical geography with a greater degree of thoroughness.
