Geographical Data Acquisition / Edition 1

This book is dedicated to the theory and methodology of geographical d ata acquisition, providing comprehensive coverage ranging from the def inition of geo-referencing systems, transformation between these syste ms to the acquisition of geographical data using different methods. Em phasis is placed on conceptual aspects, and the book is written in a s emi-technical style to enhance its readability. After reading this boo k, readers should have a rather good understanding of the nature of sp atial data, the accuracy of spatial data, and the theory behind variou s data acquisition methodologies. This volume is a textbook for GIS st udents in disciplines such as geography, environmental science, urban and town planning, natural resource management, computing and geomatic s (surveying and mapping). Furthermore it is an essential reading for both GIS scientists and practitioners who need some background informa tion on the technical aspects of geographical data acquisition.
