The living environment is one of the most important factors for human evolution and socio-economic development. But during the last decades, the continuously increasing need of new energy resources has led to rapidly growing awareness in the field of environmental protection considering to over exploitation and environmental pollution. In order to provide effective management and environmental protection, detail knowledge and quantitative characterisation of our living environment are needed for prediction in local and global scales, in time and space. Thus, environmental modelling through the use of modern GPS technology and approaches represent high priority towards this direction. This book provides leading-edge research on this field, which is demonstrated by a number of environmental case studies that, in addition to environmental modelling, include the latest research on remote sensing, GPS, and database management.
