'In summary, this book will be of use primarily to those with a strong remote sensing background. This covers the most recent tools and trends, and paints an overall picture of this field. In this sense this book is a good reference for RS specialists and global change researchers. It is of interest to those dealing with global scale mapping and modelling. It presents many succesful RS applications, which may stimulate methods and data resources.' Goderma,102(2001)
