Remotely-sensed images of the Earth's surface provide information about the geographical distribution of natural and cultural features, as well as a record of changes in environmental conditions over time. Computer processing takes place after these digital images have been collected by aircraft and satellite-borne sensors. The processing techniques will depend on the physical properties of the images and the applications for which they will be used.This fully revised and updated edition deals with the mechanics of processing remotely-sensed images. Presented in an accessible manner. This book covers a wide range of image processing and pattern recognition techniques. A number of examples are included on the accompanying website to illustrate the practical use of specific techniques.This book continues to be distinct from other remote sensing texts on the market as it provides a good grounding in the interpretation of digital imagery with the material on image processing remaining a key element throughout. The focus of the Third Edition will be retained with emphasis on the more applied aspects of the subject. There will now be a completely new chapter on GIS and Remote sensing which will consider issues surrounding the integration of Remote Sensing and GIS and the applications of environmental GIS with key examples provided to reinforce student understanding. Fully revised and updated throughout the latest developments in the field will also be included where necessary.
