Computer Processing of Remotely Sensed Images has built up a strong following in the UK. The third edition will introduce several new elements into the text and CD, which are designed to maintain and gain adoptions in the UK and to specifically target the US market where sales to date have been relatively low. The 3/e will include the following changes: Current chapter 3 (Digital computer and image processing) will be removed as the majority of the material is now dated. Core topics will be merged with other chapters. A new Image Summary appendix providing an overview of now commonly used images (e.g. LANDSAT, SPOT) Current chapter 2 (Remote sensing platforms and sensors) will omit specific details of different satellite/sensor systems to make room for more generic coverage of optical, microwave and thermal remote sensing instruments. This will act as a basic introductory chapter to the technical aspects of remote sensing systems and their applications. Appendices A, B and C that provide details on the MIPS software and installation procedures will be removed from the text and placed on the CD-ROM. The revisions outlined above will ensure that the 3/e is more applied and relevant to todays student, without becoming too unwieldy in terms of size.
