206 value. The authors stress the a m o u n t of rewriting that has gone into t h e second edition, but m a n y e x a m p l e s and m u c h of the illustrative material is relatively old. (Pre-1976 is nearly a full generation ago in this t e c h n o l o g y ) and better more recent examples certainly exist. S o m e of the illustrations, figures and tables, are excellent and add a great deal to the book.

D e m a n d for a general i n t r o d u c t o r y text: on r e m o t e sensing of the e n v i r o n m e n t may well warrant a third edition, and if so, I hope the authors will be ready with a collection of additional and re~ p l a c e m e n t illustrations that will further increase the impact of the text.

B.L. Deekshatulu and Y.S. Rajah (Editors) : R e m o t e Sensing. Indian A c a d e m y o f Sciences, Bangalore, 1984, 304 pp., US $30. The Indian A c a d e m y of Sciences presents in this volume a review o f activities related to r e m o t e sensing in various national research and application centers and agencies. More t h a n thirty authors o f the Indian research centers and two at US institutions present in n i n e t e e n c o n t r i b u t i o n s the state o f the art, research results and projects with relevance to, or directly tied to, national projects. The topics covered are reaching f r o m basic research and t e c h n o l o g y problems, via agricultural, land use, geologic and resources survey mapping, image processing and pattern recognition, microwave

r e m o t e sensing, m e t e o r o l o g i c and hydrologic applications, to overviews of the Indian r e m o t e sensing program, in particular the Indian R e m o t e Sensing Satellite (IRS) and international issues in r e m o t e sensing. Several c o n t r i b u t i o n s are specifically addressing topics o f national interest, however, the m a j o r i t y of the papers is of general interest for a wide c o m m u n i t y . The b o o k can serve not only as an i n v e n t o r y o f the Indian activities, but also as a t e x t b o o k o n techniques and applications o f r e m o t e sensing. E. Schanda, Berne, Switzerland
