365 pp.

“As I mentioned in class, this book has great figures and tables, but somehow I haven't found the actual text useful for anything but giving me ideas of possible methods to use and references to papers. The book itself hasn't been useful in helping me figure out HOW to implement any of the methods.”

Bailey, Trevor C. and Anthony C. Gatrell. Interactive Spatial Data Analysis. 1995.Pearson Education Limited, Essex, England. ISBN 0-582-24493-5 (paperback). 413pp. Includes a diskette.

“I recommend this one. It goes into the statistical theory but minimally and it gives a very good presentation of different methods that existed as of 1995.”

Isaaks, Edward H., and R. Mohan Srivastava. An Introduction to Applied Geostatistics. Oxford Univ. Press. ISBN 0-19-505013-4 (paperback). 561 pp.

“I also recommend this one for geostatistics, e.g. variograms, correlograms,covariance. It is a great, easy to read introduction to terminology and concepts.”
