The book is extremely well organized and is useful to both the novice and experience operator. ESRISAT John C Davis, Geoff Bohling ...is unique in its approach to contouring and related topics....the book is extremely valuable for those interested in contouring algorithms. No other compilation provides such a complete survey of the field, nor such a consistent evaluation of the alternatives. Computers & Geosciences Vol 19 No 9 Christopher Gold There are a few books in this world that are known universally by a single word. Within the domain of those interested in the subject, David Watson's "Contouring" may become one of these, by virtue of being cited, checked, and quoted by those struggling with the problem of representing supposedly continuous surfaces defined by a few arbitrarily distributed data...brings out into the open most of the decisions necessary for developing and choosing interpolation methods for "precise" data, and will be referenced extensively over the next few years. If you are in the business of making those decisions-make sure you can say "Watson says..."! Computers and Geosciences John McManus & Harun Mat Zin ...great practical value...to the analysis of change on sea floors for which bathymetric data are available. ECSA Bulletin D.H. Douglas ...valuable, well written and well illustrated, and covering a vast range of interpolation and contouring topics...will be useful to anyone wishing to understand the underpinnings of the whole contour processing system Geomatica John C. Davies ...extremely valuable for those interested in contouring algorithms. No other compilation provides such a complete survey of the field. Computers & Geosciences
