Over the years since its first appearance, Datums and Map Projections has become a key book for many students and professionals around the world. Its theme - a practical guide to coordinate reference systems - is as important now as when it was first published, probably more so when we consider the ever growing use of satellite navigation systems and the introduction of web mapping services such as Google Earth. While retaining the benefits of the first edition - clear presentation assuming no prior knowledge, a problem-solving approach, practical examples and the combination of GPS-derived data from other sources - the rewritten and expanded second edition offers very much more:

This new edition, now with a co-author, will maintain the book's reputation as the ideal guide to the subject for years to come.

Introduction; Coordinates and reference systems; Map projections; Tranformations; Global navigation satellite systems; Case studies - Transformation of GPS data into a local coordinate reference system; Creation of a three-parameter geocentric transformation from an official national transformation; Designing a map projection; Calculations using map grid coordinates; Creating overlays in Google Earth; Appendices - Terminology; Computations with spherical coordinates; Basic geometry of the ellipsoid; The Molodensky equations; Determination of transformation parameters by least squares; References

This remains a vital text for students and practitioners in all areas of geomatics - surveying, remote sensing, GIS, GPS - and much more. Its accessible nature also makes it suitable for anyone with an interest in the subject and its applications.

'...the 2nd edition is a practical guide for GIS, surveying and remote sensing professionals. It also serves as an excellent introduction to coorinate systems and map projections for students and professionals working outside the surveying and cartographic disciplines, who need to understand and interpret the maps presented to them for decision-making purposes... ...comprehensive and readable text of value to GIS and surveying professionals, as well as students of geography...'GEO:connexion International

'... substantial: informative, comprehensive, useful, nicely presented, even enjoyable, and a prospective text-book on the parts of geodesy which are most relevant to the surveyor. ... ... the quantitative and qualitative coverage of this book is such that it turns out to be, ...a candidate for a text-book on the crucial aspects of geodesy needed by surveyors!' AZIMUTH

'...is expertly crafted, to appeal to both the geodesist and the cartographer. The explanations and derivations unfold steadily and logically, whilst the use of case studies shows the applications of the concepts in an effective manner. It acts both as a book to dip into to confirm points and operations, and an extensive textbook which can be read and absorbed from beginning to end. It is highly recommended.' SoC Bulletin


Reviews of the first edition:

'What a wonderful little book! ... first class ... worthy of recommendation to students and professional practitioners alike.' The Photogrammetric Record

'The book is a welcome addition to the Whittles stable of geomatics texts ... I'll certainly be recommending it to my students!' SoC Bulletin

'... would suggest it becomes compulsory reading before anyone attempts to use maps to display positionally referenced data. It will also be of value to all surveying students ...' Surveying World

'... the author should be congratulated on providing a clear explanation of the terminology, relationships, transformations and computations involved when combining data from different sources. ... well detailed case studies ... ideal for anyone trying to come to grips with the complexities of datums and map projections.' Cartography

‘…is one of those books you will refer to over and over again during your career…this completely revised and updated second edition would suit students and practising professionals equally…professionals of geoscience, geology, engineering, geodesy or cartography would clearly benefit from the material presented in this text…The book is concise, logically presented, with clear and highly resolved colour images. Qualitatively the book serves as an excellent guide for all geoscience professionals'. PESA News
