From the reviews: "This is one of the first books trying to introduce object-oriented theory and practise especially for spatial sciences. ... The examples may be used as starting point for own implementation because they are well described ... . Thus, I would recommend it for higher level graduate and postgraduate students as well as practitioners in the field of surveying, geodesy, cartography, photogrammetry ... . For these readers it will give a deeper insight into object-oriented concepts ... . will help beginners to do the first successful steps in object-orientation." (Ralf Bill, Photogrammetrie-Fernerkundung-Geoinformation, Issue 6, 2004) "This is a well-presented book, with a clear structure and writing style, which is easy to follow. ... the author's objective has been achieved, as the book takes the reader smoothly from basic concepts behind object-oriented methodology to the building of models with objects and patterns, concluding with applied examples. ... the book is suitable for undergraduate students of Spatial Sciences and Engineering disciplines ... . would also be suitable for teaching units within distance-based graduate programmes in spatial sciences or engineering."
