"Dr. Van Sickle has made yet another contribution to the field with this update on his popular book, Basic GIS Coordinates. As demonstrated with this book, he has a unique capability for explaining the complications and nuances of coordinate systems in an understandable manner. This book should have a prominent place in the library of the many people having a role in using coordinate systems for their work and everyday life." Lynn E. Johnson, University of Colorado, Denver, USA
"No GIS educator or practitioner should be without Basic GIS Coordinates. Jan Van Sickle explains some of our fields most challenging, yet fundamental, concepts with unsurpassed clarity. His combination of long professional experience, deep study, and clear expression prepare him uniquely to create this invaluable reference work. Meanwhile, the impending replacement of North Americas primary horizontal and vertical datums add a new sense of urgency to this welcome 3rd edition." David DiBiase, Esri, Redlands, California, USA
"This book address the issue of accurately representing our 3D planet in a 2D forum. The author covers the traditional ways of representing location in X,Y, and Z space and the challenges with these techniques; and provides a comprehensive view of coordinate systems, datums, and other details associated with location description." Kumar Navulur, PhD, Frederick, Colorado, USA
"The Basic GIS Coordinates by Dr. Van Sickle has become a favorite book for many of my students. I would recommend this book to everybody who wants to learn the foundations of the coordinate systems, datums, and basic geodetic principals. There are several other books on this subject, but Basic GIS Coordinates stands above all of them for one simple reason: the genuine way of describing complex scientific principals in plain English without extensive heavy mathematics. I strongly recommend." Apostol Panayotov, University of Col
