ESRI Press, 2001. — 116 p. — ISBN10: 1589480031; ISBN13: 978-1589480032.The text begins with a discussion of geographic coordinate systems and contrasts the Earth's appearance and structure with those of neighboring planetary bodies. This discussion includes the concepts of spheres and spheroids, datums, prime meridian. The book next presents projected coordinate systems, i.e. coordinate systems that are designed for a flat surface, such as a printed map or a computer screen, and various geographic transformations. The remaining half of the book describes over sixty supported map projections, including method, linear graticules, limitations, applications, and parameters.
