Map Projections

The book delves into the evolution of map projections used by the U.S. Geological Survey, highlighting the shift from the Polyconic projection to various conformal, equal-area, and equidistant projections for different mapping needs. It introduces innovative projections like the Space Oblique Mercator, designed for satellite mapping, and discusses the implications of mapping extraterrestrial bodies. The text emphasizes the mathematical foundations behind these projections, providing equations and insights into their history and application, all while addressing the impact of increased computerization on cartography.
