An enthralling biography of the man who created the first real map of the world and changed civilization Born at the dawn of the age of discovery, Gerhard Mercator lived in an era of formidable intellectual and scientific advances. At the center of these developments were the cartographers who painstakingly pieced together the evidence to create ever more accurate pictures of the planet. Mercator was the greatest of all of them-a poor farm boy who attended one of Europe's top universities, was persecuted and imprisoned by the Inquisition, but survived to coin the term "atlas" and to produce the so-called projection for which he is known. Devoutly religious, yet gripped by Aristotelian science, Mercator struggled to reconcile the two, a conflict mirrored by the growing clash in Europe between humanism and the Church. Mercator solved the dimensional riddle that had vexed cosmographers for so long: How could the three-dimensional globe be converted into a two-dimensional map while retaining true compass bearings? The projection revolutionized navigation and has become the most common worldview. Nicholas Crane-a fellow geographer-has combined a keen eye for historical detail with a gift for vivid storytelling to produce a masterful biography of the man who mapped the planet.

In Rhumb Lines and Map Wars, Mark Monmonier offers an insightful, richly illustrated account of the controversies surrounding Flemish cartographer Gerard Mercator's legacy. He takes us back to 1569, when Mercator announced a clever method of portraying the earth on a flat surface, creating the first projection to take into account the earth's roundness. As Monmonier shows, mariners benefited most from Mercator's projection, which allowed for easy navigation of the high seas with rhumb lines—clear-cut routes with a constant compass bearing—for true direction. But the projection's popularity among nineteenth-century sailors led to its overuse—often in inappropriate, non-navigational ways—for wall maps, world atlases, and geopolitical propaganda. Because it distorts the proportionate size of countries, the Mercator map was criticized for inflating Europe and North America in a promotion of colonialism. In 1974, German historian Arno Peters proffered his own map, on which countries were ostensibly drawn in true proportion to one another. In the ensuing "map wars" of the 1970s and 1980s, these dueling projections vied for public support—with varying degrees of success. Widely acclaimed for his accessible, intelligent books on maps and mapping, Monmonier here examines the uses and limitations of one of cartography's most significant innovations. With informed skepticism, he offers insightful interpretations of why well-intentioned clerics and development advocates rallied around the Peters projection, which flagrantly distorted the shape of Third World nations; why journalists covering the controversy ignored alternative world maps and other key issues; and how a few postmodern writers defended the Peters worldview with a self-serving overstatement of the power of maps. Rhumb Lines and Map Wars is vintage Monmonier: historically rich, beautifully written, and fully engaged with the issues of our time.

Space Image Processing covers the design and coding of PC software for processing and manipulating imagery obtained by satellites and other spacecraft. Although the contents relate to several scientific and technological fields, it serves as a programming book, providing readers with essential technical information for developing PC applications. The material focuses on images of the planet and other celestial bodies obtained by orbiting and non-orbiting spacecraft. This book is not about raster graphics in general, but about raster graphics processing as it applies to space imagery. Three parts divide the text: Science - background at an introductory level - scientific principles underlying space imagery and its processing - topics related to space and remote sensing Technology - topics related to space imagery - geodesy, cartography, image data formats, image processing Programming - code examples for DOS and Windows programming on the PC - consideration of low-level and C++ code - routines with a tutorial and demonstrative purpose Space Image Processing includes a CD-ROM holding all the source code and programs discussed in the text. The CD contains a demo version of the TM-Lab program, a public domain Thematic Mapper scene of the Grand Canyon area, two public domain space image viewers, and sample images.
