Planetary Mapping describes the history and process of mapping planets and satellites beyond the Earth. Mapping planetary bodies is a unique process much different from ordinary terrestrial cartography. Although many kinds of imaging systems have been launched into interplanetary space, nearly all of them were designed for purposes other than map-making. Thus, special mapping techniques described in this book had to be invented to make use of images from space. Furthermore, planets and satellites are difficult to depict in maps. For instance, unlike on Earth, on planetary bodies there are no shorelines, rivers, roads or political boundaries to guide the map-maker. The book begins with an introduction to the differences between terrestrial and planetary mapping and continues with a general discussion of the history of planetary mapping. The fundamentals of cartographic techniques are described in detail in the next chapter. This is followed by sections on planetary nomenclature, geodetic considerations, and topographic and geologic mapping.

This book gives an account of geological aspects of windblown material. Aeolian processes play an important role in modifying the surface of the Earth, and they are also active on Mars. Additionally, they are thought to occur on Venus and possibly Titan as well. The authors describe the following aspects: wind as a geological process, the aeolian environment, physics of particle motion, aeolian abrasion and erosion; aeolian sand deposits and bedforms, interaction of wind and topography and windblown dust. A particular strength of the book is that it deals with aeolian processes in a planetary context, rather than as a purely terrestrial phenomenon. In so doing, the authors ably demonstrate how we can gain better understanding of the Earth through comparative planetology. This paperback reissue will enable the book to be used as a text for advanced students in planetary science. Special terms are defined when they are first used. There is a glossary and an exhaustive bibliography.
