This is an account of a classic turf battle in Washington, D.C. and one that kept flaring up for decades. The fact that it has not been resolved whether military or civilian organizations can conduct federal scientific investigations better, or whether the military should do anything more than defense, lends a timelessness to this story.

As in previous editions, the symbols used on paper nautical charts produced by NOAA and the NGA and digital raster representations of those charts, such as NOAA Raster Nautical Chart (NOAA RNC's), are presented in lettered sections organized in categories, such as Landmarks, Depths, and Lights.

A number of trends and forces are converging to require change in the National Oceanic and Atmospheric Administration's (NOAA) nautical charting mission. The most salient among these are changes in customer requirements, with a growing demand for customized and digital nautical information products; a changing customer base that encompasses uses of nautical charts in conjunction with coastal management, regulation, and development activities; and advances in technologies both for acquiring survey data and for structuring, displaying, analyzing, and disseminating nautical information. This volume assesses the needs of users of nautical information; reviews existing and emerging technologies; and examines major issues associated with information acquisition, chart preparation, and dissemination. The book addresses user requirements for improved nautical chart products, as well as technical and programmatic issues relating to the need for and provision of nautical information.

For more than thirty years, the History of Cartography Project has charted the course for scholarship on cartography, bringing together research from a variety of disciplines on the creation, dissemination, and use of maps. Volume 6, Cartography in the Twentieth Century, continues this tradition with a groundbreaking survey of the century just ended and a new full-color, encyclopedic format. The twentieth century is a pivotal period in map history. The transition from paper to digital formats led to previously unimaginable dynamic and interactive maps. Geographic information systems radically altered cartographic institutions and reduced the skill required to create maps. Satellite positioning and mobile communications revolutionized wayfinding. Mapping evolved as an important tool for coping with complexity, organizing knowledge, and influencing public opinion in all parts of the globe and at all levels of society. Volume 6 covers these changes comprehensively, while thoroughly demonstrating the far-reaching effects of maps on science, technology, and society—and vice versa. The lavishly produced volume includes more than five hundred articles accompanied by more than a thousand images. Hundreds of expert contributors provide both original research, often based on their own participation in the developments they describe, and interpretations of larger trends in cartography. Designed for use by both scholars and the general public, this definitive volume is a reference work of first resort for all who study and love maps.
