Today travellers by land, sea and air take accurate navigation for granted but it was not always thus. The author, a highly experienced sailor, sets out to record the development of navigational techniques from the earliest time, five millenniums ago. As explorers started to venture offshore into the unknown they had to rely on the sun and stars for direction. From this pioneers turned to mathematics, astrolobes, sextants and increasing accurate clocks to measure latitude and later longitude. More recently major breakthroughs with electronic navigation, GPS and other satellite systems have revolutionised travel. Focusing primarily but not exclusively on marine navigation, the author weaves a fascinating course through the successes and failures of mankind's quest to explore his world. The result is a thoroughly entertaining and informative work which has no rival.

This edited volume charts the history of celestial navigation over the course of five centuries. Written by a group of historians and scientists, it analyzes how competing navigation systems, technologies, and institutions emerged and developed, with a focus on the major players in the US and the UK. The history covers the founding of the Royal Observatory; the first printing of a Nautical Almanac; the founding of the US and UK Nautical Almanac Offices; the creation of international standards for reference systems and astronomical constants; and the impact of 20th century technology on the field, among other topics. Additionally, the volume analyzes the present role and status of celestial navigation, particularly with respect to modern radio and satellite navigation systems. With its diverse authorship and nontechnical language, this book will appeal to any reader interested in the history of science, technology, astronomy, and navigation over the ages.

Publisher Fact Sheet Bagur examines water transportation & the natural & socioeconomic factors that affected it in Northwest Louisiana, East Texas, & the Red River.

This new edition includes a discussion of theories about traditional methods of navigation developed during recent decades, the story of the renaissance of star navigation throughout the Pacific, and material about navigation systems in Indonesia, Siberia, and the Indian Ocean.

Finding one’s way with a map is a relatively recent phenomenon. In premodern times, maps were used, if at all, mainly for planning journeys in advance, not for guiding travelers on the road. With the exception of navigational sea charts, the use of maps by travelers only became common in the modern era; indeed, in the last two hundred years, maps have become the most ubiquitous and familiar genre of modern cartography. Examining the historical relationship between travelers, navigation, and maps, Cartographies of Travel and Navigation considers the cartographic response to the new modalities of modern travel brought about by technological and institutional developments in the twentieth century. Highlighting the ways in which the travelers, operators, and planners of modern transportation systems value maps as both navigation tools and as representatives of a radical new mobility, this collection brings the cartography of travel—by road, sea, rail, and air—to the forefront, placing maps at the center of the history of travel and movement. Richly and colorfully illustrated, Cartographies of Travel and Navigation ably fills the void in historical literature on transportation mapping.

Offers a theory that explains the impact of emotions on historical change.
