Global Positioning System is the first book to guide social scientists with little or no mapping or GPS experience through the process of collecting field data from start to finish. The book takes readers step-by-step through all the key stages of a GPS fieldwork project, covering planning, implementation, and data integration. For each phase, the authors supply clear and concise explanations of relevant technical topics, such as accuracy issues, the selection of appropriate GPS equipment, and the use of coordinate systems. Separate text boxes highlight important practical considerations and give sample solutions for real GPS data collection issues. Model checklists for project planning and equipment can be used as a basis for readers' own projects. Researchers and students from fields as diverse as sociology, anthropology, geography, and public health will find this an invaluable resource.Spencer, John is the author of 'Global Positioning System A Field Guide for the Social Sciences', published 2003 under ISBN 9781405101851 and ISBN 1405101857.
