Datums And Map Projections For Remote Sensing Gis And Surveying Pdf

Datums and Map Projections for Remote Sensing, GIS, and Surveying

New methods of acquiring spatial data and the advent of geographic information systems (GIS) for handling and manipulating data mean that we no longer must rely on paper maps from a single source, but can acquire, combine, and customize spatial data as needed. To ensure quality results, however, one must fully understand the diverse coordinate frameworks upon which the data are based. Datums and Map Projections provides clear, accessible explanations of the terminology, relationships, transformations, and computations involved in combining data from different sources. The first half of the book focuses on datums, exploring different coordinate systems and datums, including two- and three-dimensional representations of Earth coordinates and vertical datums. After an overview of the global positioning system (GPS), the author introduces the fundamentals of map projections and examines the different types. He then presents models and procedures for transforming directly between data sets. The final chapter presents case studies of projects that illustrate the types of problems often encountered in practice. Newcomers to the field will welcome this treatment that, instead of detailed mathematics, uses lucid explanations and numerous examples to unravel the complexities of the subject. For more experienced readers, the book is a valuable reference that answers specific questions and imparts a better understanding of transformation operations and principles. Features

The SAGE Handbook of Online Research Methods

This handbook is the first to provide comprehensive, up-to-the-minute coverage of contemporary and developing Internet and online social research methods, spanning both quantitative and qualitative research applications. The editors have brought together leading names in the field of online research to give a thoroughly up to date, practical coverage, richly illustrated with examples. The chapters cover both methodological and procedural themes, offering readers a sophisticated treatment of the practice and uses of Internet and online research that is grounded in the principles of research methodology. Beginning with an examination of the significance of the Internet as a research medium, the book goes on to cover research design, data capture, online surveys, virtual ethnography, and the internet as an archival resource, and concludes by looking at potential directions for the future of Internet and online research. The SAGE Handbook of Internet and Online Research Methods will be welcomed by anyone interested in the contemporary practice of computer-mediated research and scholarship. Postgraduates, researchers and methodologists from disciplines across the social sciences will find this an invaluable source of reference.
