The study and application of spatial information systems have been developed primarily from the use of computers in the geosciences. These systems have the principle functions of capturing, storing, representing, manipulating, and displaying data in 2-D and 3-D worlds. This book approaches its subject from the perspectives of informatics and geography, presenting methods of conceptual modeling developed in computer science that provide valuable aids for resolving spatial problems. This book is an essential textbook for both students and practitioners. It is indispensable for academic geographers, computer scientists, and the GIS professional. Serves as the first comprehensive textbook on the field of Spatial Information Systems (also known as Geographic Information Systems) Contains extensive illustrations Presents numerous detailed examples

The applications of geomatics technology in its broader context have resulted in significant progress in the field of earth science. This book provides brief coverage on some trends in geomatics technology as it relates to earth scientists. The development in geomatics, whether GIS, remote sensing, GPS or photogrammetry, can be seen from trends in the applications of Big Data, Smart City, Internet of Things (IoT), the use of augmented reality and utilization of unmanned aerial vehicles (UAVs) and in the impact of machine learning and AI on geomatics.

The definitive guide to bringing accuracy to measurement, updated and supplemented Adjustment Computations is the classic textbook for spatial information analysis and adjustment computations, providing clear, easy-to-understand instruction backed by real-world practicality. From the basic terms and fundamentals of errors to specific adjustment computations and spatial information analysis, this book covers the methodologies and tools that bring accuracy to surveying, GNSS, GIS, and other spatial technologies. Broad in scope yet rich in detail, the discussion avoids overly-complex theory in favor of practical techniques for students and professionals. This new sixth edition has been updated to align with the latest developments in this rapidly expanding field, and includes new video lessons and updated problems, including worked problems in STATS, MATRIX, ADJUST, and MathCAD. All measurement produces some amount of error; whether from human mistakes, instrumentation inaccuracy, or environmental features, these errors must be accounted and adjusted for when accuracy is critical. This book describes how errors are identified, analyzed, measured, and corrected, with a focus on least squares adjustment—the most rigorous methodology available. Apply industry-standard methodologies to error analysis and adjustment Translate your skills to the real-world with instruction focused on the practical Master the fundamentals as well as specific computations and analysis Strengthen your understanding of critical topics on the Fundamentals in Surveying Licensing Exam As spatial technologies expand in both use and capability, so does our need for professionals who understand how to check and adjust for errors in spatial data. Conceptual knowledge is one thing, but practical skills are what counts when accuracy is at stake; Adjustment Computations provides the real-world training you need to identify, analyze, and correct for potentially crucial errors.

The first edition of The Surveying Handbook, although a ground breaker, was widely accepted. However, surveying is a dynamic profession with each new development just one step ahead of the next, and updating became critical. In addition, the editors received constructive criticism about the first edition that needed to be addressed. So, while the objective of The Handbook remains intact, the logical evolution of the profession, along with the need to recognize constructive criticism, led to the second edition. chapters have been added on water boundaries, boundary law, and geodetic positioning New satellites. The chapter on land data systems was rewritten to provide a dramatic updating of information, thus broadening the coverage of The Handbook. The same may be said for the state plane coordinate chapter. The material on public lands and construction surveying was reorganized as well. Appendices were added to tabulate some information that was buried in the earlier edition in several places. Numerous other changes were incorporated to help the handbook retain its profession-wide scope, one step beyond the scope of an upper-division college textbook. Along with the most sophisticated techniques and equipment, the reader can find information on techniques once popular and still important. Four new authors are welcomed to the list of contributors: Grenville Barnes, R. B. Buckner, Donald A. Wilson, and Charles D. Ghilani.
