Opis

Smart phones, car navigation systems and now driverless cars are based on coordinates and coordinate systems. This book is about why coordinate systems work, and why they sometimes don't work. The previous editions are based on the North American Datum(NAD 83), the horizontal control datum for the United States, Canada, Mexico, and Central America, and the North American Vertical Datum(NAVD 88). By tracking the dynamic nature of the Earth, NGS will provide a new National Spatial Reference System that is semi-dynamic. It will replace NAVD 88 with a GNSS/geoid datum and replace NAD 83 with a geocentric GNSS-based datum. These changes will be explained in the new edition.

O autorze

Jan Van Sickle has many years of experience in GIS, GPS, surveying, mapping, and imagery. He began working with GPS in the early 1980s when he supervised control work using the Macrometer, the first commercial GPS receiver. He created and led the GIS department at Qwest Communications, Denver, Colorado, for the company’s 25,000-mile worldwide fiber optic network. He also led the team that built the GIS for natural gas gathering in the Barnett Shale. He has led nationwide seminars based on his three books: GPS for Land Surveyors, Basic GIS Coordinates, and Surveying Solved Problems. He led the team that collected, processed, and reported control positions for more than 120 cities around the world for the ortho-rectification of satellite imagery now utilized in a global web utility. He managed the creation of the worldwide T&E sites for two major earth observation satellites that are used for frequent accuracy assessments. He created an imagery-based system of deriving road centerlines that meet the stringent Advanced Driver Assistance specifications and developed a method of forest inventory to help quantify that depleted resource in Armenia. He assisted the supervision of the first GPS survey of the Grand Canyon for the photogrammetric evaluation of sandbar erosion along the Colorado River. He has performed three-dimensional mapping with terrestrial photogrammetry and LiDAR as well as Building Information Modeling for major buildings in Washington, DC. He was a member of the team of authors for the Geospatial Technology Competency Model for the Department of Labor.
