Coordinates are integral building tools for GIS, cartography,
surveying and are vital to the many applications we use today such
as smart phones, car navigation systems and driverless cars. Basic
GIS Coordinates, Third Edition grants readers with a solid
understanding of coordinates and coordinate systems and how they
operate as well as valuable insight into what causes them to
malfunction. This practical and comprehensive guide lays out the
foundation of a coordinate system and the implications behind
building it as it elaborates on heights, two coordinate systems,
and the rectangular system.The previous editions described
horizontal and vertical datums such as the North American Datum
1983 (NAD 83) and the North American Vertical Datum 1988 (NAVD 88).
Both will be replaced in 2022 or thereabouts. The National Geodetic
Survey (NGS) plans to replace NAD83 with a new semi-dynamic
terrestrial reference frame for North America and a new vertical
datum will replace NAVD88. The foundation of the new vertical datum
will be a temporally tracked gravimetric geoid. The interim period
is intended to smooth the transition to the new paradigm and this
new edition explores the changes and provides assistance in
understanding them.
1. Written by a well-known land surveyor with extensive knowledge
in satellite navigation and ability to explain difficult concepts
to a broad audience. 2. Includes a useful set of self-assessment
exercises and explanations at the end of each chapter. 3. Takes a
practical approach to the rapid and continuous technological
progress in GNSS. 4. Provides the latest information on GNSS and
GPS. 5. Minimizes the reliance on mathematical explanations and
maximizes the use of illustrations and examples that allow the
reader to visualize and grasp the concepts.
