Features: This book is a teaching or professional reference for non-geodesy professionals, introducing geodetic coordinate systems and geodetic datums. Chapter 1, Introduction, covers the research content of geodesy, a brief history, and the concept and development of geodetic datums. Chapter 2 discusses commonly used geodetic coordinate systems and their conversions. Chapter 3 introduces the establishment and development of China's national geodetic control network. Chapter 4 explains some mathematical relationships and calculation methods of reference ellipsoids as mathematical benchmarks for geodesy. Chapter 5 covers Gauss projection and Mercator projection as the mathematical foundation for map drawing. Chapter 6, based on foreign literature, provides a comprehensive and detailed introduction to the widely used WGS84 World Geodetic System, including its definition, basic constants, geopotential model, and conversions with other local geodetic datums. Chapter 7 briefly introduces other common geodetic coordinate systems and datums. Chapters 8 and 9,, introduce the World Magnetic Model WMM2000 and the marine environment of China's coastal waters, along with basic knowledge of marine surveying and marine remote sensing. This book can serve as a reference for engineering technicians in navigation, maritime navigation, aerospace, seismology, petroleum, water conservancy, agriculture, forestry, GIS, and remote sensing, working in the fields of surveying, navigation, and positioning services.
