Fundamentals of Geodesy Pt II – Classical Horizontal Data

Abstract/Description

Accurate descriptions of horizontal positions are defined with respect to a reference surface or datum.  This course will describe the general architecture of a horizontal/geometric datum and how that process has evolved since the early nineteenth century, including the evolution of the agencies now represented by the National Geodetic Survey (NGS), the process of triangulation and space-based positioning.

Learning Objectives

• What are the fundamental elements of horizontal datums
• History of horizontal datums in the United States
• Procedures involved in geodetic triangulation
• Advances in geodetic measurements
• Evolution of space-based positioning
• Datum differences and transformation tools
