DC-01 - Survey theory and electro-optical methods

Learning Objectives: 
  • Apply coordinate geometry to calculate positions in a coordinate system grid based on control point locations and measured angles and distances
  • Given the elevation of one control point, calculate the elevation of a second point by differential (spirit or direct) leveling
  • Given the elevation of one control point, calculate the elevation of a second point by trigonometric (indirect) leveling
  • Describe the differences between differential and trigonometric leveling
  • Explain how electronic distance measurement instruments work
  • Define the concepts ellipsoidal (or geodetic) height, geoidal height, and orthometric elevation
  • Illustrate the relationship between the concepts of ellipsoidal (or geodetic) height, geoidal height, and orthometric elevation
