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
