Pa 109 Assignment - Elevation of Inaccessible Points Field Note Reduction and Calculations The following field measurements were taken to determine the elevation of the top of a building. Reduce the field notes and calculate the required elevation. Use engineering paper for the calculations, and illustrate your work with appropriate sketches Note: Using the data provided, you will be able to calculate two values for the building elevation.
