What is the combined factor for the traverse of Problems 20.27 and 20.28?
Problem 20.27:
The horizontal ground lengths of a three-sided closed-polygon traverse were measured in feet as follows: AB = 501.92, BC = 336.03, and CA = 317.88 ft. If the average orthometric height of the area is 4156.08 ft and the average geoid separation is -23.05 m, calculate ellipsoid lengths of the lines suitable for use in computing SPCS83 coordinates. (Use 6,371,000 m for an average radius for the Earth.)
Problem 20.28:
Assuming a scale factor for the traverse of Problem 20.27 to be 0.99996294, calculate grid lengths for the traverse lines.
Problem 20.27:
