What horizontal length would have to be observed to lay off/ Civil Engineering
In computing state plane coordinates for a project area whose mean orthometric height is 305 m, an average scale factor of 0.99992381 was used. The average geoidal separation for the area is
-23.83 m. The given distances between points in this project area were computed from SPCS83 state plane coordinates. What horizontal length would have to be observed to lay off these lines on the ground? (Use 6,371,000 m for an average radius for the Earth.)
(a)* 2834.79 ft
(b) 230.204 m
(c) 823.208 ft
