What correction must be made to a measured slope distance prior to calculating state plane coordinates?
  1. Reduce measured slope distance to a horizontal distance at a known elevation.
  2. Correct the horizontal distance to a geodetic distance.
  3. Correct the geodetic distance to a grid distance.
  4. All of the above
Explanation
Answer: D - All of the corrections listed must be made to measured slope distances prior to calculating state plane coordinates. The resultant grid distance is used in state plane coordinate calculations.
