Reply to "Laser distance meter for cal course layout?"

I've received a couple cal course applications where the measurement was by Total Station. The only thing in the documentation that really convinced me that the measurement was accurate was the "professional surveyor" by the measurer's name.

I think the only way we could accept this type of measurement is if the measurer has proven ahead of time that he is capable of accurately measuring a course with this technique. That's why I suggested in another thread that we allow EDMs to be used for the second measurement of a cal course. Once a measurer has shown 2 or 3 times that his EDM measurement of cal courses is very similar to his taped measurement of cal courses, he could use only his EDM in the future.

Actually, a better practice would be to allow EDMs for the first measurement, with taping required for the second. Best for them to test the accuracy of their method without knowing what the right answer is.
