I can fly a survey and pull clean data most of the time. But this job needed accuracy down to the centimeter, and when I checked the numbers back at the desk, one section was just off enough to matter. I have to go back and refly it, and I still don't know what I missed.
More people experience this than they realize.
You capture data well until the accuracy demands get tight enough to trip you.
