Precision vs. correctness (accuracy)
Precision
Precision is the random error of a measurement.
Example: In photogrammetry with drones, we can reliably take measurements and volumes from a precise model.
Accuracy is the systematic error of a measurement.
Example: In photogrammetry with drones, we can reliably extract dimensions, volumes and coordinates from a correct model.
Precision and accuracy together result in accuracy.
