strength-of-figure

A system used to measure the accuracy of shapes. Small angles produce a large strength of figure value (undesirable); large angles produce a low strength of figure value (desirable).

Using the Project Settings dialog, you can specify the maximum strength-of-figure for a photogrammetry point that, if exceeded, causes a warning flag to display with the point. The value range is 0.1 to 99. The default is 2.63, which corresponds to a two-line intersection of 30 degrees.
