Measurement issues in morphometry.
Measurement is the instrument of morphometry. Several recurring issues of measurement are reviewed: types of measurement scales and their statistical consequences; types of measurement errors and their relationship to measurement scales; the differences between image resolution, digitization resolution and measurement resolution; and image measurement methods. The importance of formalized measurement protocols is illustrated with an example from daily morphometric practice.
