The Profile Meter Program (PMP) automates acquisition of soil surface, elevation data from pin meter photographs and reduces operator error.* This PC-based program uses simple image analysis techniques to determine pin tip locations from pin meter photos scanned with a digitizing scanner. The PMP simplifies digitization, reduces by up to one-fourth the time required to obtain elevation data from a pin meter photo, and eliminates many operator-induced errors prevalent in hand digitizing techniques. This program is cost effective when compared to other automated or semi-automated methods of obtaining surface elevation data. KEYWORDS. Soil profile meter. Image analysis. Wind erosion.
