1 Report Description

This report summarizes the geographic setting of a list of musym within a shapefile. It is intented to be used to compare and contrast map units, and suggest possible Low, RV, and High values for soil components.

Five number summary (min, 25th, median, 75th, max)(percentiles) and contingency table (counts)(n) Circularity is an estimate of SHAPE complexity (Hole and Campbell, 1975), computed as a ratio of mupolygon length / mupolygon circumference. The SHAPE complexity of a perfect circle would equal 1.
