The wetlands are distinguished from other lands of the Mid-Willamette Valley by excessive soil moisture. The wetlands, as defined for this study, consist of 20 soil series (in 22 soil mapping units) which are classified by the Soil Conservation Service as having excessive wetness as the major factor limiting their...
Equal value gray scales are frequently employed by cartographers to choose gray tone area
symbols. Several researchers have tried to quantify perceived gray tone as a function of percent area inked or
reflectance but results have varied. The influence of pattern and texture on gray tone perception is considered
