The mapping methods in reconnaissance surveys are somewhat different from those used in detailed surveys. ... Any original soil survey in which only a part of the soil boundaries are actually seen by the field scientist is a reconnaissance survey, in contrast to a detailed survey in which boundaries are sketched from observations of their occurrence on the ground. Thus, reconnaissance surveys may be only a little less detailed than the standard detailed soil survey. 4, record 2, English, - reconnaissance%20survey
