Planimere

Planimere is a touch-first three-dimensional land-survey instrument. Take the cyan tracing lens, settle it onto one of seven numbered contour origins, then follow the entire engraved boundary without lifting. A working polar planimeter accumulates the signed line integral of the actual spring-lagged lens path; the measuring wheel preserves the inherited total and phase across four surveys.
