G-3/5/7The Old Way of
Inventory & Monitoring• Stubby pencil on paper or cards• Acreage determined by counting squares on
graph paper– Plannimeter was a big upgrade!– At least a 75% reduction in time to determine
acreage
• Field maps drawn while bent over light table with plats or photos– Had to have stereo pairs for 3-D viewing– Also required a stereoscope…

• Mapping done using hand compass and pacing
• Measurements done by tape and clinometer• Calculations done by hand– IBM XT computers and early spreadsheets
