A group headed off into the jungle to begin the necessary measurement and planning work, equipped with only basic instrumentation, machetes to cut a pathway through the undergrowth, rope to measure distances in units of ten meters, a spirit level, and surveying poles made from two dried branches.
一行人揮著柴刀劈出路徑，用繩索充當十米軟尺來丈量距離，帶著一座水平儀與兩支用枯枝削製成的測量棒，往叢林裡一鑽便開始測量和規劃工作。
