The Geographic Projection is the southern hemisphere of a globe; this being a representation of Earth suggests that the Pikmin planet is Earth. The item is found in the same place as the Yellow Onion in the first game. This heavy treasure is found in the Awakening Wood, and requires Purple Pikmin to be picked up, due to the fact that its weight is 101 and thus 100 weaker Pikmin cannot lift it. It is slightly buried and located near the longest constructible bridge in the area, behind a poison gate near the Hole of Beasts. A Creeping Chrysanthemum is nearby.
Retrieving the treasure unlocks the Survey Chart, part of the Exploration Kit, allowing the Pikmin captains to progress to the Perplexing Pool. The Spherical Atlas is also a globe half, this time a northern hemisphere, and it too unlocks an area to land in (Awakening Wood).
