Eartha

Eartha is a 3-dimensional scale model of our earth with mountains and landforms in full 3D, that rotates and revolves, simulating the earth’s real movements. Eartha was given the title of "World's Largest Revolving/Rotating Globe" by the editors of the Guinness Book of World Records in 1999, and still holds that record today. It measures 41.5 ft in diameter. Unveiled July 23, 1998 Eartha took two years to build and represents earth as it is seen from space. It rotates and revolves on a specially designed and built mechanized, cantilever arm.
The official measurements of Eartha were made for Guinness by several independent and licensed surveyors who found the Globe to measure 41 feet, one and one-half inches, slightly less than the rounded figure of 42 feet that was projected by DeLorme staff members. Still, 41' 1.5" was more than enough to surpass the former record-holder, the Globe of Peace in Apeccio, Pesaro, Italy (which is 33 feet in diameter and does not revolve or rotate).
An Engineering Accomplishment
Every aspect of Eartha was developed using computer technology. It was designed by David DeLorme, CEO. and constructed by DeLorme staff members. “The building of Eartha was a tremendous challenge for all of us," says DeLorme. "It will help us make even better maps and will help others envision how we on earth are all connected.”
