Bronze Globes

In 1998, Geo-F/X was hired by Datum3D of Boston to provide all the GIS data and calculations required to produce a perfectly scaled model of the earth. The model was going to be used to drive a multi-axis milling machine that would mill a series of pie-shaped slices of the earth out of plastic. Each slice was a 22.5 degree slice of one hemisphere. So a total of 16 slices were milled. These were then assembled by a sculptor into a globe 42" in diameter. The resulting armature was used to create a mold which was in turn used to cast a bronze earth, one hemisphere at a time. The two halves were then welded together along the equator.

The resulting bronze globe was then mounted on a pedestal and is on display at the Gottesman Hall of Planet Earth in the American Museum of Natural History in New York.

The patrons were so pleased with the result that they requested a similar globe of the moon.
