==Construction== The globe was built with a scale of 1:1,000,000, on which one inch represents sixteen miles (1mm = 1km). As with most globes, it is mounted at a 23.5 degree angle, the same axial tilt as the Earth itself; thus the equator is diagonal to the floor. It uses a cantilever mount with two motors, and simulates one day's revolution and rotation every 18 minutes, though it is possible for the motors to fully rotate the globe in as little as one minute. thumb|The truss structure of the globe made visible during a panel-replacement project in 2023 The globe was completed in 1998, after two years of construction and planning, and it uses a composite database built from satellite imagery, shaded relief, colored bathymetry, and information about road networks and urban areas. The database used to generate the surface images was approximately 140 gigabytes.
