"Eartha is the world's largest rotating and revolving globe, located within the former headquarters of the DeLorme mapping corporation in Yarmouth, Maine. Garmin purchased the company and the building in 2016. The globe weighs approximately 5,600 pounds (2,500 kg), and has a diameter of over 41 feet (12.5 m).

"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.

"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."

"Eartha was originally designed to be 42 feet (12.8 m) in diameter. In 1999, surveyors hired by the Guinness Book of World Records measured the globe at 41 feet 1.5 inches (12.53 m). The previous record holder is the Globe of Peace located in Apecchio, Pesaro, Italy." (Wikipedia)

"Most of you must be having a globe at home. This spherical model of the Earth that comes in various sizes, was invented in 1492 by German cartographer Martin Behaim in collaboration with German painter Georg Glockendon. Many believe, it is this globe model that inspired Spanish explorer Christopher Columbus to set sail and explore the entire world," the HT School says.

"Eartha is a 5600 pounds globe. It is the world’s largest rotating and revolving globe and is located in the earlier headquarters of DeLorme, a mapping corporation in the Yarmouth region of Maine, USA. Currently, it is owned by Garmin, an American multinational tech company. Eartha has a whopping diameter of 41 feet and was built on a scale of 1:1000,000, in which an inch is equal to 16 miles. Just like most globes, Eartha too is mounted at a 23.5 degree angle, imitating Earth’s own axial tilt. This means, the equator is diagonal to the floor. 

"What makes it special is that, it can both rotate and revolve. For that, Eartha uses a cantilever with two motors. In fact, it exhibits a day’s rotation and revolution, once every 18 minutes. The motors also allow the globe to fully rotate itself in less than a minute, if customized. In addition, the globe is built around a spherical structure called Omni Span that is comprised of 6000 units of aluminium tubes. They are in turn covered by 792 plastic panels that gives it 8 degrees of latitude and longitude."

"The World's Largest Rotating and Revolving Globe is nicknamed "Eartha", and it can be found at DeLorme's headquarters in Yarmouth, Maine, a 15-minute drive north of Portland. This Big Thing To See has a diameter of 41 feet and weighs about 2.8 tons! Eartha is built to an exact 1-to-1-million scale, meaning that one millimeter on its surface corresponds to one kilometer on Earth's surface," the VroomVroomVroom.com says.

"This Big Globe is motorized, and one combined rotation and revolution occurs every 18 minutes. Eartha was designed and constructed entirely by DeLorme employees -- quite an achievement! You can see Eartha by visiting DeLorme, or by just driving past the building in your rental car. It's easy to spot the Big Globe from US Route 1, and the glass-walled atrium where it's mounted is lit up at night!

"If you decide to get a close look, DeLorme's Giant Globe atrium is open for public visits during regular business hours. Of course, there's also a gift shop that sells geography products and Eartha souvenirs. The atrium also features 2 balconies, so you can see the northern hemisphere more easily."

"Eartha, housed in a three-story glass gallery at the former DeLorme Headquarters (they were acquired by Garmin in 2016), is the world’s largest rotating/revolving globe. Eartha was designed by CEO David DeLorme and successfully completed two years later in 1998. It won its Guinness Book record the next year, outshining the previous record holders in both Italy and Massachusetts," the Atlas Obscura says

"Just over 41 feet in diameter, the enormous structure was designed as a scale model. At the scale of 1:1,000,000, or approximately one inch equaling 16 miles, California is a mere three and a half feet tall on Eartha.

"Eartha is tilted at 23.5 degrees, just like Earth, and is rotated about that axis by an electric motor. Simultaneously, a second motor swivels the entire tilted, rotating globe around the attachment point to the floor, together giving a approximation of Earth’s own simultaneous day-night and annual cycles. It takes about 18 minutes for Eartha to complete a cycle."

"Eartha is the world's largest revolving globe, a creation of DeLorme, an innovative map-making company that was headquartered in Yarmouth, Maine, from the time it was founded in 1976. DeLorme was purchased by Garmin in 2016, but Eartha remains open to the public," the TripSavvy.com says.

"Designed by former CEO David DeLorme and constructed by DeLorme staff, Eartha is a technological marvel and a wondrously detailed, three-story, three-dimensional representation of our planet and its movements.

"Like our Earth, Eartha tilts at 23.5 degrees, and she rotates on an "axis," a specially designed cantilever arm. It took more than a year for DeLorme cartographers to compile the data used to create this giant globe, which occupies Garmin's three-story lobby and is open free to the public weekdays year-round."

"The world's largest rotating globe, nicknamed "Eartha", is located at the headquarters of DeLorme, a business that provides mapping products, which is in Yarmouth, Maine, the United States, about 15 minutes north of Portland. The globe is enormous — 41 feet in diameter and weighs 2,500 kg, so big that you need to take the stairs to the second or third floor to see the northern hemisphere. In 1999 the Guinness Book of World Records confirmed it was the largest globe to be ever made, beating the previous title holder, the Globe of Peace, located in Pesaro, Italy, by more than 9 feet. The globe is housed inside a three-story glass atrium which is beautifully illuminated at night and readily visible from U.S. Route 1," the Amusing Planet says.

"Eartha was unveiled in 1998 and took two years to complete. It was built at a scale of 1:1 million, meaning that one millimeter on its surface corresponds to one kilometer on Earth's surface. That allowed the builders to put great deal of details such as road networks and urban areas, as well as relief and ocean depth info. The database used to generate the surface images was approximately 140 gigabytes. That was a big thing back in 1998. Google Maps wasn’t invented then.

"The globe is built on a skeleton of over 6000 pieces of aluminum tubing which is covered by a skin of 792 map panels. As with most globes, its mounted at a 23.5 degree angle, the same axial tilt as the Earth itself. The equator is thus diagonal to the floor. It uses a cantilever mount with two motors, that slowly rotates the globe completing one rotation in about 18 minutes, but it can be sped up to fully rotate the globe in as little as one minute or slowed down to an hour."

"Geography boffins shouldn't miss a visit to the Garmin company – its lofty office atrium is home to a giant rotating globe named Eartha," the Lonely Planet says.



"Eartha has a diameter of 41.5ft and has been acknowledged by Guinness World Records as the world's largest revolving and rotating globe. The detail on it is impressive, as is the opportunity for visitors to stop by. Note that even if the lobby is closed, you can see the Earth(a) spinning through the windows."

"Eartha is the world's largest rotating and revolving globe, located within the headquarters of the DeLorme mapping corporation in Yarmouth, Maine," the Road Trippers says.

"The globe weighs approximately 5,600 pounds, and has a diameter of over 41 feet."

"In Yarmouth you'll find the headquarters of the DeLorme Corporation, which was founded in 1976 by David DeLorme, who was frustrated by outdated maps of Maine and thought he could do better. In 1997, after 20 years of worldwide success and expansion, DeLorme moved into a gleaming new headquarters. The centerpiece of the new facility? Eartha, the largest rotating globe in the world," the Only In Your State says.

"DeLorme has no desire to hide this colossal sphere away from the public. It's housed in a glass-walled atrium so drivers on nearby US 1 can easily see it. Photos can only do Eartha so much justice. It measures more than 41 feet in diameter, but don't take DeLorme's word for it -- the gargantuan size has been certified by the Guinness Book of World Records.

"Visitors can get up close and personal with Eartha. You'll have the opportunity to observe impressive features such as the globe's Omni-Span truss structure, which supports it with more than 6,000 pieces of aluminum tubing. The globe was constructed to a perfect 1:1,000,000 scale, where one inch represents 16 miles. It rotates and revolves to simulate one full day every 18 minutes."
