Earth globe based on official NASA satellite imagery. It combines two separate datasets: one showing Earth's best features: its mountains, valleys and other major geological structures shown in their natural colors. The other depicting the fascinating topography hidden beneath the oceans and seas.
Labels are limited to major geographical features to preserve the globe's natural beauty and underlying details of the map. In addition it will give one a sense of what Earth looks like from outer space.
We eliminated political boundaries and minimized labels to focus on our home planet as a planetary body, featuring stunning geographical features both on land and under the waves.

Data for the land masses comes from a mosaic of thousands of images, known
as the Blue Marble, acquired by MODIS instruments (short for Moderate
Resolution Imaging Spectroradiometer) aboard NASA's Terra and Aqua
satellites. The MODIS instruments make their observations in 36 spectral
bands at a resolution of 500 meters (0.3 mile) per pixel and with consistent
solar illumination. Our globe depicts Earth as it appears in September — the
transition from summer to autumn in the Northern Hemisphere and the onset of
spring in the Southern Hemisphere.
For the 71% of the globe not involving land, we turned to bathymetry from the British Oceanographic Data Centre. BODC scientists amass these data using "acoustic radar" — by generating sound waves at the surface that travel through the water, bounce of the seafloor, and return upward to waiting detectors. These acoustic echoes also reveal details about the size and shape of seamounts (underwater mountains) and seafloor roughness. Darker blue shadings indicate greater depths.
No sea ice is shown, which makes it easy to distinguish water from land. Nor are there clouds — though at any given moment they hide about 70% of our planet.
The globe has a diameter of 12 inches, which corresponds to a scale of 1:42,000,000.
