Aerial imagery

"All of the images in Overview were created by stitching together numerous satellite photographs from DigitalGlobe’s 15-year time-lapse image library, which contains some of the world’s highest quality satellite imagery."

"Grant named the project after the “Overview Effect,” a sensation of profound shift in perspective that astronauts experience when given the opportunity to look down and view the Earth as a whole. His hope is that by giving viewers a chance to engage with these far-flung perspectives, we can not only share in that unique, rare sensation, but also gain a new understanding of our place on the planet."
