NASA Earth Observatory just released a gigapixel image of the Landsat Data Continuity Mission (LDCM) that you can zoom into and explore the image using Gigapan viewer. You can see the incredible image in detail once you dive in!
NASA captured the world's largest panoramic photo at 6,000 miles long and 120 miles wide using a satellite orbiting 438 miles above the Earth. The swath is made up of 56 still images taken during the satellite's final orbit and stretches from northern Russia down to South Africa.
Information about the Long Swathmosaic: On April 12, 2013, the Landsat Data Continuity Mission (LDCM) reached its final orbit, 705 kilometers (438 miles) above Earth. One week later, the satellite's natural-color imager scanned a swath of land 185-kilometers wide and 9,000 kilometers long (120 by 6,000 miles)--an unusual, unbroken distance considering 70 percent of Earth is covered with water. That flight path afforded us the chance to assemble 56 still images into a seamless, flyover view of what LDCM saw on April 19, 2013. Stretching from northern Russia to South Africa, the full mosaic from the Operational Land Imager can be browsed here: http://www.gigapan.com/gigapans/129988
