Gigapans are large, high-resolution dgital images created by digitally stitching hundreds of small photographs together to form a complete image. The process involves using a robotic camera platform which measures, aligns, and moves a camera in precisely defined steps, while panning and zooming on all areas of the subject.
Your camera has millions of pixels, Gigapans have BILLIONS. At Keystone, we use Gigapans to study rock outcrops in extreme detail. Use the controls below to take a closer look.
Cerro Chopo: An extinct volcano in Costa Rica that is being quarried for road construction material. It is literally being cut in half, so you are looking at the internal structure, which shows layers of successive eruptions. Note the reverse graded beds that indicate changes in the intensity during each eruption.
Arenal: An active stratovolcano in Costa Rica that erupted explosively in 1968. Since that time, it has had repeated small eruptions and numerous lava flows.
Miravalles caldera deposits: Explosive deposits from a massive eruption over 1 million years ago in Costa Rica. These ash and pumice deposits have been redeposited here by water. Look for cross bedding, ripples, and other structures associated with moving water. Some layers are conglomerates with rounded pumices.
