Athens, Greece
Greece’s Attica region, with Athens near the center. In the water, different shades of blue indicate different types of sea surface, influenced by currents and waves. The image was acquired in ‘interferometric wide swath’ mode and with a dual polarisation. Photo: ESA
Napa Valley, California
Following the biggest earthquake in 25 years to strike California’s Napa Valley, Sentinel-1a was able to generate an interferogram showing how the ground moved during the quake by processing two images. This capability marks the beginning of a new era in earthquake mapping from space. Source: ESA/PPO.labs/Norut/COMET-SEOM Insarap

This image of the Aral Sea, located on the border between Kazakhstan and Uzbekistan in Central Asia was created by combining three radar scans from Sentinel-1a. Different colours represent changes between the acquisitions. Source: Copernicus Data/ESA
The Project, which is part of the ESA's Copernicus program, was created for land and sea monitoring, mapping of natural disasters, and sea ice observation. Here we look at some of the amazing imagery those first 12 months have produced, including incredible cityscapes, meandering glaciers, and the terrain following a magnitude 6.0 earthquake striking California's Napa Valley in August, 2014. Pictured here, the density of Tokyo's urban landscape is shown by bright radar reflections, the polar opposite of the Minami-Bōsō Quasi-National Park pictured to the southwest of Tokyo Bay.
