Updated weekly, ESA’s Observing the Earth archive consists of thousands of photographs that date back to 2005. These Earth Observation images capture wide-angle snapshots of various landscapes with a precision that could only be matched by an “army of ground-level observers.” With incredible accuracy, these satellite images can capture environmental changes to the landscape in real-time, from a creeping blanket of air pollution to the catastrophic damage wrought by an earthquake.
This long-term monitoring provides an objective assessment of human activity’s global impact and even the effects of climate change. Although satellite acquisitions are often depicted as static images, they are actually comprised of layers of workable digital data. Over time, the images collected can reveal the unfolding scale of environmental destruction and weather mapping and help contribute to environmental activism and identification of at-risk areas to natural disasters.
