The black outline shows the approximate coastline of the lake in 1960. The combined measurement helps enable global observations of the land every two to three days at 30 meter spatial resolution. Neumayer Glacier is on the east coast of South Georgia, an island some 1,200 miles (2,000 kilometers) east of South America’s southern tip. The Aral Sea was the fourth largest lake in the world until the 1960s, when the Soviet Union diverted water from the rivers that fed the lake so cotton and other crops could be grown in the arid plains of Kazakhstan, Uzbekistan and Turkmenistan. The river meanders and straightens, braids and unbraids as the amount of water fluctuates and changing sediment deposits divert the flow. The HLS data provides consistent surface reflectance data from the Operational Land Imager (OLI) aboard the joint NASA/USGS Landsat 8 satellite and the Multi-Spectral Instrument (MSI) aboard the European Union’s Copernicus Sentinel-2A and Sentinel-2B satellites. The size and shape of Bangladesh’s Padma River (upper left to lower right) have been changing for decades. Researchers pre-trained NASA’s Harmonized Landsat Sentinel-2 (HLS-2) data. Rather than train a foundation model on words, IBM Research taught a model to understand satellite images. The photograph was captured by the Cassini spacecraft from a distance of almost 576,000 miles (927,000 km). Cassini, accompanied by Huygens Probe, landed on the surface of Saturn’s largest moon Titan in 2005. A prolonged period of unusually warm weather and drought caused the decline. Delhi, India NASA image shows a large portion of Saturn and its ring. The difference is especially apparent in the adjacent marshes, lagoons, and streams of the river delta. Previously, users had to train a new model for each task, which required extensive data curation and compute. These images show the drop in water level in a section of the Paraná River, near Rosario, Argentina, over the span of one year. Foundation models have revolutionized natural language processing (NLP) by allowing developers to train one model on raw text, and with extra training, customize the model for other NLP tasks. Here are seven transformations that NASA has captured.As part of a Space Act Agreement with NASA, IBM set out just four months ago to build the first-ever foundation model for analyzing geospatial data. But these, too, are the result of weather patterns that have morphed over decades. To address the problem of limited change detection accuracy in existing single-level difference networks, this study proposes the Multi-level Difference Network (MDNet) for automatic change detection of ground targets from very high-resolution (VHR) remote sensing. Of course, there are also sudden, dramatic events like flash floods that overwhelm a region overnight. Automatic change detection based on remote sensing is playing an increasingly important role in the national economy construction. From one month to the next, an environmental change might seem slight, but when you zoom out to the level of years and decades, the combined shifts paint a devastating portrait. (Jökull is Icelandic for glacier.) A 1901 geological map estimated that Okjökull spanned about 15 square miles (38 square kilometers).

By the time ice shelves disappear, ocean waves creep onto main streets, and forests shrivel, the forces of climate change have been at work for decades.įortunately, NASA is tracking these environmental changes with satellites so that the public knows the full scale of transformations taking place. This animated GIF shows the Chinese Change lander (large white dot in the center of the second image) and Yutu rover (smaller white dot below the lander). These images show the latter stages of the decline of Okjökull, a melting glacier atop Ok volcano in west-central Iceland. Rising waters destroyed tens of thousands of homes and sent millions of people to refugee camps. Climate change rarely transforms an environment overnight. The monsoon of summer 2017 caused catastrophic flooding in northern India, Nepal and Bangladesh.
