ec.europa.eu_In an article published in Nature on 7 December 2016, JRC scientists describe how, in collaboration with Google, they have quantified changes in global surface waters and created interactive maps which highlight the changes in the Earth’s surface water over the past 32 years.

The data show that the impacts of climate on where and when surface water occurs can be measured, and that the presence of surface water can be substantially altered by human activities.

Based on over three million satellite scenes (1 823 Terabytes of data) collected between 1984 and 2015, the Global Surface Water Explorer was produced using 10 000 computers running in parallel. The individual images were transformed into a set of global maps with a 30-metre resolution, which enable users to scroll back in time to measure the changes in the location and persistence of surface water globally, by region, or for a specific area. The maps are available for all users, free of charge. Tiếp tục đọc “Bản đồ hoá hiện trạng nước mặt toàn cầu: Mapping long-term global surface water occurrence” →
