![]() International trade, which links countries through a complex web of supply chains, is an area where timely information is especially valuable for improved analysis and decision making. Policymakers often need to know what is happening to the economy in real-time, but they frequently must settle for data that provides insights only into what happened weeks ago. ![]() Trade nowcasting with near-real-time data These new datasets have already informed trade nowcasting and marine spatial planning-see the two examples below-and will undoubtedly provide the basis for further analyses and public policies in the future.Ī global overview of the density of ship traffic, as derived from 6 years of cumulative AIS signals. So far, our analysis has resulted in new, open-access datasets providing high-frequency seaborne trade estimates and showing Global Shipping Traffic Density on a global scale. Using various machine-learning and spatial data processing techniques, we mapped out years of vessel AIS data to uncover shipping lanes and derive trade volume estimates. Recently, the International Monetary Fund (IMF) and the World Bank undertook a joint effort to harness the wealth of information generated by AIS messages and determine whether these insights can inform trade analysis, development work, and public policies. The AIS data signals broadcast a range of information including a ship’s position, speed, category, and water depth. Satellites and terrestrial stations capture the location reporting radio signals these devices routinely emit, resulting in thousands of daily observations per vessel. Can we shed more light on the oceans by capitalizing on ship movement data for economic analysis and sustainable development? Thanks to a repurposed data flow, powerful algorithms, and the commitment of international organizations to open data, the answer is yes.įor navigational safety purposes, the International Maritime Organization requires most ships to carry a device commonly known as AIS (Automatic Identification System). ![]() ![]() ![]() Despite the strategic importance of international marine trade, governments find themselves with limited or incomplete data to inform relevant policies. Every day, tens of thousands of ships cross our seas and oceans, carrying the vast majority of traded goods. Seventy percent of the Earth’s surface is covered by water. ![]()
