Professor James Cheshire talks about maps from his book "Atlas of the invisible". In the 1980s, the National Oceanic and Atmospheric Administration began digitizing more than three centuries' worth of observations from ocean buoys and ship logs, including Maury's maps. The records capture the evolution of ever faster shipping routes that now criss-cross the globe.
