BBC - Future - The last unmapped places on Earth
Have we mapped the whole planet? As Rachel Nuwer discovers, there are mysterious, poorly charted places everywhere, but not for the reasons you might think.
Scientists have produced what they say is the most accurate space view yet of global ocean currents and the speed at which they move
In 1504, an anonymous mapmaker – most likely an Italian – carved a meticulous depiction of the known world into two halves of conjoined ostrich eggs. The grapefruit-sized globe included recent breaking discoveries of mysterious distant lands, including Japan, Brazil and the Arabic peninsula. But blanks remained. In a patch of ocean near Southeast Asia, that long-forgotten mapmaker carefully etched the Latin phrase Hic Sunt Dracones – “Here are the dragons.”
Today it is safe to say there are no unknown territories with dragons. However, it’s not quite true to say that every corner of the planet is charted. We may seem to have a map for everywhere, but that doesn’t mean they are complete, accurate or even trustworthy.
