Denmark has a rich history of nautical charting that dates back to the seventeenth century, and many of its navigational products for Greenland were created in the 1960s. The information on those charts was good and sufficient for traditional navigation, but when GPS started to gain prominence in shipping in the 1990s and early 2000s, hydrographic offices around the world had to start producing Electronic Navigational Charts (ENCs). But Denmark’s existing data—especially farther north, around Greenland—didn’t line up with GPS points or new high-quality multibeam sonar readings. So the hydrographic office at the Danish Geodata Agency (known by its Danish acronym GST) needed to take a different approach.
