Interesting article for those interested in electronic navigation. Of course the problem is not just the source of the electronic chart but those who interpolate!
www.stripes.com/news/poor-leadership-planning-led-to-uss-guardian-hitting-reef-near-philippines-report-finds-1.226746 'USS Guardian, a U.S. Navy minesweeper en route to Indonesia, ran aground on the Tubattaha Reef on Jan. 17 2013, and it looks like a digital chart used for navigation has been a significant contributing factor to the mishap.
Noteworthy, according to Navy Times: ?as of Jan. 18 2013, Navy ships have been directed to ?operate with caution? when using similar electronic charts and compare the map data with paper charts, which are considered accurate.?
While the investigation will determine all the contributing factor to the incident, the preliminary analysis indicates that the reef was misplace as a result ?from incorrect geographic rectification of satellite imagery used to built? the type of Digital Nautical Charts (DNC) used by the minesweeper and most USN ships.
Hence, not an epic fail as that of Apple Maps, but possibly more dangerous.
All the source data for nautical charts will be reviewed.
In the meanwhile old paper charts will guide U.S. warships through the world?s troubled waters.'
