LORAN Still Worth The Trouble?
On Nov 28, 9:27*am, Michael Porter
I am sure the NOAA vector charts are in large part made by contractors' digitizing of paper charts, probably mylar originals). I've seen or heard several references to the basis for all vector charts being work done by the Russians during the cold war in case they ever needed to invade. It's a good story and I suspect that it's true since the timing and investment make it more plausible that Garmin et. al. purchased and updated work done over a period of several years than that they came up with it from scratch. I'd like to know for sure though. Have a great passage to Bermuda. -- Roger Long |
