Electronic and Paper Charts
Conventional nautical charts are printed on large sheets of paper at a variety of scales. Mariners will generally carry many charts to provide sufficient detail for the areas they might need to visit. Electronic navigational charts, which use computer software and electronic databases to provide navigation information, can augment or in some cases replace paper charts, though many mariners carry paper charts as a backup in case the electronic charting system fails.

Famous quotes containing the words electronic, paper and/or charts:
“The war was won on both sides: by the Vietnamese on the ground, by the Americans in the electronic mental space. And if the one side won an ideological and political victory, the other made Apocalypse Now and that has gone right around the world.”
—Jean Baudrillard (b. 1929)
“It is hard to believe that England is so near as from your letters it appears; and that this identical piece of paper has lately come all the way from there hither, begrimed with the English dust which made you hesitate to use it; from England, which is only historical fairyland to me, to America, which I have put my spade into, and about which there is no doubt.”
—Henry David Thoreau (1817–1862)
“There’s one basic rule you should remember about development charts that will save you countless hours of worry.... The fact that a child passes through a particular developmental stage is always more important than the age of that child when he or she does it. In the long run, it really doesn’t matter whether you learn to walk at ten months or fifteen months—as long as you learn how to walk.”
—Lawrence Kutner (20th century)
