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 car as we know it is on the way out. To a large extent, I deplore its passing, for as a basically old- fashioned machine, it enshrines a basically old-fashioned idea: freedom. In terms of pollution, noise and human life, the price of that freedom may be high, but perhaps the car, by the very muddle and confusion it causes, may be holding back the remorseless spread of the regimented, electronic society.”
—J.G. (James Graham)
“A cow does not know how much milk it has until the milkman starts working on it. Then it looks round in surprise and sees the pail full to the brim. In the same way a writer has no idea how much he has to say till his pen draws it out of him. Thoughts will then appear on the paper that he is amazed to find that he possessed. “How brilliant!” he says to himself. “I had no idea I was so intelligent.” But the reader may not be so im pressed.”
—Gerald Branan (1894–1987)
“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)
