the Mercator projection
Navigators use a Mercator projection chart to plot great circle routes. This chart allows them to draw a straight line, which represents the shortest distance between two points on a curved surface such as the Earth. By following this route, ships and planes can save time and fuel compared to following a rhumb line route.
All map projections put the earth's surface on to a flat sheet, in different ways. For navigation the Mercator projection is very common because a line on a constant compass bearing is shown as a straight line in this projection. Mercator is an example of a conformal projection because the shape of a small feature - like an island - is preserved on the map. Other projections preserve area or direction, but no projection can achieve everything, it's always a compromise.
how navigators and sailors
The Mercado projection is a map projection that preserves the shapes of continent to minimize distortion. It is often used to represent regions near the equator with less distortion in shape and direction.
Usually a computer. Most navigators do not have the skill to do this by themselves any more.
True. The projection note for any map sheet identifies the projection system used on the map sheet.
A map projection that is used for sea travel includes the gnomonic projection. This was most often used to find the shortest routes between points on a sphere.
No, a multiview projection is used for developing a multiview drawing. Multiview projections are orthographic projection where the object is behind the plane of projection, and is oriented such that only two of its dimensions are shown.
thrid angle projection is officially used in Australia, for a fact, not lying!!
Discounting the Mercator, which cartographers tend to HATE but is ubiquitous anyway... Probably the Lambert Conformal Conic projection, or the Lambert Azimuthal Equal-Area projection (used by the US National Atlas).
Early navigators would have used ships and boats for much of their travels. Stagecoaches became available later. Many miles were also navigated on foot.
Three projection methods used by geographers and map makers are: cylindrical conic planar.
