What is Robinson Mercator projection?
Unlike the Mercator projection, the Robinson projection has both the lines of altitude and longitude evenly spaced across the map. In opting for a more pleasing appearance, the Robinson projection ‘traded’ off distortions – this projection is neither conformal, equal-area, equidistant nor true direction.
What are advantages and disadvantages of Mercator?
Advantage: The Mercator map projection shows the correct shapes of the continents and directions accurately. Disadvantage: The Mercator map projection does not show true distances or sizes of continents, especially near the north and south poles.
What is the biggest problem with Mercator projection?
One problem is the variation of scale with latitude, and another is that straight lines on the map (rhumb lines), other than the meridians or the equator, do not correspond to great circles. The distinction between rhumb (sailing) distance and great circle (true) distance was clearly understood by Mercator.
What is a Robinson projection map used for?
The Robinson projection is unique. Its primary purpose is to create visually appealing maps of the entire world. It is a compromise projection; it does not eliminate any type of distortion, but it keeps the levels of all types of distortion relatively low over most of the map.
Is Robinson better than Mercator?
Robinson (1963) Robinson makes the world “look right”. Better balance of size and shape of high-latitude lands than in Mercator. Russia, Canada, and Greenland truer to size, but Greenland compressed.
What is the advantage of using the Mercator map?
One advantage of using the Mercator projection is that there are parallels and meridians to cross one another at right angles, just as they do on the globe. As a result, the direction is true everywhere on his map, a very important fact for anyone traveling east to west, or vice versa, on the Atlantic.
What is the Mercator map most useful for?
This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. …
Is the Mercator map wrong?
The popular Mercator projection distorts the relative size of landmasses, exaggerating the size of land near the poles as compared to areas near the equator. This map shows that in reality, Brazil is almost as large as Canada, even though it appears to be much smaller on Mercator maps.
What is the Mercator projection good for?
This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course.
Why is Mercator projection used?
In 1569, Mercator published his epic world map. This map, with its Mercator projection, was designed to help sailors navigate around the globe. They could use latitude and longitude lines to plot a straight route. Mercator’s projection laid out the globe as a flattened version of a cylinder.
