What is a Mercator in geography?
Mercator World Map His most famous work, the Mercator projection, is a geographical chart where the spherical globe is flattened into a two-dimensional map, with latitude and longitude lines drawn in a straight grid.
What is Mercator projection method?
The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569.
What does Mercator projection mean in history?
The Mercator projection was mainly used for maps. This made it possible for the entire globe to be drawn on a flat sheet. It is also used for marine navigation since the lines of constant direction appear as straight lines on the map.
What is an example of a Mercator projection?
On a Mercator projection, for example, the landmass of Greenland appears to be greater than that of the continent of South America; in actual area, Greenland is smaller than the Arabian Peninsula. This article was most recently revised and updated by Michael Ray.
What is Mercator chart good for?
A cylindrical map projection in which the meridians and parallels appear as lines crossing at right angles and in which areas appear greater farther from the equator. Straight line segments represent true bearings, thus making this projection useful for navigation.
What are the 3 advantages of the Mercator projection?
Advantages of Mercator's projection: - preserves angles and therefore also shapes of small objects - close to the equator, the distortion of lengths and areas is insignificant - a straight line on the map corresponds with a constant compass direction, it is possible to sail and fly using a constant azimuth - simple ...
Is Google maps Mercator projection?
We accept imagery projected using a standard cartographic projection such as Universal Transverse Mercator (UTM), a satellite-based datum such as GRS80, or WGS84; or in Geographic Coordinates (aka "latitude/longitude") with WGS84 datum.
Are Mercator maps still used today?
The Mercator projection is, however, still commonly used for areas near the equator where distortion is minimal. It is also frequently found in maps of time zones.
Is Mercator map accurate?
Mercator maps distort the shape and relative size of continents, particularly near the poles. This is why Greenland appears to be similar in size to all of South America on Mercator maps, when in fact South America is more than eight times larger than Greenland.
What are the advantages and disadvantages of the Mercator projection?
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. Who Uses it? Sailors use a Mercator map to navigate.

What is Mercator projection for kids?
The Mercator projection—a transformation from the simple cylindrical projection—is used for navigation, since lines of constant direction on the Earth appear as straight lines on the map.

What does the name Mercator mean?
Mercator as a boys' name is of Latin origin, and the meaning of Mercator is "merchant". Latinate name of Gerardus Kremer, the 16th-century cartographer whose projection for a world map was useful to navigators.
How popular is Mercator?
Mercator is an unusual first name for men and an unusual last name too for all people. (2000 U.S. CENSUS)
What is a mercator?
Mercator noun. Pertaining to an orthomorphic map projection, in which meridians appear at right-angles to the equator, and lines of latitude are horizontal lines whose distance from each other increases with distance from the equator. Etymology: Latinized name of , Flemish cartographer and mathematician. Mercator noun.
What is mercator growth?
Mercator has an ambitious growth plan which is a mix of organic and acquisition-led growth, as we see opportunities in the market to acquire innovative technology and platforms we will be prone towards action.
Who created the Mercator?
There is some controversy over the origins of the Mercator. German polymath Erhard Etzlaub engraved miniature "compass maps" (about 10×8 cm) of Europe and parts of Africa that spanned latitudes 0°–67° to allow adjustment of his portable pocket-size sundials. The projection found on these maps, dating to 1511, was stated by Snyder in 1987 to be the same projection as Mercator's. However, given the geometry of a sundial, these maps may well have been based on the similar central cylindrical projection, a limiting case of the gnomonic projection, which is the basis for a sundial. Snyder amends his assessment to "a similar projection" in 1994.
What is a mercator projection?
The Mercator projection maps all lines with constant bearing ( rhumbs (mathematically known as loxodromes—those making constant angles with the meridians) to straight lines. The two properties, conformality and straight rhumb lines, make this projection uniquely suited to marine navigation: courses and bearings are measured using wind roses or protractors, and the corresponding directions are easily transferred from point to point, on the map, with the help of a parallel ruler (for example).
How is the Mercator projection determined?
The Mercator projection is determined by the requirement that the projection be conformal. One implication of this is the "isotropy of scale factors", which means that the point scale factor is independent of direction, so that small shapes are preserved by the projection. This implies that the vertical scale factor, h, equals the horizontal scale factor, k. Since k = sec φ, so must h .
Why did Mercator use sinusoidal projection?
Because of great land area distortions, some consider the projection unsuitable for general world maps. Therefore, Mercator himself used the equal-area sinusoidal projection to show relative areas. However, despite such distortions, the Mercator projection was, especially in the late 19th and early 20th centuries, perhaps the most common projection used in world maps, despite being much criticized for this use.
Why is the Mercator projection used in navigation?
It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator.
Which projection exaggerates areas far from the equator?
The Mercator projection exaggerates areas far from the equator .
Why is a marine chart based on a mercator?
Practically every marine chart in print is based on the Mercator projection due to its uniquely favorable properties for navigation . It is also commonly used by street map services hosted on the Internet, due to its uniquely favorable properties for local-area maps computed on demand. Mercator projections were also important in the mathematical development of plate tectonics in the 1960s.
