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. …
What are the advantages of a Mercator map?
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 Mercator projection map used for?
Description. Mercator is a conformal cylindrical map projection that was originally created to display accurate compass bearings for sea travel. An additional feature of this projection is that all local shapes are accurate and correctly defined at infinitesimal scale. It was presented by Gerardus Mercator in 1569.
How did the Mercator projection give an advantage to colonial powers?
Other critics say that this projection and the large size of continents like Europe gave an advantage to the colonial powers because it made them appear larger than they really are. This advantage eventually led to the lack of development in many equatorial regions that appear smaller on the Mercator maps.
Why is a Mercator projection best for sea travel?
For purposes of navigation preserving angles is the most important property. The exact method that Mercator used to create his map is not known. He probably used graphical means using a compass and a straight edge.
What is a positive of the gall Peters Projection?
It is a simple way to highlight the borders of each continent. Because of the equitable size features that are found on the Peters projection, it is very easy to highlight the different continents on the planet for learning purposes. This benefit is quite useful for determining the border between Europe and Asia.
What is the advantage of the map projection?
Advantage: The Equal-Area map projection show the correct sizes of landmasses and continents. Disadvantage: The Equal area map causes the shapes of landmasses to be altered and forced into curves.
How does the Mercator projection work?
To keep longitude lines straight and maintain the 90° angle between the latitude and longitude lines, the Mercator projection uses varying distances between latitude lines away from the equator. As a result, the Earth’s poles and landmasses closest to them are distorted.
Why do you think it was so important for the creator of the Mercator map to ensure that proper direction was maintained?
In 1569, Mercator developed a better, more accurate projection. His new map was a revelation, because the projection kept the latitude and longitude lines at consistent 90 degree angles. These clean angles made it easier for sailors to plot their course without constantly adjusting for mapping mistakes.
How is Mercator projection used in navigation charts?
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. It is less practical for world maps, however, because the scale is distorted; areas farther away from…
Who was the first person to use Mercator projection?
Gerardus Mercator. …his name in the “Mercator projection,” which he used on his map of the world in 1569.…. navigation chart. …century they were replaced by Mercator projection charts that showed compass directions as straight lines.
When did Gerardus Mercator create his map of the world?
This projection became known as the Mercator projection and was used on his map of the world in 1569. In 1569 and throughout the 1570s Mercator began a series of publications to describe the creation of the world through maps.
What was the latitude of the Mercator 1569 map?
Mercator 1569 world map ( Nova et Aucta Orbis Terrae Descriptio ad Usum Navigantium Emendate Accommodata) showing latitudes 66°S to 80°N. The Mercator projection ( / mərˈkeɪtər /) is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569.
