Why is the Mercator map still in use today?
Why is the Mercator projection map still in use today? It is useful to sailors because, although size and shape are distorted, it shows directions accurately. Mercator projections help sailors to navigate.
Why is the Mercator projection inaccurate?
Mercator maps distort the shape and relative size of continents, particularly near the poles. 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.
What are two problems with the Mercator map?
Because the linear scale of a Mercator map increases with latitude, it distorts the size of geographical objects far from the equator and conveys a distorted perception of the overall geometry of the planet.
Why are some countries sizes distorted on a Mercator map?
Why does this happen? This distortion is because of something called the Mercator Projection. In 1569 he designed a map that could be accurately used for navigation purposes, but the downside was that his system distorted the size of objects depending on their position relative to the equator.
Why is the world map not to scale?
Because the earth is a sphere – more of a potato-shape, in fact – it is impossible to map it on a flat surface without errors in proportion, explains Kraak. Also the Peters projection has its flaws. In order to show the actual size of land masses, their shapes are distorted.
How is a Mercator map distorted?
Although the linear scale is equal in all directions around any point, thus preserving the angles and the shapes of small objects, the Mercator projection distorts the size of objects as the latitude increases from the equator to the poles, where the scale becomes infinite.
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 is the problem and disadvantage of the Mercator map?
What is the problem and disadvantage of the 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.
How do Mercator projections distort?
What does not scale mean?
Adjective. not-to-scale (not comparable) Presented at a size other than to-scale. The sketch is a not-to-scale drawing of the workpiece with cut surfaces highlighted by heavy lines.
Why is the Mercator projection the most common representation of the globe?
One of the most famous map projections is the Mercator, created by a Flemish cartographer and geographer, Geradus Mercator in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant true direction. Also, the lines of longitude are evenly spaced apart.
