# Why are polar regions distorted in Mercator projection?

## Why are polar regions distorted in Mercator projection?

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. …

### What is the main problem with a Mercator map?

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.

Why don’t we use the Mercator map?

Mercator is NOT well suited for navigation It’s true that lines of constant compass bearing appear straight on the map. But lines of constant compass bearing are in fact curved. Looking at a Mercator map, you would think it’s a straight route across the ocean.

Why do we use the Mercator 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. All the latitude and longitude lines intersected at 90-degree angles.

## Why is the Mercator map used for navigation?

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 do we use Mercator map?

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.

Why is Mercator used?

Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. 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.
