Does Mercator show direction?
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. As a side effect, the Mercator projection inflates the size of objects away from the equator.
What was Gerardus Mercator known for?
Gerardus Mercator, original name Gerard De Cremer, or Kremer?, (born March 5, 1512, Rupelmonde, Flanders [now in Belgium]—died December 2, 1594, Duisburg, Duchy of Cleve [Germany]), Flemish cartographer whose most important innovation was a map, embodying what was later known as the Mercator projection, on which …
How was the Mercator projection created?
The Mercator projection was originally developed in 1569 by the Flemish cartographer Gerardus Mercator. Mercator found that to keep the rhumb lines straight he had to make lines of latitude move away from each other as they moved north and south of the equator.
What did Mercator achieve with his map projection of the world in 1569?
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. It was also easier to see the relationships between landmasses.
Why is the Mercator map still in use today?
Mercator World Map. Geradus Mercator’s world maps flattened the spherical planet to make it easier to display. Displays of the landmasses are not necessarily proportional to their actual size, especially toward the poles. Despite these distortions, his maps are still in heavy use.
Why do maps show Greenland so big?
In Mercator maps, the Earth’s surface is projected on a cylinder that surrounds the globe (Fig. 4). The cylinder is then unrolled to produce a flat map that preserves the shapes of landmasses but tends to stretch countries towards the poles. This is why the size of Greenland is exaggerated in many world maps.
What is the most accurate map projection to date?
The lower the score, the smaller the errors and the better the map. A globe of the Earth would have an error score of 0.0. We found that the best previously known flat map projection for the globe is the Winkel tripel used by the National Geographic Society, with an error score of 4.563.

Why are flat maps not accurate?
Size Matters Flattening a three-dimensional globe onto a flat surface isn’t possible without some distortion. Mercator maps distort the shape and relative size of continents, particularly near the poles.
Which map projection has no distortion?
globe
What is the Robinson projection good 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.
What is the disadvantage of the Robinson projection?
Advantage: The Robinson map projection shows most distances, sizes and shapes accurately. Disadvantage: The Robinson map does have some distortion around the poles and edges.
Is Mercator or Peters map better?
In addition, Mercator only distorts longitudinal distances (except very close to the poles), whereas Peters screws up the scale almost everywhere for both longitude and latitude. This is why Mercator beats out Peters in the world of cartography, and why Google Maps uses a modified Mercator projection.
What distortions are worse on Goode’s projection?
Shapes, directions, angles, and distances are generally distorted. The scale along all parallels in the sinusoidal part, between 40°44’12” north and south, and along the central meridians of the projection is accurate.
