The Mercator Projection: A Map with Distortions and Benefits
TLDR The Mercator Projection, created in 1569, is still widely used today despite its flaws. While it accurately represents the shape of objects, it distorts their size, making it less suitable for displaying the entire Earth.
Timestamped Summary
00:00
The Mercator Projection is a map that was created in 1569 and is still in use today, despite its problems and benefits.
01:29
The Mercator projection is a cylindrical projection that attempts to put a sphere onto a flat surface, but all projections will distort size or shape in some way.
02:57
Gerardus Mercator created the Mercator projection in 1569, which was the first attempt to systematize what was on a globe with what was on a map and preserve angles for navigation purposes.
04:30
The Mercator projection is widely used in digital maps because it accurately represents the shape of objects, but it distorts their size.
05:54
The Gaul-Peters projection is an equal area projection that preserves size but sacrifices shape, making it look odd to most people.
07:23
The best world wall maps are pseudosylindrical projections, which preserve both size and shape, and National Geographic has used this approach with its world maps for several decades, while the host uses the Kevrisky 7 projection for the world map on his personal travel website.
08:43
The Mercator projection is useful for navigational mapping but has flaws when displaying the entire Earth, so a globe or non-cylindrical projection is a better choice for a world map.
