LOVELAND, OH (March 5, 2024) – In Issue 2024-42, we “rewind” to March 5, 2021 to learn more about navigation by projection while Steve Kovacs enjoys a one week Fun with Maps R & R. 


Today is the birthday of Gerardus Mercator, one of the key figures in the history of cartography.  He was born in 1512 in modern day Belgium.

His name bears the projection he invented and first published in 1569 that utilizes constant bearing rhumb lines which are super helpful for navigating ships.  This projection gained slow acceptance but the newer world maps (19th century onward) tend to use this projection, as do nautical charts.  The criticism of Mercator Projection is that artificially enlarges features closer to the poles.  So, for example, it makes Greenland look much bigger than it really is.
