#mercator

Happy birthday to Gerardus Mercator (1512-1594) renown Flemish cartographer.
What made Mercator a great #cartographer, was in fact his abilities as a #mathematician -and like those of us scientists who feel compelled also to create art he was wasn’t hindered by his immense ability as an engraver. He produced beautiful world maps (a version of which is depicted in this print), globes,

[note the ‘true’ size of high latitude landmasses like Greenland and Canada (and Russia as well); note also that the Mercator Projection was not / is not a ‘tool of colonialism’, geopolitics or the like, it was/is ‘simply’ a very clever projection to aid in marine navigation]

@tagesschau die #Landkarte ist offensichtlich völlig ungeeignet um zu zeigen, dass Grönland sechsmal so groß wie Deutschland ist. Auch der eingeblendete Maßstab gilt in hohen Breiten nicht. #Mercator ist für die Polarregionen völlig ungeeignet! @TerribleMaps

CFC begone #mercator and your colonialismus!
Might be that I just released version 0.62.1 of #TinyWeatherForecastGermany . 
The #changelog : https://codeberg.org/Starfish/TinyWeatherForecastGermany/src/branch/master/CHANGELOG.md
The perhaps biggest change is the switch to an #osm #map in #mercator projection.
The weather warnings and the rain radar are more accurate now, and the map is more detailed.
Also, you now can (again) resize all widgets without an upper size limit. 
Fingers crossed that #fdroid will build the new version without issues.
Have fun!

Cool to see map geekiness pop up on network TV drama a few years back

• I am NOT a fan of the the Galls Peters - thinking that the Equal Earth Projection (https://equal-earth.com/) is vastly superior technically and ‘aesthetically pleasing’
• The 1569 Mercator projection was NOT designed as a ‘tool of cultural oppression’, that is a persistent myth - but rather was "... 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 Trekkie, I also love that the actor John Billingsley - who plays Dr Flox - is the ‘lead scientist’…

This is a great image. It helps debunk the baseless conspiracy theory, i.e. Mercator map was meant to support racism and make Europe look bigger. In fact the biggest area distortions of the #Mercator map are #Siberia, #BaffinIsland, and #Antarctica, all of which are almost entirely unpopulated. The actual reason for this particular map projection is merely ease of early, pre modern science, ocean #navigation:

Useful reminder. Though it is equally useful to remind readers that these #mercator projection #maps are not a reflection of #Eurocentrism: they were designed primarily for navigation purposes, thus not at all intended as a realistic representation of actual space

This map by Neil Kaye, true size vs #Mercator projection, was a disorienting revelation in my quest to figure out how #EarthSystem|s work and how they evolved in the past 6Ma or so, since the #Pliocene . Staying aware of how small the land mass in the Northern Hemisphere really is is nigh impossible and contrarian to its importance to weather and climate. Just look at tiny Greenland...!
I wonder how a true-size 2D-version for oceans and landmass would look and feel?
