I built one, tracking fleet vehicles with a custom box, using tiled maps, on behalf of Vodafone, back in 2002. I still remember I wrote a basic trans-mercator library too!
Of course Mercator projection may go out of fashion soon https://www.independent.co.uk/news/world/africa/world-map-eq... :)
Hope I'm called back to update the library ;)
Probably not if navigation is involved:
> This is why most online mapping platforms like Google Maps or Apple Maps rely on a variation of the Mercator projection to provide directions. Using the Equal Earth projection for navigation would not be as effective as the Mercator projection.
> What the UN did was endorse the broader message that Equal Earth is a fairer projection that more equitably displays the true size of the Earth’s land
You are right about this though - it's a moral fashion. Who cares about land size on a map unless you've got the priorities and advancement of a prehistoric king? People with plenty of spare time who constantly talk in an echo chamber[0], that's who.
