A software thing I built: GPS on a 25MHz 486-SX

    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 <a href="https:&#x2F;&#x2F;www.independent.co.uk&#x2F;news&#x2F;world&#x2F;africa&#x2F;world-map-equal-earth-projection-un-mercator-b3050761.html" rel="nofollow">https:&#x2F;&#x2F;www.independent.co.uk&#x2F;news&#x2F;world&#x2F;africa&#x2F;world-map-eq... :)

    Hope I&#x27;m called back to update the library ;)

      Probably not if navigation is involved:

      &gt; 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.

      &gt; 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&#x27;s a moral fashion. Who cares about land size on a map unless you&#x27;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&#x27;s who.
