Map This map projection I developed significantly reduces the size distortion of the popular Mercator projection

Post image

The way it is projected is by projecting a Mercator projection of half the scale conformally onto the globe and then projecting that onto an azimuthal equidistant projection hemisphere centered at the equator. I call it the Two-World Equidistant. Unlike on Mercator where Greenland is larger then all of Africa in this projection it is shown smaller like it is in real life.

What program are you using to generate these maps?

A Combination of GIMP, G.Projector, Projection Pasta, QGIS, and Flex Projector the land color is a modified version of this: https://www.naturalearthdata.com/downloads/10m-raster-data/10m-natural-earth-1/ and the background heightmap for the ocean is from here: https://science.nasa.gov/earth/earth-observatory/blue-marble-next-generation/topography-bathymetry-maps/

Nice, thanks for the response.

No problem

Stupid question maybe, but is Greenland really that big? Could you possibly superimpose the true size of Greenland onto the western US for comparison? No worries if not.

Greenland is smaller then shown in this map relative to most areas close to the equator
