After over 3 months in the making, I finally decided to post this article. I originally wanted to post this back in January during version 5.3, but work has taken most of my time, so this was eventually postponed all the way to 5.5, and just a day before the...
Interrupting pseudocylindrical maps It turns out that most, if not all, pseudocylindrical and similar types of maps can be interrupted. NASA’s G-Projector software supports interruptions of some pseudocylindrical projections (Goode homolosine, Mollweide, Sinusoidal) but unfortunately doesn’t offer it for most other pseudocylindrical projections. For example, the McBryde P3, which is...
New pseudoazimuthal projections It turns out it’s actually quite easy to make pseudoazimuthal projections without the knowledge of making the equations for it. They are made by halving the longitudes, projecting it to an azimuthal projection, and stretching the result into a 2:1 ellipse. Using an image editor and map...
The AuthaGraph projection is overrated: Here’s why Back in 2016, the AuthaGraph projection took the media by storm when it was awarded Japan’s Good Design Grand Award. News outlets claim it to be “the most accurate ever” or any other sensational claims. However, I feel like this projection is severely...
Tetrahedral projections AuthaGraph Top: The official AuthaGraph mapAbove: The projection's clone applied to a silhouette map of the Earth Pros: Minimum-error projection: balances out areal and angular distortions to an acceptable degree. Good placement of landmasses to avoid severe distortions. Won the Japanese Good Design Grand Award in 2016. Probably...
Some map stuff I’ve been playing around with map projection and GIS tools for a while now, ever since I got addicted to the MapPorn subreddit and seeing some good-looking high resolution maps. Reprojecting a Mercator map into an Equirectangular one I got a bit bored after reprojecting an equirectangular...
