Is it possible to apply the Equal Earth projection (=EPSG8857 to 9?) in GMT ? Thank You. ---

I was waiting that this question was coming. The general answer is: we can use any projection supported by PROJ (Equal Earth is), but GMT won’t able to plot the frames (and the grid but not so sure here) and annotations for the non-supported projections (eqearth is not) ---

Codes for WGS 84 / Equal Earth Greenwich EPSG:8857 work: -Rd (centered on Greenwich) -R-180/180/-90/90 but these ones give incorrect results: -Rg (centered on dateline) -R-270/90/-90/90 (WGS 84 / Equal Earth Americas EPSG:8858) -R-30/330/-90/90 (WGS 84 / Equal Earth Asia-Pacific EPSG:8859) ![GMT_Equal_Earth](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/a/a046b4efddf7a79adc665809080fed03687460ba.png) In case of Eckert IV (-JKf) they work well. ---

Yes, its does include everything in master at the time of what is in the name. And no, it won’t go into main gmt page. For many years I have kept developing version, updated time to time, in the Mirone site. I’ve also started to devise a mechanism to allow a continuous rolling updating mechanism, but that’s far from trivial and would work on windows only. ---
