How did you look at that bin file into Wilbur? Does G-Plates support bins?
How did you look at that bin file into Wilbur? Does G-Plates support bins?
In Wilbur, use File>>Import Subsection and enter the data shown above. If I recall correctly, the raster was flipped vertically, so Surface>>Rotate>>Flip Vertically gets it back to its original orientation.
I don't know what G-Plates supports for its input formats, but there may be one that Wilbur can export if a .bin file isn't natively supported.
Can Wilbur convert a map like this into equirectangular?

Can you try to convert the map?
Wilbur doesn't do arbitrary reprojections to equirectangular, that's more what ReprojectImage does. That looks pretty much like a Miller Cylindrical projection. ReprojectImage didn't do well with it, most likely because Reprojectimage was never intended as a high-accuracy tool (it's as good as you're willing to clumsily adjust things).
Anyhow, here's what fell out (it's upside down, but I think that you can fix that):

I didn't convert anything. I downloaded the Digital Elevation Model (DEM) file https://ddfe.curtin.edu.au/models/Ea....1min.geod.bin from the author's website as I said above. That file is already in a special variant of the Equirectangular projection that has the cells equal in latitude and longitude ( https://en.wikipedia.org/wiki/Equire...lar_projection see the special case "geographic projection").
Well, when I imported the bin file in Wilbur and used your settings, it turns out that the map looked like this. Solutions?

That's the png file that accompanies the bin file on the author's web site. You can tell because it has all of the labels and stuff that's missing from the straight DEM (plus, Wilbur will never generate that color scheme unless you go to a lot of effort to enter it). The .bin file is 455MB in size, while the accompanying .png file you showed above is 850KB.
Sorry for not elaborating, but I was more referring to the projection of the map. It didn't have the standard equirectangular map, it had the projection shown in the image I showed while I imported the bin file into Wilbur. So, what did you do differently that caused you to have that equirectangular map?
Use Surface>>Size with width 21800 and height 10800 to get a surface that's the size of the data set you want to import. You can use a smaller image if you want, but make sure to keep the 2:1 width:height ratio.
It ended up working! Thanks for that!
However, I do have three questions.
1. Keep the ratio in what area? Because 21800 is not twice as much as 10800. So, is the ratio there? Or is it in 21600 or 10800?
2. How do you retain the colors? Because when saved it as a PNG, it lost the color, and it became black and white.
3. If you are able to make the colors stay, can I change the color palette itself? Specifically in this image?

And this is the color legend.
