| Aug 11, 2016 at 14:50 | comment | added | J. M.'s missing motivation♦ | Is the domain of that blobby image also $\lambda\in(-180^\circ,180^\circ),\; \phi\in(-90^\circ,90^\circ)$? I would certainly need a way to align the blob with the map. | |

@J.M. You can use e.g. this, it's fast enough: Binarize@Blur[Dilation[Graphics@{Black, Table[Rotate[Disk[{RandomReal@{-10, 10}, RandomReal@{-1, 1}}, RandomReal[{0, 3}, {2}]], RandomReal@{0, Pi}], {100}], White, Table[Rotate[Disk[{RandomReal[{-10, 10}], RandomReal@{-1, 1}}, RandomReal[{0, 0.8}, {2}]], RandomReal@{0, Pi}], {30}]}, DiskMatrix@5], 25]. The point (which makes this globe-making business hard) is that if parts of the blob distribution are over see, those parts should be omitted.

| Aug 10, 2016 at 20:35 | comment | added | J. M.'s missing motivation♦ | Do you have a sample distribution map I can use? That seems as if it will need more work, but it ought to be doable. | |
| Aug 10, 2016 at 20:32 | comment | added | István Zachar | @J.M. Yes, I'm interested, as I'm still working on this problem, with no definite solution. If your method can also be tweaked to overlay a distribution map over a 3D globe, then of course, post it here! If not, I would suggest a separate thread, but I certainly would like to see it anyway! | |

| Apr 24, 2012 at 12:33 | comment | added | Mark McClure | I stand by my second answer, which projects polygons onto the sphere. In my answer, the original countries can be taken as regions. It needs one improvement, namely the FullPolygons should be simplified. I have code for this which I could post later. Is it possible for you to get the triangle command working from the command line? | |

| Apr 24, 2012 at 9:57 | comment | added | István Zachar | @MarkMcClure: I used a random blot from here, any will suffice. | |
| Apr 24, 2012 at 9:54 | comment | added | István Zachar | @R.M Yes, I agree with you, though on the other hand, I did feel that they are heavily intertwined issues: I've tried many things, and realized that if I change e.g. the method of graphics-intersection then I have to change the method of projection as well. And to be honest, when I posted this thing weeks ago I had the intention to post exactly the question I asked yesterday. But since I was way behind my idea, I had to do my research in the meantime. I know that it is now a complex issue, that's why I've tried to soften the blow with the bounty. | |

While I'm a huge proponent of OPs editing their question to update with more info, here, the question went from 1) "What's the logic behind CountryData" to 2) "How to make a 3D globe" to now 3) "Plot geographic data over a 3D globe" over the course of a month! I think this is excessive— questions should be updated with info, not changed in scope! It makes Fx's and FJRA's answers look completely out of place. It's also on the verge of being bumped to CW, for those who care. I think that this should've been 3 separate questions or one well thought out question. It's too late to do anything now

To avoid the strange spirals I used: Texture[Rasterize[pic, ImageSize -> 1500]] instead of Show in Mark's code.
