WIP: unnamed Earh-like planet

[groovey]

The last two posts made me think a lot, my head hurts (don't get me wrong, I'm not scared of thinking, on the contrary, I love it, but I'm more fit for social science, I'm an Historian after all. Natural science on the other hand is much more complex for me to grasp). They made me realize I do need to place islands on some oceanic boundaries and that to know where exactly I need to know the rotation axis on the plates (the Euler pole Pixie introduced me to, and the technique he came up to represent it on PS or GIMP is both simple and effective, it does help me indeed), which will also help me solve my problem of not knowing the boundaries movements.

However, I'm going to need a lot of processing to figure it out and fix the map.

Quick question:

- Islands originated in divergent boundaries TEND to be smaller than those created on convergent boundaries, true or false?

- So when two continental collide, if subduction doesn't occur, how do you represent it on a map? With what symbol?

Pixie, you mean this WIP of yours? http://www.cartographersguild.com/re...ke-planet.html. I've checked it out a few times. I love what you did with the heightmap on that lovely pinguin, and observed your tectonics as a reference, so if you are going to re-do or edit the tectonics of the map, please, will you be so kind to post the updated tectonics?

Well, yes, I figured. My map will also need a lot of re-processing. Furthermore, since I found out that rotation gives very different results depending on the projection.. And then I searched the web reading stuff about it and it seems (as sure as I can be now) that the projection to get this right needs to be stereographic.
So, my task will be, in the near future, to create stereographic projections of my original map. Several of them (stereographic projection, which G.projector can produce, cannot show a whole sphere at once), one for each plate, centered on it. And then work out their movement.

The only islands on divergent boundaries is when they coincide with a hotspot - Iceland and Azores are the only examples I can think of (as they are closest to me - I reckon most of the times it's actually no islands formed!
Even though there is no actual subduction (plate sinking and melting), I think it is represented in the same way (this is a detail we can very much not worry about)

Yes, that's the world I am working on for some time. And yes, once I find the time to reconfigure tectonics I will post updates... Again, groovey, thanks for making be rethink my knowledge on tectonics and improve my own map .
