Hi there everybody. I subscribed this site some months ago but since my progress have been very spaced out due to family deeds, and since I had to surrender using GIMP (too few time to learn a new instrument the right way), I had some hard time posting on the board. Now I started to work slowly but steadily on my personal project and I'd like to have authoritative feedback both on my "rookie" efforts and on my basic idea.

About the project

All started when I thought about building a custom setting to drive a fantasy campaign with my fellows role players. I'm kinda family guy, dad and all the rest, so my time is very short. But since I role play without pauses since when I was young, I've never been scared by long time efforts. What I needed was a map, I ended up here and I found Saderan tutorial (which map stunned me for its beauty). Since my other passion (and my job) is programming and I do it the free/open-source way, I thought I could join the two mindset and provide my map for free to everybody to build their campaign settings on.
But soon I realised that a full-fledged world is hampering when you're building your setting. I mean, I would never use another setting map "as-is" as I want to choose where to place people, how to call cities, and so on. On the other side, building the whole world is a long process. The solution I've found to this dilemma is the core idea of my project. As I learned here, a fantasy world could be built bottom-up using what we can call a "multilayer protocol". First geology, than life forms, then people migrations, civilisation, social layer etc. This is a recurring concept in computer-science and I'd like to apply it to some sort of free/open world-building project, providing the first layer of the stack.
What I'd like to end up is a founding geological map that will be freely available in many levels of detail, so that it could be redrawn to fit many styles. My plan is to release the landmasses schema when I'll be happy with it on a dedicated site, then publish more detailed close-ups of the whole landmass, and in the end start working out my Saderan-like version of the world. In the meantime the site will be open to contribution based on the same landmass, so that the world could be redrawn (either entirely or region by region) in many different styles to fit many different settings. The rule of thumb will be that only geological maps, without cities/rivers etc. will be considered contributions. A full-fledged map will be considered derivative work. Obviously nothing prevents people to post the geological base of a derivative work as a contribution, so that others could take advantage from it.

About the world itself

Given my goals, I'm trying to conceive a map that even if imaginary, could be considered likely. After some bad attempt I came up with this:

Here I have tried to draw taking continental drift into account, given that I imagined it shaped by two spiralling movements, one big on the right and one smaller on the upper left.
I also included poles landmasses. The north one is intended to be a true continent (as our south pole), while in the south I imagined icy islands slowly (on a geological time scale) drifting around the pole.
I think this shape could be a good kickstart for a lot of different justification, thus enriching settings based on the map, given that authors would like to take this into account.
I tried to figure out the scale of this all, overlapping a true photographic shot of our earth, but I ended up thinking that this will definitively be an "application-related" issue.

Don't bother with lakes, since they are there just because I didn't addressed them yet. I still don't know if getting rid of them for the very basic "shared landmasses" or fixing their position, as well as rivers and relieves to give consistency to the whole, allowing contributors to just decide on climate and its effect on plant distribution, deserts and such. Obviously climate could result in empty basins, but well... I think I've made my point!

Now what I'd like to ask you is... advices and critics! Both on my idea and on the map itself.
Sorry for the looooong post and thank you for any feedback I'll receive.

PS: if someone could come up with a good name for such a project, he/she will be paid in beers!
PS2: my English is far from good, so please be patient if I wrote something wrong or "odd"... just point it out and I'll try to avoid errors in the future.
