Sorry for getting back to this so late

We originally set this up to allow non-fgdata committers to commit canvas related contributions to a single repository - since then, MapStructure development has stalled a bit.
These days, it's primarily artix who's been doing most related development.

Originally, the idea was to regularly sync back useful changes so that they appear in the "upstream" fgdata repository.

Since then, quite a few things have changed - including the fgdata/fgaddon split, but also gitorious shutting down, which is why we're lagging a bit behind.
Also, gitorious announced that they'd shut down all repos at the end of May IIRC - but it seems quite a few repositories/projects are already no longer reachable unfortunately.
So there's that too.

What exactly do you need ? Or do you just want to follow MapStructure development ?

My suggestion would be to clone fgdata, and ask artix/RevHardt to mirror their work - and we'll do the same, so that everything should be backed up.

Thx Hooray
I am current follow the development of MapStructure for my project Farmin.
And i wand to have some slippy map support using a non mouse cursor for selecting objects and showing the current ground altitude as a layer.

I once experimented with interactive/edit-able layers, drag & drop is trivial to support - but interactive editing is a bit more involved.
I think the cursor can be easily changed using a property IIRC - ground elevations can be easily queried using a geodinfo() call that is invoked by a Canvas event listener, so no problems there.

However, I don't think there were any recent changes relating to these things, so what you see in fgdata is basically the latest state, because all the other efforts are unrelated as far as I can tell, i.e. shouldn't affect your work.

When it comes to MapStructure, my suggestion would be to follow the commits made by artix and RevHardt - who are currently the primary MapStructure users, and whose work is likely to be reviewed and committed "upstream" at some point.

ok, thanks for the update - much appreciated.
it's good to know that you've been able to retrieve the whole repo.
However, it would actually make sense to provide a down-stripped repository without any aircraft included.
I also need to check if any of the committers recently committed to any of the branches there.

I've seen that now fgdata has been split (great work). How should we sync canvas hackers fgdata with main fgdata after this split?

Another question:
what do you think about converting the current canvas hackers fgdata repo to a branch of the main fgdata repo? By this way it should be easy to keep it in sync with main fgdata developments.

One way you could possibly achieve it is do a diff from master to the canvas-hacker branch, and then apply that to a new fgdata. It's fine it that includes one or two aircraft you're developing canvas on – you would have to copy the test of the aircraft too. Or you could just delete the aircraft directories, if you're not comfortable with developing the aircraft in FGData.
Thanks,

www2 you have mentioned you want to do a slippy map. I've just put some old code of me in the wiki showing how to build a simple tile map: http://wiki.flightgear.org/Canvas_Snipp ... e_tile_map There are some issues but it already works quite nice (eg. tiles are cached but never renewed).

that's really cool - thanks for contributing to the "snippets" article - I hope we can add more examples and screen shots to grow this and make this really useful.
