Geographic extent

[evetion]

Something that we can apply the correct crstrait on from GeoInterface. We can discuss here how intersections on such an extent would look like.

This object will need implementations of all the predicates.

We can set up special cyclic dimensions that move any values to -180 : 180 cycle in the constructor. Then bounds in high-low order are wrapping around.

So predicates will have to check the bounds order and have a branch for both.

X=Cycle{-180,180}(170, -150) would do it and be generic.

[evetion]

That looks nice! However, can we also generically implement crstrait (i.e. dispatch) on it? Any Extent with a Cycle as one of its dims?

[rafaqz]

Yeah we may still need a wrapper type, but this at least makes the predicates generic to any cyclic dimension
