[OAM-talk] The once and future OpenAerialMap

[John Robert Peterson]

This is awesome -- it's looking like somthing really impressive may
come out of this.

I've been following the discussion, and I'm a great believer in
emergant properties. I think that using physical proximity to decide
what to cashe would be a mistake. I think that cashing based on
regularity of use/use of similar tiles/time since last use etc would
work better.

For example, the 2013 games in canada mentioned, when that goes up,
many people from all over the world are going to be viewing the data,
irrispective of thier physical localities. You would not want those
tiles to be dropped from a server in south africa simply because a
tile of the middle of the sahara was closer.

I'd say connect every user to a server that's close to them (in terms
of network latancy) and let the statistics determin what gets cashed
where. Though, if you need a tie breaker, by all means fall back
location.

And when you build the sytem to connect users to servers, be sure to
take into account server load.
