Sky maps bandwidth problem

Asked by JackBassV

In the "future" part of the 0.10.6 article, it said that you'd need a large server and/or bandwidth to enable uploading of the skymap images.

Why not use bittorrent for data transmission? Either built in or just provide a torrent file(s) and let people download it if they want (or need) to. If you split it into northern/southern hemisphere sections, that would take some strain off the system. Not that much though.

This way, you'd just need a Tracker and 1 copy of the Skymap data. No need for massive bandwidth. Don't know how much drive space is required. I'll leave that for you to figure out.

I don't think many people would want ~50 gig of data on their system. I know I don't.

For any given session with the program, only a tiny sub-set of this is needed, so it lends itself better to streaming those parts which are needed. Same problem and solution as google earth... very few people would use it if they had to torrent the whole dataset before they could look at their house. :-)

Having said that, I hope that it would be possible one day if someone was crazy enough to want it. I don't see why not.

The data size makes no difference to me. I've over 3TB of hard drive space and the next system I build will be 6+TB... Talk about overkill.

But given that most PC's have 512GB or less, I suppose I'm one of the odd ones...

Thanks for the reply.
