[Xastir] Script to cache some maps

[Skyler Fennell]

I might be wrong but I think the purpose of a tile server is to eliminate main server stress.

A tile server converts shape file data into pretty tiles, so all you need to do is download the raw data, not the images.

Kurt KC9LDHmentioned he downloaded 11GB worth of tiles from Geofabrikbut it's unclear what that all really included.  Was that a large area with all zoom levels?  In many respects, that Geofabrik download service at http://download.geofabrik.de/ seems to be EXACTLY what I'm talking about.  The main differences is that we'd want everything rendered down to png files.  Next, if people can initially download initial tile archives and later, other people could easily update and UPLOAD new tiles, I think this would be a pretty slick solution for Xastir (maybe other APRS clients too).   If people agree with the thought process here, I think we first need to understand what kind of storage capacity we're looking at here and then where can it be stored.  Could these tile archives be stored be the current xastir.org server? To minimize bandwidth issues, maybe downloads can be restricted to specific "trusted" Xastir accounts/passwords/whatever?
