[Xastir] Script to cache some maps

[David Ranch]

If the goal is to make tiles available for offline use, I don't 
understand why creating a NEW tile server help us achieve the goal other 
than avoid OpenStreetMap's abuse clause.

To me, I would think that if we come up with an automated way to 
download current OSM tiles *and* then allow individuals to be able to 
upload the rendered tiles to another site for others to consume, that 
would be a good first step.  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?

Other ideas?
