[Xastir] Fwd: [ge0rg/aprsdroid] New offline map link (#211)

[David Ranch]

Hello Everyone,

Thought I'd also pass on a note from the APRSDroid group where there 
seems to be a new online/offline map tool that might be useful for Xastir.

Just came across this site and it quickly and easily creates custom 
areas of offline maps that are compatible with the offline version and 
it can

make relatively large area at a time. You might add a link to this site 
o the offline web page.
