[Xastir] Local offline maps

[Dale Seaburg]

Background:  I am a newbie to xastir.  I have played with it a bit  
from time to time, but my interest has been in the HamHUD as far as  
APRS is concerned.

Local needs:  We are to have a SET in May in our county (Brown  
county, Texas).  I would like to set up an xastir station at the  
EOC.  One of the local ham club members is familiar with UI-View, but  
he says the maps are really bad.  I like the tigermaps in xastir  
because of the road detail and general clarity.  BUT, unless you have  
a lot of cached views for the areas needed previously established, it  
requires an internet connection.  For the SET we should have Internet  
service, assuming we can get EOC permission (access codes).  But,  
what about in a real emergency...?

Questions:	1) what is the best way to either cache views of a center  
point with say a 25 to 50 mile radius and various zoom scales (1 in =  
2mi, 1 in = 5 mi, etc.)?
			2) are there any good offline maps of a given area that have some  
reasonable zoom ability?

Boiling these two down to the final question:
			3) what is the best approach to not having internet service, but  
still have good maps?
