[Xastir] Weather map question

[EarlNeedham via Kubuntu]

I like to use the WMSradar map when the weather get rough out here, but I have 
a slight problem with it -- I don't see any landmarks, towns, etc.  I see 
other APRS stations on the map, and unless I can see one that I recognize, I 
have no way of knowing where the cells are.  Is there a way to add, say, 
Tiger maps at a low level to the weather maps?

Thanks,
Earl
