[Xastir] Converting State GIS Maps

[Gerry Creager N5JXS]

Gerry's swamped these days and trying to keep up with E-mail.  If you 
need a quick answer I've now set up a new filter for the keyword 
'Geodesy'.  I'll look at those ASAP morning and evening.  With meetings, 
proposal writing, mesonet site debugging, and bringing up a numerical 
weather prediction computational cluster, I'm not reading much at work 
anymore.
