[Xastir] Transmit Shapefile ?

[William McKeehan]

The group that I work with on most events uses a variety of APRS clients.  We
have UI-View, Xastir, WinAPRS, APRS+SA and AGWTracker. Developing maps (and
getting them e-mailed before the event) is a painful task, especially when the
maps change at the last minute. If I had a way to transmit the maps, then
anyone interested could see them regardless of which APRS client they are
using and without any need to send them via another route before the event.

As far as the assign tactical calls goes, I do use that feature from
time-to-time. I'd really like to see an extension to APRS that would allow
that information to be transmitted as well - I think the NCS station should be
assigning tactical calls and sharing that information with others in the
field.

I've done a bit of playing with Tom's code, thus far, I've encountered a
problem such that if I give the following 3 points
     Latitude   Longitude
     N35.000000 W083.000000
     N34.000000 W084.000000
     N33.000000 W085.000000
I would expect a line from upper right to lower left, but the code generates a
line from upper left to lower right, so there's a problem somewhere.
