In the process of doing this implementation, I will end setting up a

Grand. Does etc include WFS? In any case, I'd love to get a look at
the details. Layering various applications interchanging data through
a mixture of lightweight and heavyweight standards and storing them in
spatially enabled databases seems to be a very logical direction to
move in.
Sure we can do WFS/GML as well. Although, you can also quickly and
easily serve up a WFS (or WMS) from these GeoDatabases using something
like GeoServer http://geoserver.org/display/GEOS/Welcome
I can also provide features from the same server providing WMS for
radar. We've been doing that for some time now.
A direction to think about down the road for both weather data and
velocity/bearing data are the OGC efforts towards Observations and
Measurements schemas and Sensor Observation Services.
Absolutely, but I generally stay away from these heavyweight standards
until they are actually implemented widely. In the short term, I am
concentrating on lightweight standards that people actually use ...
like KML, GeoRSS, GeoJSON.
SOS isn't that heavyweight, and we're working on it in my lab, and in a
collective project. Want pointers to some cookbooks? Start here but
feel free to browse around the site:
http://www.oostethys.org/downloads/sos-cookbook-perl
Just FYI, my current project involves tracking dozens of moving assets
(cars, airplanes, bicycles, humans etc) at the Burning Man art
festival in Nevada later this summer. We are integrating the
positions from APRS (and normal gps logs, nmea, gpx etc) into an
existing geodatabase of the camps, art installations etc.
Should be cool!
So whatever is reusable after I am done insofar as APRS and Xastir is
concerned will get setup as a pluggable django app. I.e. you could
grab the code and run it on top of your PostGIS or MySQL db which is
fed with data from xastir.
We're working toward getting weather obs and radar, possibly weather
model forecasts, into SOS over the next couple of months.
