You have a little homework. You'll have to snag it using a correctly
built .geofile. The image alone is
here:http://www.met.ie/weathermaps/latest_radar.gif
You then have to get the coordinates of the image corners and try to
determine if it's projected in a polar stereographic form, as so many of
my colleagues like to make the result more correct for viewing. I've
not done the math on the rotation parameters to make that work. I
suspect it'll be an html get in the .geo.

On another note, there's work afoot to make Ordinance Survey data free
for Amateur Radio and public service applications, or, if the solicitors
keep getting in the way, at least to make the geodata inexpensive. They
already have a service for cellphones that's about 5 pound GB per year
(don't know if that's going directly to OS or the cellular carrier) and
hoping that, for things like APRS (which the head of OS hadn't heard of
but found very interesting) the data can be available this calendar year.
<status=change subject='Open Geospatial Consortium musings'>
See? Letting me get out of town to the Open Geospatial Consortium
meetings is useful to the hobby, too! On another note, I'm trying to
hack together an Open Geospatial Consortium Open Location Server using
APRS-IS data. Seems OGC OLS folks never thought of the potential for
using any medium besides cellphones.
OGC demonstrations already use APRS-IS data to demonstrate the Sensor
Observation Service, both for vehicle tracking and snagging the weather
data out and using it as sensor streams. Interesting stuff. Because
it's REST- and XML-based, it's not nearly as compact as APRS, but useful
in the paradigm of the XML revolution that's been sweeping the net...

Morning,
I wonder if one of you guys could give me a pointer as to how I could
grab the image in
http://www.met.ie/latest/rainfall_radar.asp
and attempt to make it a transparent overlay for xastir?
Any thoughts appreciated.
