Map Generator Required
On this side of the ditch domestic SIGMETS were issued with geographical locations until a couple of weeks ago. It was a great system.
However in the interests of ICAO rather than safety the CAA decreed all SIGMETS must now be in Lat and Long. Now no one knows where the SIGNET applies to without taking time to plot it. How silly is that?

... there is an emerging standard around digital NOTAM which Eurocontrol have been working on for a while.
The tricky thing is to read all the associated human-readable text to work out what they mean. It's not often the list of lat/lon pairs are just drawing a simple polygon. You need to understand the context of the information.
First, each NOTAM has to become available in two forms: the present human-readable, freeform text one, and the computer readable one, which is sufficiently "coded" to allow the computer to convey at least 90% of the message to the humans.
To Captain Nomad's original post:
For SIGMETs, what you are suggesting is straightforward, and I'm sure the developed world will have such presentations within the next few years. The computer-readable SIGMET of the future will have tightly defined coordinates specifying the area, along with level information and codes to denote the nature of the weather phenomena.
Then, we will be able to easily see the SIGMETs on our screens - during both preflight planning and inflight on our MFD screens.
If this can be done for SIGMETs, then it can also be done for airspace areas involving other activity (e.g military operations, survey operations, balloon ascents, etc).
I have noticed that there is now SIGMET charts available from NAIPS and the BoM website. Admittedly the resolution of the image from NAIPS isn't great and because it covers such a large area it will only give you a general idea if it will affect you or not but it is better nothing to give a quick idea of areas covered by a SIGMET.
From the BoM on the new charts:

From the BoM on the new charts:
The Bureau of Meteorology will begin issuing graphical representations of their text SIGMETs on 29 May 2014.
The graphical SIGMET is intended to improve situational awareness. The text SIGMET should continue to be used for official flight planning purposes.
The graphical SIGMET product will be issued every ten minutes plus whenever a text SIGMET is issued.

As I said at the beginning of this thread, "It's time..." So great to see this become a reality!
The Australia wide map with low/high/all levels options is certainly a terrific start. It may get a bit cluttered at times but the instant big picture it provides to help one determine if a closer look/plotting is warranted should really help with quickly forming an overall mental picture.
I wonder if people in high places read PPRuNe after all?
When you live....
Hmmm - great to see I can get it in clear, high def and colour from a website from which I am not allowed to use (BOM) but instead need to look a copy which looks like it was faxed via the moon from the 'official' source (NAIPS).
Still, it is a great improvement so kudos to those who made it happen.

I feel your pain. obstruction/construction NOTAMs are based on ARP with a direction, leaving it up to the operator to determine impact.
With obstruction types of NOTAMS, for the operators who have tailoered RNP procedures in AUS, I convert the ARP distance and bearing to a different NOTAM for each runway end as affected...most of the time it is simply adjusting the DA/MDA.

A picture paints a thousand words...
Isn't it great that we can sort through the SIGMETS with the benefit of a quick-view map now?!
Would still be great to see a similar map function for temporary NOTAM items...
