I had planned on using an xml file to store the URL's that should be polled for data, so adding regions should be trivial in that respect. The biggest problem I can think of that would get in the way is if the different agencies format the advisories differently. That has the potential to become a coding nightmare if we have to parse 15 different advisory formats. I obviously do want full world coverage though. > Date: Tue, 10 Nov 2009 09:46:16 +0100 > From: Oliver Schroeder > Subject: Re: [Flightgear-devel] Hurricane simulator development > To: FlightGear developers discussions > > Message-ID: <200911100946.16198.f...@o-schroeder.de> > Content-Type: text/plain; charset="iso-8859-15" > > Hi. > > We could build our own server, which collects the data from all > sources and make it available to flightgear clients.

This sounds like a great idea to me. The biggest issue here would be who is going to host the service and will that service be reliable enough? If you do decide to tackle this then I would ask that you actually parse the advisories for the needed data, then serve only the necessary details to the FlightGear clients. This would minimize the bandwidth load on the server as well as make my job a lot easier since my code will only have to deal with a standardized format that contains only data I care about. You and I would need to get together to hammer out the format. The storm advisories (at least from the NHC) are released using 5 filenames per region. Each region's file ends with the numbers 1-5. Each number corresponds to a storm. For example, all the advisories for Hurricane Ida were released under the filename MIATCANT1. Each advisory has an advisory number in it which I will need to do internal sanity checking. I would also like a stanza to indicate the filename of the advisory as that's how I'll logically reference the individual storms. There is no rush on getting the server done as I've literally just started this, and it's going to take quite some time for me to hammer out the initial code and get it tested. The more I dig into this, the more parts I find I'll have to interface with. Right now I'm climbing the steep learning curve to get a grip on the different functions in the sim and how I'll have to relate to them. The URL to get the advisories from NHC is: http://www.nhc.noaa.gov/ftp/pub/forecasts/aviation/ We'll need to invest some time into finding equivalent advisory servers for the other centers. So, here is what I'd need, comma separated with values pulled from the example advisory data below (this is not to say this is the format I want, just the stanzas I'd ne

Hi. We could build our own server, which collects the data from all sources and make it available to flightgear clients. I see two benefits of this approach: 1) we have all sources, and 2) we don't abuse the public services As I don't see any complications in fetching the data, I would volunteer to write the server.

[Flightgear-devel] Hurricane simulator development
This message is to announce my intentions to develop a hurricane simulation system for FlightGear. I've done only preliminary work on locating data resources, and in exploring the source code to get a grasp of the different systems I'll have to interface with in FlightGear. This will be my first time working on a project as large as FlightGear. My plans are to have a command line option to enable hurricane simulation much the same as the existing real weather fetch mode does. When enabled the program will fetch data from NOAA's Tropical Cyclone ICAO (Aviation) Advisory server. This is a simple text advisory that won't be too difficult to parse. A sample of this advisory is at the end of this message. I have conversed with the administrators of that server via email and they appear to have no problem with the idea. I will write some form of protection to avoid all the FlightGear clients storming their servers for new advisories at the NXT MSG times. The new module will use this data to, by default, render a "best guess" simulation of any active hurricanes based on the advisories. There is always a queue of the last 5 storms each in the Atlantic and Pacific regions available there so any of those 10 storms could be selected by the user to be simulated. I would also plan on adding a dialog under the environment menu to allow the user to select any of those storms or to define their own hurricane parameters for simulation. To be sure, this will be a very rough simulation of a hurricane, especially early on. I want to make sure that there is as little performance overhead as possible for the model. I essentially want to have the model maintain a table of conditions, based on storm strength and movement, present at any given region relative to the storm center, and feed those conditions to the existing weather modeling structures based on the current user's position. This would basically be a table of prebuilt models of the different levels of storm strength that would be selected and positioned based on the advisory data. I plan to build models for depressions, storms, and category 1-5 hurricanes. I'm hoping the existing weather modeling code can handle wind speeds in the 150kt+ range! What I would like to know is who would be a good developer for me to look to for guidance with integrating this module into the existing framework. Also, I'm not a meteorologist so I'm hoping to have some mentors to go to if I have questions about the best way to model various aspects and area's within a hurricane. Does anyone have any comments, ideas, or criticisms of this idea before I really start investing a lot of effort into it? Any individuals I should talk to before investing a lot of my time into it?
