[Xastir] Radar

[David Flood]

Hello All,

Here's a summary of where Radar was last April.  I doubt that the NWS has made it any easier or simpler to use their information since then.

William,

I've been giving this some thought since you sent this.

You are correct that the included Maps link for Xastir radar are broken.  During the last few redesigns of the NWS websites and available datasets the data needed to work with Xastir became unobtainium.

That being said, it is nice that some sort of information (note I didn't say data) is being provided once again.  However, there doesn't appear to be an easy way to use the files from the link you provided since they don't have any coordinates associated with them.  They're just pictures of the current radar returns.  So, download methods aside, someone would have to view each and every one and figure out the approximate zoom factor that matches up with the GIF and then do the programming to only display the GIF when you're near that zoom factor.

Assuming that someone did that, then there's the question of downloading the pictures.  Since they're constantly changing, there probably would have to be a completely different program written that gives the user the list of available radar choices and then every X minutes retrieves the appropriate choices to someplace local where Xastir can then read it.  Sort of a local WX Image Server...

So, until someone finds the ATU's to do all of the above or the NWS starts providing the actual data behind the pictures, there doesn't appear to be an easy way to get semi-live radar displays back in Xastir.  Or at least that's my take from the Peanut Gallery...

I would like to get Radar image overlays working in Xastir again...it's been a long time since I last had it working.

It seems that the overlays are available https://www.weather.gov/jetstream/ridge_download

How should I configure these as maps in Xastir to be used?

BTW, the links to radar maps here https://xastir.org/index.php/Xastir_Maps appear to be broken.

Thanks for pointers!
