2016-07-05 09:45:58 - QTVLM Bug Report
How do all

Further to discussions in the RTW chat Odyss pointed out that QT had some annoying bars across the screen. I had initially put it down to a shortage of memory on my computer and the bars being nothing but a drawing issue - but on closer inspection it seems to be affecting the routing - screen shot Odyss posted in chat

Version 5.3.7

The problem occurs when using saildocs and Brainaids gribs

Update- Issue is also occurring in 5.3.5
Update - from Kipper All, just tracked down the Qt bug. If the grib grid resolution is 1 degree or greater, the problem occurs. Of the resolution is less than 1 degree, it goes. I've just reprocessed the Brainaid grib down to 0.5

Hello,
From where is this grib coming from? Is it something generated by SOL somehow?

It is the Brainaid grib and the SailDocs gribs :)

The grib displays fine if the standard interpolation is used.

So it's either inherent to the SOL interpolation formula, or it's a problem in our implementation of it.

Im not a tachie but Kippers point that making the grib denser (to under 0.5)and the problem being resolved seems to suggest its the way QT is handling less dense files.

The conversion is a process few of us (me included!) can do!!

Thank you for looking at this

Kipper has changed the 10:26 grib file into something usefull for QtVlm.
I'll see if I can persuade him to do this to the following updates, until the guys at QT has solved the problem.
They ARE alerted :-)

Another solution is to change the settings in ADVACED fro SOL to Standard.

It looks like there is a transposition error. The stripes are displaced down the page by exactly one grid resolution (2.148 degrees).

Mad Max by Balloon 2026 - Across the Outback


Mad Max Rockatansky doesn’t get to go in a balloon in any of the Legends of the Wasteland, and the Wasteland is not necessarily the Outback of Australia, but Mel Gibson and film director George Miller indubitably are… of Australia, and ballooning as reconnaissance is a main feature of the Mad Max spin-off video game, so here goes: 1500nm in a balloon from somewhere on the edge of the Outback, Goondiwindi, to cross a finish line at Fitzroy Crossing, somewhere on the edge of the Outback!
