Isochrones missing after 105°E
Post by iconPost by Silver Wings | 2020-12-02 | 14:46:23

Hi there,
Sorry if the topic has already been addressed, I could not find it.
After the 105°E, the isochrones are not displayed south of my route.
Also, if I set the destination point somewhere south, the optimal route is missing.
Only if I disable gates the isochornes are displayed, but it is not the purpose...
Thanks for help
Manël, Aubenas, France

Try to zoom out. The picture is rendered partially on the highest zoom levels, so the far ens is missing.

Thanks for answer
Unfortunately, even with 1% zoom, the line is broken south of a route that I cannot choose.

There is a kind of "unreachable area" south from ca. 46°S after Australian gate.

Oh, I see what you mean.

The track does not want to go South?

It's a quirk of the router. It does not like going around far away obstructions (the ice limit in this case)

It will fix itself when we get closer. That's the price for the performance and does not really matter 99% of the time (once you know what's going on)

Try moving your origin around 110E or even 85E.

Similar behavior can be observed around land and even around high-pressure systems.
