Did-g added an toggled eye to the route list and fixed some route position issues.

Re: Weather Routing

All..
Eventually also I have tried Weather routing. I'll give a OCPN training for ocean cruisers so I better learn this plugin.
I'm on Win10 O 486 WR_pi ver.1.12.1 built today. Only grib as source.

I get "Land failed" halfway a route from the Azores to Gibraltar when CM93 is active. Using only GSHHG computing went smooth.
Is that a known problem?

Re: Weather Routing

Hakan, with your issue in mind, I downloaded a new 16 day 2.0 degree wind grib for the atlantic. Using 4.8.6 and most recent weather_routing_pi and an old config I had made from provincetown to lizard, set to grib time (at the beginning of the grib file) and checked grib and climatology "most likely" in case the grib time ran out, and then ran it, with CM93 charts turned on. This seemed to complete OK.


That doesn't mean there isn't an issue, I just did not find it.


But perhaps it is some other problem which causes it to fail with CM93 charts on? Because I've never seen this kind of chart dependence, in fact I don't believe wx_routing cares what charts are used, it is using GSHHG and requires the High Resolution download from inside Chartdownloader now. Make sure you have that. Particularly if you have detect land checked.



Try unchecking detect land and leaving CM93 on.
Move your start and finish points out into clear sea, sometimes islands and complicated landmasses with the long 12hour intervals make it not complete.

Try shortening the time interval if you think the landmasses are a problem.


Increase max diverted too.


Gille was having similar trouble which was sorted out here

Re: Weather Routing

Rick..
Yes strange things happen.

With land check off it was no problem also with active CM93.
With land check on and hidden CM93 chart no problem. (Yes GSHHG is full res.)
Later, after completed calculation, it was working also with viewed CM93 charts. So for the moment this issue is closed. I can't reproduce it anymore.
BTW I can't get Climatology_pi to work properly but has to revert on this later.

Thanks
Håkan

Re: Weather Routing

Here is another trial using an Empty Chart Group with Climatology turned off showing just the high res background outline that wx_routing uses.
The grib file is not long enough and fails with the notice
"Grib; Polar;no data;Land;Failed"


The problem is no grib info.


The second screenshot is showing the different colored climatology isochrones with CM93 charts at the end that are using Climatology 30 yr average data.

Re: Weather Routing

Strange, thing. Glad it is working now.

Re Climatology:

BTW I can't get Climatology_pi to work properly but has to revert on this later.


Is it the scaling of the wind roses? See first image FAQ How do I set the Wind Rose settings so that they work right? Set the two settings somewhere around Size:100 and Spacing:100 or Size:125 and Spacing:60. These sometimes get messed up when Climatology is updated from a very older version.



Or is it not working with wx_routing or something?
