Re: Free Routing Software. qtVlm

I installed qtVlm on my linux machine and it works fine. I also installed 3.4 on my mac osx but I can't get the toolbar buttons to show up. Anyone know how?

Re: Free Routing Software. qtVlm

You can show/hide sub-toolbars by right-clicking on the toolbar itself. There is a known problem from time to time with this at startup under mac which I hope will be fixed in the next one.

If just the buttons are missing it's probably because you didn't install qtVlm correctly. Check that you do have an "img" directory which contains all the icons.

Re: Free Routing Software. qtVlm

I want to create a routing for an Atlantic crossing from Salvador, Brasil to Mindel, Sao Vincente (Cape Verde). This should be about a 15 day crossing.

But I have only 8 days in my grib, so QtVLM can't contine after 2/3rds of the trip

Any way around this?

Re: Free Routing Software. qtVlm

You can download a saildocs grib, 16 days. There is an option for that in qtVlm (select a zone, right-click, choose email to saildocs. If you are not using a default mailer uncheck the option in qtVlm settings and just copy/paste the body of the message in a mail to query@saildocs.com, subject whatever you want but not empty).

Re: Free Routing Software. qtVlm

Thanks Maitai. Next issue: I'd like to take the equatorial current into account. I can get a current grib file from http://www.svsarana.com/oscar/index.php. This file opens fine in OpenCPN, but not in QtVLM.

Sample file: http://journeyman.se/hd/MidAtlanticCurrents.grb

Re: Free Routing Software. qtVlm

That grib is not supported by qtVlm 3.4.0. It will be in the next release...

Re: Free Routing Software. qtVlm

Would someone mind explaining in a bit more detail how to get a free grib that has current - specifically the gulf stream - that can be viewed and used by qtvlm in routing. I have been reading forums for hours and am newer at this. The programs you guys have put together are fantastic.

Re: Free Routing Software. qtVlm

I've just added RTOFS (saildocs gulfstream currents) to the list of supported grib in qtVlm. I will be in available in version 3.4.1 due soon.

You can get free currents gribs for Atlantic at Navimail (Mercator currents gribs are free). To do that either download and install free navimail software, or send a mail to navimail@meteo.fr with "req" as subject and for instance in the body:

@mto@reqt@grib@
A 1
Z -38.000 20.000 124.000 46.000
M 0.5
D 10
P courant
E 168 192 216 240
C bzip2
s 2.1.3
@mto@reqt@fin@

There are many other places where you can find free currents gribs compatible with qtVlm...

Re: Free Routing Software. qtVlm

I find it strange that you can copy routes from Opencpn and paste into qtVlm, and also do the reverse, however we have difficulty doing that with plugins!!!
There are some hooks and connections that are needed internally as external calls.

Re: Free Routing Software. qtVlm

Rick,

I agree 100% with you. There is a basic need for internally as external calls, that can make the plugin work under windows.

Re: Free Routing Software. qtVlm

Having read all through the thread and tried the Linux download, make and install instructions I am still stuck. The installation process even succeeded in locking up the machine (no mouse cursor movement, no keyboard effect) and I had to power down the machine.

Any chance of a deb installation file?

Idiens...
Refer to QtVlm - VlmWiki Don't worry the text is in French, the package is just as any other package and the PPA is just as any other PPA...

Re: Free Routing Software. qtVlm

Hi Pavel,
Even that overstretches my Linux inabilities. I get it installed but on starting qtVlm I get an error message:-

p, li { white-space: pre-wrap; } Impossible d'écrire dans le répertoire de qtVlm
Changez les permissions de ce répertoire ou
réinstallew qtVlm autre part


On pressing OK, it shows a progress bar, then a small hopeful window opens, looking good, then it vanishes. Click the icon again, same story.
