Location: Around once, back to work, for a while :-(
1) Yes, wave-height is displayed, more specific the HTSGW parameter: "Significant Height of Combined Wind Waves and Swell". Opencpn 1.3.6 does not display swell, separate from wind waves or any data about wavelength. If you get your grib data from via airmail/sailmail and you have selected the wave paramater with the GFS model, airmail sailmail will merge HTSGW from the WW3 model into the GFS model and you have wind, wind direction, waves in one file. I also select rain, but that is not being shown by opencpn.
2) No, opencpn 1.3.6 does not do weather routing. As for feature requests: Unfortunately the process for selection of feature requests seems to be outside of any public forum and nobody seems to know what is in the pipe for development.
Use of wave data in WX routing is an awfully tricky issue ... under sail, it always seems that one tack is favored over another and vessel polars (a req'd input to do routing) don't typically capture wave effects.
The georeferenced forecast becomes real usefull when combined with a gribfile for the same time.
If the two files agree, and both agrees with your present observations, you have a confirmation of the grib, and can have higher confidence in the intermediate time steps available.
It is also a good tool to study and learn meteorology.
bvimatelot, you have to elaborate a wee bit more, I'm not a mindreader.
Here is a script for linux that automatically creates .kap files for use with OpenCPN. For now, it creates current surface analysis charts for E and W North Atlantic, as well as 48 and 96 hours surface, 500mb and wind/wave forecast charts for the N Atlantic.
Unzip it in a suitable new directory , run the shell script and point OpenCPN's chart manager to this directory.
Dependencies are: wget, libbsb and ImageMagic.
It can easily be expanded/adjusted to other sources.
Strip the .doc before proceeding.
This script should be easy to port to Win......!
- wind, waves, rain, pressure, water temp, air temp
A spot meteogram nice. A 'following the course/time, multi spot' one I would simply LOVE!
I support the suggestion from Barnakiel about a kind of correlation between a route and grib files.
What I would like to get : select for display in the most recent grib file the view which matches the date/time for the active waypoint.
I have search this forum unsuccessfully for this feature.
