Re: opencpn wont read grib

The name unfortunately does not help at all, please either change the extension to .doc and the forum should accept it, or put it on eg. ExpireBox and post a download link here.

Thanks

Pavel

Re: opencpn wont read grib

This is a GRIB version 2 file, which OpenCPN does not currently support (and never did).
Work on this file format support has recently been started as you can see in gribs concatenation and grib version2 so it will hopefully be available in the next release.

Re: opencpn wont read grib

I have exactly the same problem, and came here to post the same thing.
Just as well I looked at the last dozen OpenCPN posts or I woulda got flamed like a marshmellow !

Free In The Sea, I did notice that I could view the detailed gribs (eg. 8k), but not the global ones.

I guess they use the older format for the higher resolution gribs.
(one is attached just for reference).

edit: Hmm... not sure what happened to my attachment. Working PW Grib file is here: https://www.dropbox.com/s/pliqfeuxpw...0.358.grb?dl=0

Re: opencpn wont read grib

thanks everyone for the answers,
and sorry for the delay we just competed our panama canal transit last night, and happily on the pacific side,

perdictawind responded with that they have had similar responses and that they will be bringing they on grib file viwer online at the end of the month,

but I really do love the over lay on opencpn,
I don't know what's changed as we use to use it all the time before I had to reload, I will try a reload of each again with could internet and if nit succeful will have to wait to what perdictawind come up with,

thanks once again for the helpful advice
its priceless when you are cruising in the areas as good help and can be hard to find,
thanks
