There are three plugins that we know about that use Polars:
Polar files come in a garden variety with several different types of headers, capitalized or not, [twa, TWA, twa/tws, TWA/TWS] some without wind
speeds fully labeled, some with tab delimiters, others with semicolons and in a variety of degrees.
This thread is an effort to sort ingestion of these various Polar files.
Please understand that weather_routing_pi has a certain format that it likes that is native, however Sean has been able to adjust to importing various formats of polar files and provide some messages when it can't be done, to help.
Perhaps this approach can be used in Polar_pi and TackandLay. Also perhaps Polar_pi and TackandLay_pi have some good techiques.
In any event [opinion] I think all of these plugins should support a single
comment format, and be able to import
or ingest some varieties of that.
See these threads
.org - does not seem to be working.
However in the Opencpn
Manual, weather-routing-pi writeup, at the end there is a separate page about Polar Files written to help with polar "ingestion". It might be helpful, but Sean may have some more concrete suggestions.
Please post your comments in this thread.
