Harmonics tide file
Hi,
I have used the Harmonics tide file that comes bundled with OpenCPN in Expedition and notice a variation in reported data between the 2 platforms - Expedition seems to display different to OpenCPN and expected data for a given date.
Any ideas?

Opencpn same location

Re: Harmonics tide file
That appears to be a bug in Exp supporting the old xtide format.
Have fixed & will post an update today. The values will have minor differences to Opencpn as the tide calculations are different.

Re: Harmonics tide file
Does the current Exp version support the x-tide file as used in OpenCPN - Is in program files (x86) tc data and is called HARMONICS_NO_US . Also tried an older HARMONICS.txt and no go
Trying to get working on another boats install, using 12.1.11 Navionics, and exp sees the file, can check it but doesn`t import Australian tide stations under x-tide. Is weird because works on my installs (which have been upgraded fro a tie where this harmonics file did work)

Yes, Exp supports the tcd format.
You could send the file.

Re: Harmonics tide file
They are essentially the same file. Try opening in notepad etc.
Just delete the .txt extension and copy to the Exp tides data folder.
Although I see Exp isn't reading them. Will investigate.
