I would like to re-activate this thread.
Many users of the German community "complain" about the largely reduced tidal information in OpenCPN
compared to the ones originally shipped with (W)XTide.
There are also some newer TCD files available - see: XTide Downloads
And Jean Pierre (and maybe others) has done some "update" on the HARMONIC files for adding more stations and correcting some data.
So here is my proposal:
Let's start to build
- a new HARMONIC file with worldwide coverage which is as much up-to-date as possible
- split this file, or extract subregions from this file e.g. America, Europe, Asia etc.
And an additional question to the programmers out there:
How to convert a HARMONIC.tcd file to the needed text file format for OpenCPN?
And there seems to be some kind of tool "tcd-utils" being available on the website - see: XTide Downloads
Let me know what you think about it.
