otidalplan_pi - planning with tidal current harmonics

Some work has been done to make ETA calculations possible using tidal current harmonics.

https://github.com/Rasbats/otidalpla...eases/tag/v0.1

This plugin uses an idea from Nobeltec. Tidal currents are attached to a route and then the route is calculated.

DR calculations are also possible.

Windows only installer at present.

In the code the calculations are made for three minute time intervals. If you have two very short routes and slow speed the calculation will fail, with a warning.

The template for a lot of this came from the Weather Routing plugin. Thanks Sean.

Instructions for use will follow.

Mike

Only for use in narrow channels so far! I have an issue with the maximum distance for searching for currents.

A fix for open waters like the English Channel.

A guide has been added to the GitHub release.

The pdf is too large to post here.

Had to make a small correction to allow the plugin to compile on Linux:

https://github.com/Rasbats/otidalpla...eases/tag/v0.3

Installers for Windows and Ubuntu 18.04.3 (AMD64) are available.
