Well done, that was a missing feature. I'm a solo ocean sailor, kitesurfer and snowkiter, dreaming about combining sailing and snowkiting in Norway at some point.
Well, regarding the tides, I agree with @timber2 on most points. Here's my list:
- meters instead of ft
- coefficients would be nice
- especially in the English Channel (east of Dover), the tides can produce some very weird pattern with double high tides in a cycle due to strange interference. See also this paper. These cases make a visualization very important, instead of just raw High and Low values.
- some ressources that come into mind regarding tide levels:
-- dmi.dk - click on "Vandstand" - this shows a nice "sloshing" of the tide wave in the North Sea
-- myocean & earthcube.org for general ocean & earth data
-- German tide forecasts in Northern and Baltic Sea bsh.de - nice to see the difference between astronomical tide and ocean model prediction, including an error estimate.
- last, for all the whitewater enthusiasts, I know the "tide" on the rivers are of utmost importance! This is probably a bigger project, to keep you guys busy, but would be great to see as well. I guess also to see correlation of accumulated rain and flooding.
Well, keep up the good work!
