[Feature Request] tide level

[iammyr]

First of all this is amazing! Thank you so much :)
I just thought it would be awesome to have tide levels showing as well, given their relation to the moon phases. Thanks again

It is an interesting feature; we should add it.

My questions:

1. what should be used as input? Location name? The same as for weather?
2. What should be output? Current tide level? tide level forecast?
3. Is it for the one-line output only? Or should be added as an additional line to the v2 view (v2.wttr.in)?

@chubin

1. For input I sugest to keep it simple and keep the same as for weather.
2. For ouput I sugest tide forecast for the current day on the nearest port with ( Low tide (AM time / AM level : PM time : PM level) High tide (AM time / AM level : PM time : PM level) )
3. For one-line output sure, for the v2 view I’am not sure because if you check weather inland you have no intrest for tide.

Yeah, what's the expected output if I (implicitly) ask tide for Ulaanbaatar? Is there an arbitrary 'inland/shore' line to draw?

[Kefedric]

@iago-lito I think (as previously mentioned) that tide should only get result of a nearby harbor.

I imagine you could make a querry base on locations gps coordinates and compare it to a list of harbor coordinates (with tide data)
if your location is in the range of a harbor then you display the tide info.
and if there are multiple then we must think of a funcitons wich finds the nearest.

[iago-lito]

Okay. Not sure what data is available in wttr backend about harbors and shores, though. Does any city have a boolean tag explicitly stating "I'm a harbor" ?

Alternately, if the coasts polygons lines are available, any city has gps coordinates so its distance to shore can be compared to an arbitrary threshold (say, 30km?) to decide whether or not to display the tide information. This will also work for cities that happen to be close from the shore, but not close to a harbor.

@iago-lito
Sorry but I have no knowledge on the backend data.
What I know, is where I live, tide data are available by harbor.

[chubin]

I think we have two options here:

1. The tide-level must be queried explicitly (%-notation, or {{tide}}), for one-line output;
2. For the locations where tide-level makes sense (locations on shore), it could be displayed automatically in some views (like v2).

The first one would be much more simple to implement, and probably would satisfy most users.

For the one-line mode, perhaps we need to support additional arguments,
or do you think al users would like to have the same output format
Low tide (AM time / AM level : PM time : PM level) High tide (AM time / AM level : PM time : PM level)
?

[Kefedric]

@chubin Indeed one-line mode should be enough for most users.

And for the argument maybe one for low tide display and another for low tide ?
