[LUG]Re: tide data pointless proc. - get highest-grf / lowest-grf

 

Perhaps moving up to AI might help. Theres a free app called Weka which comes with free online courses and also an app called Moa which can eat time line data and process it as it arrives. I did a course a few years ago and remember it had mechanisms for handling date with time based cycles  and all sorts of goodies for finding and marking outliers and removing them from datasets.. I think you'll find high tides will break records regularly from now on - low tides breaking records probably means a tsunami is on the way!
Cheers cheerily

Hello all

I had a bit of complete relaxation time yesterday and thoughts
flowed...

I saw you could do the lot with "awk" - the unix toolkit awk command /
utility.

"Rough" first output.

Broadly "it's there"; however there are problems where the tide gauge
was mulfunctioning (a tide making 11.something m above Lowest
Astronomical Tide would if it really happened make the news!!!).
Etc.

The horizontal axis is the tide-gauge's sequential 15-minute
data-record increments in a year
(* 365 24 4) ;; 35040

I would help a more sophisticated "data-crawling" program if there
were inclination to make one.
