Hi Vos My Name is Arnaud Kouekam from Cameroon PhD Student at University of Douala. I'm working on shoreline change of Cameroon coast from 1986 to present by using coastsat. Now I have a serious problem 🤣 concerning tidal correction l have already tried all your recommandations in github but nothing. I don't Know how to have a tidal data of my study area by using FES 2014. I'm blocked in this part (# load the measured tide data). Please help me.

here the coordinate of my study area polygon = [[[9.088158938288675, 4.029667592089233], [9.092557761073099, 4.031358555658276], [9.073932501673685, 4.044436648659763], [9.071271750330911, 4.042274818042125], [9.071271750330911, 4.042274818042125]]]; thank you for your availability

I sent you the tides via emails as the file was too big for github. Once you have the tide timeseries (1984-2022 every 5 minutes) the coastsat code should be able to find the closest tide point to every image and apply tidal correction with a given slope.
