Issue with slope estimation

[czarnes22]

Hellol Everyone, Hi @kvos
i installed the FES 2004, created output data from 2000 to 2020 (L5, L7, L8), 2 transects. I have a polar coastline so I have only more than 40 satellite images. Its depend of the day/night time in Arctic (polar day). What do You think about this results? Is it measurable? The frequency images of the tides is not similar to your, exampled situation. Thanks for Your answer, hope so to get good tips or something like that.

hi @czarnes22 , I would not do it with less than 100 points. It will be very hard on 40 points. How much do you expect that beach to movehorizontally because of erosion/accretion processes? Maybe if it's relatively stable you have a chance. I would suggest that you extend it to 2024 and also include Landsat 9, that will give you a bit more data. The high latitudes are hard.
