    sir i have a doubt in line no 41, these you have used Boolean which will return all pixels having water seasonality more than equals 5 months as 1, and less than as 0; but we here had to make a mask which will return a mask all pixels less than 5 months as 1 and pemanent water body as 0;
    will the code should use lt instead of gte, please rply;
    ALSO i would like to thank you for uploading such valuable videos.

    Sir after connecting pixels I didn't get the correct result...it doesn't cover maximum flooded area....so in what basis I should select clustered pix threshold which cover the most flooded areas.....pls suggest me...

      The connectedPixelCount function is zoom dependent, so don't judge the result based on what you see in the code editor. Export the results and then check. Start with the values given in the script and if reduce the threshold.

      Thanku sir for clarifying

    The threshold of the slope that you added, is it to hide the low water areas?

      Water cannot accumulate on steep areas. The threshold is to find flat areas.

      @@MuntadaAhlussunna This is using the HydroSHEDS DEM to compute slope. See the code.

      The video quality ia fine. RUclips adjusts quality automatically based on your bandwidth. You can go to setting and manually set it to 1080p to watch it in HD.
