    It will be better is the code can calculate the surface water area over time not just the NDWI mean values

      Hi. How that can be made? You mean doing a classification?

    • @geographerpakistani

      @adilos12345 Thank you for your suggestion! I'll explore incorporating surface water area calculations into future iterations of the analysis. Your feedback is greatly appreciated, and I'm committed to improving the depth and accuracy of our analysis.

      @@KraivKris Yes, exactly. To calculate the surface water area over time, we can perform a classification using the Normalized Difference Water Index (NDWI) to identify water bodies in the satellite imagery. By setting a threshold on the NDWI values, we can classify pixels as water or non-water, thus estimating the surface water area. This approach allows us to track changes in surface water over the specified time period. Let me know if you need further clarification!

    i performed the Code on my study area but ,mine cant identify the water body

    • @geographerpakistani
      @geographerpakistani  8 หลายเดือนก่อน

      If the code is not identifying water bodies in your study area, it might be due to several reasons, including incorrect threshold values for NDWI, cloud cover, or differences in the spectral characteristics of water in your area compared to the default settings in the code. Here are some steps you can take to troubleshoot and improve the water body identification:Adjust NDWI Threshold,Check Cloud Cover,Refine Masking.

    • @geographerpakistani
      @geographerpakistani  8 หลายเดือนก่อน

      ​@@rajeshgm6294 Thank you for your interest! Yes, you can indeed monitor groundwater levels using satellite data. While the GLDAS dataset (ee.ImageCollection("NASA/GLDAS/V022/CLSM/G025/DA1D")) provides valuable information, it's important to note that its resolution is relatively coarse at 27830 meters. This may not be ideal for detailed analysis, especially in regions with complex hydrological dynamics. That is why I don't prefer it .
