Incomplete Land Cover Classification in Google Earth Engine for Specific Areas

  Kiến thức lập trình

I’m doing a supervised land cover classification on Google Earth Engine (GEE). While the code works for most of my ROIs, it fails to classify the entire area for one specific forest (Forest 21), leaving parts unclassified. Only a portion of the area is classified correctly, while the rest remains unclassified.This is happening for a few of the areas that I need to classify.

  • Verified the geometry of forest21.
  • Checked cloud cover filter to ensure high-quality images are used.
  • Chnaged date ranges.
  • Tried different satellites (landsat 5 and 7)
