I am interested to map small water bodies in a desert . I used Gond method described in an article entitled "An Assessment of Surface Water Detection Methods for Water Resource Management in the Nigerien Sahel ". The threshold values used does not map water bodies full according to their boundaries /contours. Is there any way in GEE as magic wand tool in Photoshop or Versatile Wand Tool in ImageJ. Can I select water in output image using Versatile Wand Tool plugin in ImageJ. can ImageJ be used along with GEE for said purpose . I have share code please let me know if there is problem in using it .
