hello! can anyone help me. Please! i really purposely registered coz you might help me with my problem. The aim in our project is to get chlorophyll a content (mg/L) out of the Landsat ETM+ image using band algorithms in ENVI. I have already made the image atmospherically corrected which now, have reflectance pixel values. i tried then some known band algorithms afterwards as stated in some researches. however, i am kinda confused if the results were already the chlorophyll content. Is there "in-between" process before getting the real chlorophyll a values? how to convert the reflectances to chlorophyll content? Am i in the right direction? Your replies to this inquiry will really be much appreciated. thanks in advance!
