I am working on a research work whereas we want to measure the forest resistance and resilience from the Annual mean NDVI images of last 30 years. Please help me to provide any methods to do the processes with necessary references.
Which set imagery did you use please? Precision, accurancy, résolution..
You can compare the différent patch colour to have a idea of the esistance and resilience.You can also show the seasonnal, variation and the proximity of water ressources as explaination factors.
Herve Parmentier I have used landsat 5 TM imaginary, resolution 30 m. I need to know the dry years resistance and resilience data from 1990 to 2020 mainly. Please suggest me any specific formulae or paper please if you can.
You may take the long term (30 yr) mean of annual mean NDVI and can compare responses (increasing, decreasing or stable trend) of each pixel in correspondence to climatic trend in the same pixel in 30 yr time scale. You may find several papers related to this approach like one share by Manoj Kumar sir as above.
