I want to calculate deforestation using Landsat 2 images. Right now I am using the raster calculator to generate a NDVI image and then the reclassification or Iso Cluster Unsupervised classification tool. However, since they are old Landsat images, a lot of them have clouds and it messes with the final deforestation image (difference between classified images).
Is there a way I can get rid of the clouds using the same Landsat for different dates in the same year?
What I am thinking is that it may be possible to overlay the rasters and somehow get an optimal raster for the year, using input from different dates.
Does that make sense?
Is there another way?
