a previous knowledge of the region to be studied is 
indispensable and that auxiliary methods should be used, such 
the MODIS triplets and fieldwork samples 
The good results do not eliminate the perspective to test the 
model with other spectral indices than NDVI in the remote 
assessment of sediments granulometry. Likewise, it would be 
interesting to test the method for different geographic regions 
with similar environmental characteristics, as well as other 
scales and images at Pantanal.
