                         (PAI)and the normalised difference vegetation index (NDVI), were 
                         obtained by an empirical method using Landsat images. In the first 
                         stage, linear, logarithmic and non-linear models were developed 
                         and tested. Bush and tree specimens were considered in the study, 
                         so that most of the individuals that contribute to the spectral 
                         answer detected by satellite images were included. In a second 
                         stage, orbital parameters (NDVI)were used to map the PAI, which, 
                         by its turn, was used to map the phytomass, based on the 
                         relationship of this phytomass in function of PAI. The residues 
                         between measurements and estimates based on NDVI varied from 1 to 
                         45, while the residues of total dry weight of phytomass per ha 
                         obtained by mapping and by dendrometrical equations varied from 4 
                         to 78, with a large tendency of 257 in area of open Caatinga, due 
                         to the contribution of the herbaceous stratum in NDVI.",
