The figure 4 shows the area with example to Early Stage in 
Forest Conservation . It's possible observes the existence of few 
species.

The Figure 5 shows the area vegetation classified as Forest 
Conservation Internship in Secondary. There is a clear 
difference in the texture of the vegetation and a more diversity 
species.

After identification of classes for field work were generated 
graphics reflectance curves for each class. The results are shown 
in Figure 7.

Figure 7. Reflectance of different vegetation cover 
All classes considered in the study had different spectral 
responses, allowing to separate the targets. The location of the 
sample and the influence of topography are important factors to 
define and differentiate each class. 
The classes F1, F2, F3 and pasture showed different spectral 
responses, considering the average of the samples. By 
analyzing separately each class is it possible see the difference 
between the samples in front of the north position or the south. 
Some classes Fl and F2 showed similar responses and were 
eliminated during the analysis. Some classes had interference 
from shadows, because it is a region with great variation in 
topography and floristic diversity. 
This initial analysis identified the different responses of each 
coverage that will generate a more detailed mapping of each 
vegetation type. The classification will be made in next stage 
using object-oriented classification. 
4. CONCLUSIONS 
The vegetation is the target of many strategies for conservation 
in Brazil. The use of a hyperspectral sensor is intended to 
support the demands for use and land cover classification, of the 
different stages of conservation of vegetation in the areas of 
interest. In future steps will be carried out further analysis to 
identify new classes, as well the as comparison with data 
collected in the new field. The remote sensing Hyperspectral 
has been shown promise for the analysis the vegetation.
