6. CONCLUSIONS
The results of this image analysis demonstrate the possibility of
using these high-resolution satellite data to map bamboo forests,
and also to monitor the phenologic cycles of the dominant
species. The visual interpretation proved to be an adequate
technique in this case, emphasizing that the knowledge of the
ecological aspects of these bamboo formations was of
fundamental importance to understand the patterns mapped on
the image. Nevertheless there are still more detailed studies
needed as far as the dynamics of this forest typology are
concerned, considering the peculiarities observed in this area.
This study is part of a project aiming the analysis of the spatial
and temporal distribution of forests with bamboos of Intervales.
These results evidence the possibilities for the discrimination of
different vegetation classes using digital processing procedures
at these images during further steps of the work, considering the
specific characteristics of this region, referring to climate and
topography and the need of ortho-rectification, a geometric
correction necessary to improve the precision of future maps.
Taking into account the results presented, QuickBird images are
adequate products for mapping and monitoring at a compatible
scale, the possible expansion of these bamboo forests, feeding a
databank on the species of this region and contributing to better
understand this landscape that was recently diagnosed within
the Atlantic Forest domain.
