multitemporal data obtained in the near infrared spectral bands
disclosed anomalies in the transition vegetation between Amazonian
rain forest and Cerrado, Brazilian tropical savannah (Mato Grosso
State, Brasil). The visual interpretation of TM/LANDSAT images
showed the spatial, spectral and temporal characteristics of these
anomalies. Through digital analysis carried out in two test areas,
it was no possible to improve the anomaly patterns definition.
Spectral parameters were more consistent than vegetation indices
in the differentiation between anomalies and the surrounding
vegetation. The first observation of this occurrence was done in
panchromatic aerial photographs (obtained in 1967), and lately, in
the near infrared spectral bands of the satellite images. This
fact allowed to infer that the existence of these anomalies is
relacioned with the regeneration of the vegetation in these
specific areas and demonstrated the application of this spectral
bands similar works.",
