abstract = "The Cerrado Biome has suffered intense degradation in the last
decades. The State of Goi{\'a}s, a component of the biome, had
its vegetation affected by degradations motivated by agriculture
and pasture, with an emphasis on the economic aspect. The use of
satellite data associated with Geographic Information Systems has
positive experiences in the monitoring of deforestation, and for
this reason it is adopted in national research institutions. From
this, this work aims to identify areas in the municipality of
S{\~a}o Miguel do Araguaia-GO that have undergone deforestation
between 2002 and 2011 by means of linear regression in NDVI
temporal images of the TM sensor on board the Landsat-5 satellite.
The adopted method applies a linear regression in the temporal
images of NDVI, extracting the slope of each value of the pixel in
relation to the posterior year. Three slope values were defined:
5, 10 and 15 degrees, representing the degrees of sensitivity of
the vegetation cover change. It was verified that the value of 5º
obtained greater sensitivity of alteration of the vegetation cover
of low to high tree density. In the validation, this method
obtained an overall precision of 83.13%, 72.18%, 50.9%, 47.62%
respectively between 2008 and 2011 done in the value of 5º of
slope. In the comparison with another mapping method, such as the
Brazilian Biome Deforestation Monitoring Project (PMDBBS), it was
verified that the overall accuracy was 66.67% and the Kappa index
of 0.3, being therefore suitable for the detection of tree
changes. The proposal may be relevant to accompany the
transformations in a biome like the Cerrado, which has a great
diversity of forest cover.",
