abstract = "Information about the land cover and land use of a region are
fundamental in studies such as mapping of deforestation and forest
degradation. Quantifying and monitoring woody cover distribution
in semiarid regions is challenging, due to their scattered
distribution. Data mining has been widely used in remote sensing
data for information extraction of spectral and temporal data in
the analysis of change detection. The main objective of this study
was to characterize the land cover and land use over 2000-2010
time period for the Brazilian Caatinga seasonal biome using a
temporal NDVI series and Geographic Object-Based Image Analysis.
For each of the target years was obtained NDVI images derived from
MODIS (MOD13Q1, at 250 m spatial and 16 day temporal scale) sensor
during the dry season to predict wood cover in the municipality of
Buriti dos Montes, in the state of Piau{\'{\i}}, Northeast
region of Brazil (H13V09 tile). The images were automatically
pre-processed and in the GEOBIA approach was performed image
segmentation, spatial and spectral attribute extraction and
labelled according to the following legend: Tree Cover (TC) and
Cropland/Grass (CG), to obtain a classification using the decision
tree supervised algorithm. Our results showed that approach using
GEOBIA presented Kappa Index of 0.58 and Global Accuracy (GA) of
0.81% and showed better accuracy for the Tree Cover. Finally, we
recommend new studies using a higher spatial resolution data, as
well as the addition of other parameters strongly related to
vegetation of semiarid regions.",
