abstract = "Brazilian Savanna, also known as Cerrado, is one of the most
important biomes in world in terms of biodiversity. Mapping
Cerrado is an important task, considering that deforestation
reached almost half of its original area. Two classification
systems are currently used to map Cerrado Land Cover and reference
maps are available on the scale of 1:250.000. Thus, the aim of
this study is to discuss the challenges regarding the automatic
classification of Cerrado land cover using the reference maps of
1:250.000 produced by Brazilian Institute of Geography and
Statistics (IBGE). Three protected Cerrado areas were used in this
study, Bras{\'{\i}}lia National Park (DF), Emas National Park
(GO) and Chapada das Mesas National Park (MA). Images from the
Landsat-8 satellite, acquired in the dry and wet seasons, were
used in the classification. Images were segmented and classified
according to Brazilian vegetation classification system.
Classification was performed through the random forest algorithm.
The classification results pointed out an overall accuracy of
84.4%. The main source of classification error was transition
areas among the vegetation formations. Due to the map scale, some
areas close to the edges are not distinguished with precision and
may be incorrectly classified. The use of high resolution images
can improve the classification results in the vegetation
boundaries. Another notable problem is that the Brazilian
vegetation classification system does not separate Gallery Forests
from other classes although the segmentation has distinguished
these segments quite well.",
