Use of Multispectral Imaging in the Evaluation of Burnings and Forest Fires in Krahôlandia Indigenous Land (2003-2014)

Abstract: Human actions change the natural occurrences of wildfire. The indigenous communities, during their time of occupation of the Cerrado, probably utilized fire to manipulate the landscape and its resources. In this study, we mapped and analyzed the spatial distribution of burned areas of the Kraholândia Indigenous Land, from 2003 to 2014, using Remote Sensing resources and GIS tools. During the assessed period, the total burned area extended across 1,516,873 ha, representing 4.94 times the sum of Kraholândia Indi… Show more

“…This is mainly because the supervised method ultimately deals with many classification algorithms, while the unsupervised method employs only a few of them, which usually have lower accuracy than the supervised methods. Several studies used supervised parametric classification algorithms such as maximum likelihood (ML) (11.3%) [53, 173,210,297,[314][315][316][317][318] and Mahalanobis distance (MD) (3.8%) [319] (Figure 8b).…”

“…Ao analisar o mapa da vegetação e as queimadas por meio da técnica de sensoriamento remoto na Reserva Indígena Krahô, Tocantins, Bitencourt et al (2005) verificaram que práticas de queima executadas pela tribo que vive no local não prejudicaram o Cerrado. Isso sugere que o efeito não prejudicial em relação a esse ambiente pode estar relacionado ao uso controlado do fogo, que atua como forma preventiva de evitar a ocorrência de incêndios (Oliveira et al, 2015).…”
