Land use management and control of deforestation in mega cities became an important problem due to pressure of urban sprawl. In addition, green areas and fountain-heads must be preserved in these cities, for the sake of living quality. For the purpose of monitoring deforestation and non-legal use of lands, this paper presents an approach to detect changes on the remaining areas of Atlantic Forest...
The performance of image classification usually depends on the quality of labelled datasets to be used as training samples. In the context of remote sensing, the acquisition of ground-truth data can be a difficult and expensive task because it depends on the comprehensive surveys over the area of interest while the labelling task must be performed by experienced professionals. On the other hand, algorithms...
This article attempts to characterize urban land use patterns by variograms parameters from multispectral high spatial resolution satellite images. The variography is used to characterize variability and to characterize a land use urban pattern. Dataset compiled from Salvador, Bahia, Brazil, consists in single QuickBird satellite scene, geometrically corrected, obtained on August 2nd, 2005. Four land...
