In two small and isolated wetlands located at the interface of Atlantic Forest Brazilian savanna (Cerrado) in São Paulo State, Brazil, we employed a pixel-based supervised classification approach using combination panchromatic multispectral bands obtained from Landsat 2, 5, 7, CBERS-04A satellites (ranging 80 to 2 m/pixel). addition, acquired DJI Phantom 4 Pro UAV-RGB images twelve different pe...

In this study we analysed the dynamics of deforestation and burnings during the dry seasons from 2003 to 2008 in the Uruçuí-Una Ecological Station (UUES) and its buffer zone, located in the Cerrado biome of the southwest of Piauí, a Brazil's State, based on images from the orbital sensors CCD/CBERS-2 and TM/Landsat-5. Two dates from each of the years were interpreted and analysed: one in the mi...

Given the low accuracy of the traditional remote sensing image processing software when orthorectifying satellite images that cover mountainous areas, and in order to make a full use of mutually compatible and complementary characteristics of the remote sensing image processing software PCI-RPC (Rational Polynomial Coefficients) and ArcGIS-Spline, this study puts forward a new operational and e...

Abstract. Cloud free images are useful for applications where the user is more interested in the visual identification of variability of a phenomenon than in the actual values. The presence of clouds and their shadows hinder the visual interpretation in these applications. Median values in data sets are a better representation of the true value than the average when the data set is contaminated...

By 2050, half of the net increase in world’s population is expected to reside sub-Saharan Africa (SSA), driving high urbanization rates and drastic land cover changes. However, data-scarce environment SSA limits our understanding urban dynamics region. In this context, Earth Observation (EO) an opportunity gather accurate up-to-date spatial information on extents. During last decade, adoption o...

The Brazilian National Institute for Space Research (INPE) is operating the Brazilian Environmental Data Collection System that currently amounts to a user community of around 100 organizations andmore than 700 data collection platforms installed in Brazil. This system uses the SCD-1, SCD-2, and CBERS-2 low Earth orbit satellites to accomplish the data collection services. The main system appli...
