Digital soil mapping: strategy for data pre-processing. Soil maps have a great deal of ambiguity regarding the exact location of transition zones, which leads pedologists to disagree about the proper delineation of soil classes at those locations. The aim... ... Repository: BDPA Publication year: 2012
The Use of GIS and Digital Elevation Model in Digital Soil Mapping: a case study from São Paulo, Brazil. Abstract: This paper applied pedological mapping in an experimental center of APTA-Frutas in Jundia´ý, S?ao Paulo, Brazil, using morphometric parameters and GIS tools. The aim of this work was to obta... ... Repository: BDPA Publication year: 2008
Digital soil fertility mapping of the North, Northwest and Serrana state of Rio de Janeiro. The development of methods in digital soil mapping has been an activity that's growing substantially in recent decades. The DSM is quickly evolving from the research stage to map production at various... ... Repository: BDPA Publication year: 2010
Digital soil mapping at Parque Estadual da Mata Seca, Minas Gerais state, Brazil: applying regression tree to predict soil classes. The use of Digital Soil Mapping (DSM) to predict soil classes is an important issue to decrease costs and subjectivity of soil maps. The main objective of this study was to use DSM to produce soil map... ... Repository: BDPA Publication year: 2010
Applying Conditional Latin Hypercube (cLHS) for selecting soil sampling location for Digital Soil Mapping at Parque Estadual da Mata Seca, MG, Brazil. The use of the Conditional Latin Hypercube (cLHS) to select soil samples location to be used in the prediction of soil properties as soil organic carbon seems to be an important tool to decrease costs... ...

Digital soilscape mapping of tropical hillslope areas by neural networks. Geomorphometric variables are applied in digital soil mapping because of their strong correlation with the disposition and distribution of pedological components of the landscapes. In this research, t... ... Repository: BDPA Publication year: 2011
Modelling and digital soil mapping of the organic carbon stock in the topsoil (0-10 cm) of Rio de Janeiro State, Brazil. A soil database with 431 soil profiles of Rio de Janeiro State was used in the scope of a research project entitled "Quantifying the magnitude, spatial distribution and organic carbon in soils of Rio... ...

Digital Soil Mapping Using Multispectral Modeling with Landsat Time Series Cloud Computing Based. Abstract: Geotechnologies allow natural resources to be surveyed more quickly and cheaply than traditional methods. This paper aimed to produce a digital soil map (DSM) based on Landsat time series da... ... Repository: BDPA Publication year: 2021
No silver bullet for digital soil mapping: country-specific soil organic carbon estimates across Latin America. Country-specific soil organic carbon (SOC) estimates are the baseline for the Global SOC Map of the Global Soil Partnership (GSOCmap-GSP). This endeavor is key to explaining the uncertainty of global... ... Repository: BDPA Publication year: 2018
