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
AutoRA: an algorithm to automatically delineate reference areas: a case study to map soil classes in Bahia, Brazil. The reference area (RA) approach has been frequently used in soil surveying and mapping projects, since it allows for reduced costs. However, a crucial point in using this approach is the choice or de... ... Repository: BDPA Publication year: 2025
Legacy data: exploratory analysis to digital soil class mapping. The use of legacy data improve the value of these data and promote the input of new data on the database. Also, reduces the primary data collection and analytical procedures. In MS State, the legacy d... ... Repository: BDPA Publication year: 2022
Digital soil mapping for soil class prediction in a dry forest of Minas Gerais, Brazil. Investment on soil survey has become scarce over the past decades. Digital Soil Mapping (DSM) techniques emerged as an economic alternative to produce soil maps. We applied a classification tree algor... ... Repository: BDPA Publication year: 2015
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. This paper applied pedological mapping in an experimental center of APTA-Frutas in Jundiaí São Paulo, Brazil, using morphometric parameters and GIS tools. The aim of this work was to obtain a prelimin... ... 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
Sample design effects on soil unit prediction with machine: randomness, uncertainty, and majority map. Notwithstanding the importance of soil surveys, advances in digital soil mapping have mainly focused on mapping soil attributes or properties rather than developing digital maps of soil units or soil... ...
