“…In the study 4 (Arruda et al, 2013), five RAs (total 12 km²) were selected by grouping, in order to extrapolate soil-landscape relationships to an area of 120 km², thus, obtaining 77.5% GA and 0.74 K. In the study 5 (Villela, 2013), a conventional detailed soil survey was performed in an area of 80 km 2 , which was used as RA to extend the map using DSM techniques to an area of 730 km 2 with scale reduction and legend simplification. Four DSM charts were built, from which two were trained by models based on the conceptual model of the pedologist for the area of study, and two were trained by models based on the statistical analyses of information on the RA.…”

“…The obtained results were compared with the findings of studies previously conducted in Brazil by using RA for DSM (ten Caten et al, 2011;Arruda et al, 2013Arruda et al, , 2016Villela, 2013;Silva et al, 2016). Scientific articles were searched using the Scielo, Scopus, and Web of Science platforms, based on a study by ten Caten et al (2012).…”

“…Como o relevo da região é bastante movimentado, essa variável torna-se importante para explicar a variabilidade de pH na região. Moore et al (1993) A declividade tem sido considerada um dos mais importantes fatores abióticos que controlam o processo pedogenético em uma escala local ou regional (Arruda et al, 2013). Para uma melhor compreensão das causas da variabilidade do solo, é importante o conhecimento do relevo.…”

“…ANNs can be applied in many areas, like soil digital mapping based on soil-landscape relationships (Arruda et al, 2013), classification of degradation levels of pastures (Chagas et al, 2009), rainfall erosivity (Moreira et al, 2006, estimation of reference evapotranspiration through air temperature data (Alves Sobrinho et al, 2011), modeling of soil penetration resistance (Santos et al, 2012) or even identification and classification of soybean cultivars by planting region (Galão et al, 2011).…”
