AutoRA: an algorithm to automatically delineate reference areas: a case study to map soil classes in Bahia, Brazil. Author(s): RODRIGUES, H.; CEDDIA, M. B.; VASQUES, G. M.; GRUNWALD, S.; BABAEIAN, E.; VILLELA, A. L. O. 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
Sample design effects on soil unit prediction with machine: randomness, uncertainty, and majority map. Author(s): CARVALHO JUNIOR, W. de; PEREIRA, N. R.; FERNANDES FILHO, E. I.; CALDERANO FILHO, B.; PINHEIRO, H. S. K.; CHAGAS, C. da S.; BHERING, S. B.; PEREIRA, V. R.; LAWALL, S. 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... ...

AutoRA: an innovative algorithm for automatic delineation of reference areas in support of smart soil sampling and digital soil twins. Author(s): RODRIGUES, H.; CEDDIA, M. B.; VASQUES, G. M.; GRUNWALD, S.; BABAEIAN, E. Digital Soil Mapping (DSM) enhances the delivery of soil information but typically requires costly and extensive field data to develop accurate soil prediction models. The Reference Area (RA) approach... ... Repository: BDPA Publication year: 2025
Use of airborne radar images and machine learning algorithms to map soil clay, silt, and sand contents in remote areas under the Amazon rainforest. Author(s): FERREIRA, A. C. de S.; CEDDIA, M. B.; COSTA, E. M.; PINHEIRO, E. F. M.; NASCIMENTO, M. M. do; VASQUES, G. M. Soil texture has a great influence on the physical-hydric and chemical behavior of soils. In the Amazon regions, due to the presence of dense forest cover and limited access to roads, carrying out sur... ... Repository: BDPA Publication year: 2022
Could airborne geophysical data be used to improve predictive modeling of agronomic soil properties in tropical hillslope area? Author(s): BASTOS, B. P.; PINHEIRO, H. S. K.; FERREIRA, F. J. F.; CARVALHO JUNIOR, W. de; ANJOS, L. H. C. dos Airborne geophysical data (AGD) have great potential to represent soil-forming factors. Because of that, the objective of this study was to evaluate the importance of AGD in predicting soil attributes... ... Repository: BDPA Publication year: 2023
