This study aims to compile a... ... Repository: BDPA Publication year: 2024
Open legacy soil survey data in Brazil: geospatial data quality and how to improve it. Authorship: SAMUEL-ROSA, A.; DALMOLIN, R. S. D.; MOURA-BRUNO, J. M.; TEIXEIRA, W. G.; FILIPPINI ALBA, J. M. Spatial soil data applications require sound geospatial data including coordinates and a coordinate reference system. However, when it comes to legacy soil data we frequently find them to be missing o... ... Repository: BDPA Publication year: 2020

A.; LEPSCH, I.; GRIS, D. J.; ROSIN, N. A.; MOURA-BUENO, J. M. Brazilian soil scientists have recently created a soil data repository using community-built standards and following open data policies in an attempt to address the issues mentioned above. The Free Br... ... Repository: BDPA Publication year: 2018
Dados para aplicações pedométricas em larga escala no Brasil. Authorship: SAMUEL-ROSA, A.; VASQUES, G. de M. Repository: BDPA Publication year: 2017
Spsann - optimization of sample patterns using spatial simulated annealing. Authorship: SAMUEL-ROSA, A.; HEUVELINK, G.; VASQUES, G.; ANJOS, L. Repository: BDPA Publication year: 2015
Identifying and correcting oblique striping in the topodata digital elevation model. Authorship: SAMUEL-ROSA, A.; ANJOS, L. H. C. dos; VASQUES, G. de M.; ANTUNES, M. A. H.; DALMOLIN, R. S. D. The Topodata digital elevation model (DEM) is the best DEM available for digital soil mapping (DSM) in Brazil. However, it is not ready to use. We show that the kriging interpolator used to downscale... ... Repository: BDPA Publication year: 2013
Comparison of methods for organic matter removal applied in Brazilian Ferralsols. Authorship: ROSA, A. S.; PEREIRA, M. G.; ANJOS, L. H. C. dos; DONAGEMMA, G. K.; DALMOLIN, R. S. D. Latossolos podem apresentar dispersão deficiente na análise granulométrica, devido à presença de microagregados de alta estabilidade, contribuindo para superestimar a fração silte. O objetivo desse es... ... Repository: BDPA Publication year: 2009
