Spatio-temporal modeling of data imputation for daily rainfall series in homogeneous zones. Author(s): CARVALHO, J. R. P. de; NAKAI, A. M.; MONTEIRO, J. E. B. A. Spatio-temporal modelling is an area of increasing importance in which models and methods have often been developed to deal with specific applications. In this study, a spatio-temporal model was used... ... Repository: BDPA Publication year: 2016
Saptiotemporal dynamics of agricultural production diversity in Sergipe and Alagoas between 1999-2018. Author(s): SILVA, M. A. S. da; FABIO R. DE MOURA; DOMPIERI, M. H. G.; LEONARDO N. MATOS; FLAVIO EMANUEL DE OLIVEIRA SANTOS This work aims to investigate this agricultural diversity in the states of Alagoas and Sergipe, Brazil, by generating agricultural diversity surfaces for these indices proposed by [3]. A more precise... ... Repository: BDPA Publication year: 2023
Model for multiple imputation to estimate daily rainfall data and filling of faults. Author(s): CARVALHO, J. R. P. de; MONTEIRO, J. E. B. de A.; NAKAI, A. M.; ASSAD, E. D. Modeling by multiple enchained imputation is an area of growing importance. However, its models and methods are frequently developed for specific applications. In this study the model for multiple imp... ... Repository: BDPA Publication year: 2017

Soil carbon stock and particle size fractions in the Central Amazon predicted from remotely sensed relief, multispectral and radar data. Author(s): CEDDIA, M. B.; GOMES, A. S.; VASQUES, G. M.; PINHEIRO, E. F. M. Soils from the remote areas of the Amazon Rainforest in Brazil are poorly mapped due to the presence of dense forest and lack of access routes. The use of covariates derived from multispectral and rad... ... Repository: BDPA Publication year: 2017
Field proximal soil sensor fusion for improving high-resolution soil property maps. Author(s): VASQUES, G. de M.; RODRIGUES, H. M.; COELHO, M. R.; BACA, J. F. M.; DART, R. de O.; OLIVEIRA, R. P. de; TEIXEIRA, W. G.; CEDDIA, M. B. Mapping soil properties, using geostatistical methods in support of precision agriculture and related activities, requires a large number of samples. To reduce soil sampling and measurement time and c... ... Repository: BDPA Publication year: 2020
