Estimation of soil moisture in the root-zone from remote sensing data. Author(s): BEZERRA, B. G.; SANTOS, C. A. C. dos; SILVA, B. B. da; PEREZ-MARIN, A. M.; BEZERRA, M. V. C.; BEZERRA, J. R. C.; RAO, T. V. R. Repository: BDPA Publication year: 2013
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
Assessment of sugarcane harvesting residue effects on soil spectral behavior. Author(s): DEMATTÊ, J. A. M.; TERRA, F. da S.; OTTO, R.; TOMA, R. S.; PEREIRA, L. H.; NASCIMENTO, A. F. do; BORTOLETTO, M. A. M. When the harvesting of sugarcane involves a mechanized process, plant residues remain on the soil surface, which makes proximal and remote sensing difficult to monitor. This study aimed to evaluate, u... ... Repository: BDPA Publication year: 2016
A comparative study of techniques for modeling the spatiotemporal distribution of heat and moisture fluxes at different agroecosystems in Brazil. Author(s): TEIXEIRA, A. H. de C.; HERNANDEZ, F. B. T.; LOPES, H. L.; SCHERER-WARREN, M; BASSOI, L. H. As a result, this chapter is structured as follows: following the introduction, the study region, datasets, and the steps for modeling are described; one of the first comparisons between SAFER and SEB... ...

Comparative assessment of atmospheric correction of Landsat imagery using Modtran and dark object subtraction. Author(s): LOEBMANN, D. G. dos S. W.; VICENTE, L. E.; DE PAULA, S. C.; VICTORIA, D. de C.; ANDRADE, R. G.; SILVA, R. F. B. DA; AGNESE, M. L. Remote sensing by spectral imaging of the Earth's surface can be widely used, but only when the atmospheric influence is nullified and the data are reduced to surface reflectance units. The atmospheri... ... Repository: BDPA Publication year: 2012
