Computational system for geostatistical analysis. Author(s): VENDRUSCULO, L. G.; MAGALHÃES, P. S. G.; VIEIRA, S. R.; CARVALHO, J. R. P. de ABSTRACT: Geostatistics identifies the spatial structure of variables representing several phenomena and its use is becoming more intense in agricultural activities. This paper describes a computer pr... ... Repository: BDPA Publication year: 2004
Geostatistical Analysis of NDVI in rotational and continuous grazing pastures. Author(s): GREGO, C. R.; MANJOLIN, R. C.; NOGUEIRA, S. F.; RODRIGUES, C. A. G.; SILVA, G. B. S. da; CONCEIÇÃO, M. P. C.; HERLING, V. R. Livestock rearing is an important economical activity in Brazil, and its production is affected by pasture management methods. In this context, the use of geostatistics to analyze the spatial variabil... ... Repository: BDPA Publication year: 2016
Spectral reflectance of satellite images using geostatistics methods to estimate growth and cotton yield. Author(s): BRANDAO, Z. N.; GREGO, C. R.; INAMASU, R. Y.; JORGE, L. A. de C. The objective of this study was the spatial identification of the NDVI index and cotton yield distributions through different crop phenological stages using geostatistical methods in Goiás state, Braz... ...

Detrending non stationary data for geostatistical applications. Author(s): VIEIRA, S. R.; CARVALHO, J. R. P. de; CEDDIA, M. C.; PAZ GONZÁLEZ The use of geostatistics requires at least that the intrinsic hypothesis be satisfied. The presence of a trend in the data invalidates this hypothesis. One of the ways of solving this problem is by su... ... Repository: BDPA Publication year: 2010
Exploring spatial patterns of GCM projection bias via model based geostatistics. Author(s): MAIA, A. de H. N.; HAMADA, E.; GONDIM, R. S. General Circulation Models (GCMs) are numerical models developed to represent physical processes in the atmosphere, ocean, cryosphere and land surface. They constitute the most advanced tool currently... ... Repository: BDPA Publication year: 2013
Geostatistical analysis of crop yield maps in a long term no tillage system. Author(s): GUEDES FILHO, O.; VIEIRA, S. R.; CHIBA, M. K.; GREGO, C. R. It is known, for a long time, that crop yields are not uniform at the field. In some places, it is possible to distinguish sites with both low and high yields even within the same area. This work aime... ... Repository: BDPA Publication year: 2010
Geostatistics as a basis to the CMLS pesticide simulation modes with validation in soil columns. Author(s): NICOLELLA, G.; PEREZ FILHO, A.; SOUZA, M. D. de; FERRACINI, V. L. The use of simulation models is probably the most efficient means for predicting the behavior of pesticides in the soil-plant-water system. The CMLS (Chemical Movement in Layered Soils) simulation mod... ... Repository: BDPA Publication year: 2005
Improving coffee yield interpolation in the presence of outliers using multivariate geostatistics and satellite data. Author(s): SILVA, C. de O. F.; GREGO, C. R.; MANZIONE, R. L.; OLIVEIRA, S. R. de M. the objective of this study was to evaluate the use of remotely sensed data as auxiliary variables in the block cokriging (BCOK) modeling of coffee yield characterized by the presence of outliers. Repository: BDPA Publication year: 2024
Dissimilarity of parameterized maps generated in geostatistics and the assumption of an automatic software model in precision agriculture. Author(s): MALVEZI, K. E. D.; SIBALDELLI, R. N. R.; PEREIRA NETO, O. C.; MORAES, L. A. C.; SAAB, O. J. G. A.; MOREIRA, A. Repository: BDPA Publication year: 2020
Evaluation of statistical and geostatistical models of difgital soil properties mapping in tropical mountain regions. Author(s): CARVALHO JUNIOR, W. de; CHAGAS, C. da S.; LAGACHERIE, P.; CALDERANO FILHO, B.; BHERING, S. B. As propriedades dos solos têm grande impacto sobre aspectos econômicos e ambientais da produção agropecuária. As relações quantitativas entre as propriedades dos solos e os fatores que condicionam sua... ... Repository: BDPA Publication year: 2014
