Análise de técnicas de amostragem geoestatística

Abstract

Em geoestatística o método de amostragem é um fator que influencia no resultado dos mapas de krigagem. Utilizar a amostragem aleatória ou sistemática, apesar de comumente resultar em ajuste de semivariograma com o mesmo modelo, causa diferenças entre seus parâmetros. Comparando as duas técnicas de amostragem foi possível observar os resultados dos mapas na mesma região e determinar que o uso da amostragem sistemática com auxílio de submalhas auxilia no controle de outliers espaciais e é o ideal para detectar todos os níveis de dependência espacial.
