Determinación de la dependencia espacial mediante variogramas

Abstract

En este trabajo se realiza una introducción a la geoestadística, centrándose especialmente en el concepto de variograma, estructura que cuantifica la dependencia espacial, y el método de interpolación espacial Kriging. Para ello se exponen las bases teóricas de la dependencia espacial como fundamento para el desarrollo del variograma, incluyendo la concepción experimental pero también teórica del mismo, así como los distintos modelos existentes y razones por las que puede no modelizar correctamente la dependencia espacial. A continuación se presenta la teoría detrás del método de interpolación Kriging, junto con las diferentes variantes del modelo: el ordinario, el universal y el multivariante. Finalmente, se presenta un caso práctico que plasma la utilidad de estos conceptos con el fin de modelar, mediante las librerías gstat y sm de R, la interpolación de los contaminantes SO₂, PM₁₀ y NOₓ en el territorio gallego.
