Solar Radiation Interpolation

Abstract

Geographic information systems provide different options to analyze and

represent the spatial heterogeneity of solar radiation incident on a certain area. This

chapter presents a description of the main and well-known methods for determining

interpolation surfaces from a data sample. Moreover, using 3D model of the analyzed

area, computer models of spatial analysis are precise techniques to adjust the

results to the variability of surfaces in a geographic area. Both alternatives offer a

great analysis capacity. The selection of a procedure will depend on the objective of

the study and the available information.
