Spatial Interpolation
In a study by Fast, Jollineau, and Reynolds (2013), spatial interpolation was used to estimate the value of soil moisture at unsampled field locations based on measurements taken from sampled locations (the red box in the figure below highlights some areas in which soil moisture measurements were taken) at the Stratus Vineyards in Niagara-on-the-Lake, Ontario, Canada. As demonstrated in the figure below, from this interpolation, the authors were able to determine and map the spatial variability of soil moisture for the entire vineyard. This information can then be used by vineyard owners for improved management and crop yield.
