Lab 5 - Spatial Interpolation


Post your output to your blog and write a paragraph discussion about recent vs. normal rainfall for LA County, and which interpolation technique you believe is best for the data and why. I chose to use spline and IDW interpolation techniques because they provided smoother maps of the data, and while kriging may provide a better method of modeling it didn’t present a good visual interpretation. IDW seems to provide the best results (for example, spline modeling gives negative rainfall which is clearly impossible), and this makes sense because the amount of rainfall should depend on the rainfall in a neighboring cell.
