Week 5 lab

Rainfall for this season to date is much higher than the season normal in just about every part of LA. I believe that IDW method worked a lot better for the interpolation of this data set than the spline method. The spline method probably did not work very well because there was a larger change from location to location than I initially expected in the data set and spline interpolation works better in data that have less sharp changes. Additionally I think that the number of points I used for the spline interpolation to reference was too many for the density of the data set. IDW worked well because the sample stations were not uniform distances from each other but were still dense enough to create a reasonable estimation.
