This chapter shows how to use different backends to calculate different interpolations.
The project shows a gradient in rainfall, from south to north.
Let’s use different methods for interpolation, all based on vector points.shp

Set cell size to 500
for all analyses.
Then measure variation among methods and correlate it with distance to points:
points.shp
Thus, areas far from points will have less accurate interpolation.
Various methods to draw contour lines [always step= 10] on the stddev raster:
