Lab 5: M2.2 Interpolation

Lab 5: M2.2 Interpolation

Our labs on Surfaces continued on with Lab 5 with Interpolation with Thiessen Polygons, IDW, and Spline. 

Thiessen Polygons - as the name suggests - creates polygons between the sampling points.

IDW (Inverse Distance Weighting) - a DEM that gives weight to its nearest neighbors but can be "spotty".

Spline - DEM that smooths the differences between points.
