1   Data set

In this lecture, we will perform various spatial analyses using ArcPy.

Add all the layers in the nc_spm_08_grass7_exercise data set.

2   Bilinearly interpolate the profile of a selected stream

In the previous exercise, we took cell values directly from the raster NumPy array. That implies that we only used the center of cells even for those profile vertices that do not intersect with the cells exactly at the center. Let’s fix that using bilinear interpolation.
