We illustrate this by developing an algorithm for generating a catena, or more correctly, a digital toposequence from a digital elevation model (DEM).
As DEM is stored in matrix format, we simply
If we designate the current cell [0, 0] as z1, the function below will look for the lowest neighbor for pixel z1 in a DEM.
find_steepest <- function(dem, row_z, col_z)
z1 = dem[row_z, col_z] #elevation،We illustrate this by developing an algorithm for generating a catena, or more correctly, a digital toposequence from a digital elevation model (DEM).
