interpolate.edges: Function to interpolate edge nodes.

In coffeemuggler/RCHILD: Functions for flexible use of the landscape evolution model CHILD

Description

This function identifies the outer boundaries of the modelled surface (boundary flags 1 or 2). These nodes are typically set to zero elevation. The function searches for the closest non-zero node and uses its elevation.

Usage

interpolate.edges(dataset)

Arguments

dataset

(S4-object) CHILD model run output data set.

Value

An S4-object with output data of a CHILD model run, but with interpolated z-values of nodes of the surface boundary.

Examples

# load example data set
data(hillslope1b)

# display original surface
display.surface(hillslope1b, timestep = 20, type = "wireframe", theta = 90)

# interpolate edges
hillslope1bi <- interpolate.edges(hillslope1b)

# display interpolated surface to check the differences
display.surface(hillslope1bi, timestep = 20, type = "wireframe", theta = 90)
