read.TIN: Function to read a TIN from a CHILD file set.

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

Description

This function reads the nodes- and z-files from a CHILD model run data returns a matrix with m nodes and their x-y-z-coordinates for a specified set and time step of the model run.

Usage

read.TIN(dataset, timestep)

Arguments

dataset	CHILD object name.
timestep	Time step from which the node data is read.

Details

The resulting data set is no triangulated irregular network (TIN) object. It is similar in structure to the PTS-file but without boundary flags. However, the data set can serve as input data for a raster interpolation (TIN.raster) or external TIN creation (e.g. tri.mesh from package tripack).

Value

A numeric matrix with x-y-z-coordinates of the nodes.

Examples

# load example data set
data(hillslope1)

# read TIN from time step 10 of data set hillslope1
TIN <- read.TIN(hillslope1, timestep = 10)

# show first 5 rows of the dat set
TIN[1:5,]

# display the modelled surface and add TIN nodes
display.surface(hillslope1, timestep = 10, type = "map")
points(TIN[,1], TIN[,2], pch = 4, cex = 0.5)
