Description
Calculate terrain metrics on elevation RasterLayer
Usage
1
CalculateTerrainMetric(elev, size, metric)
Arguments
elev
RasterLayer, elevation data raster
size
numeric, dimensions of analysis window (nrow and ncol). Must be
odd number. When size == 0, it is internally converted to size == 1 which
is necessary for the metric to be calculated (and not just revert to the
'elev' layer. This was done to allow an optimization procedure to include
a "sigma = 0", even though that would be identical to size == 1.
metric
character, vector containing one of these options: tpi, tri,
roughness (see Details)
Details
metrics based on examples given in terrain() in 'raster' package
Value
RasterLayer
