Bathymetry data spanning British Columbia's coast.
data(bcBathymetry)
Three-element list: x
= vector of horizontal grid line
locations, y
= vector of vertical grid line locations, z
= (x
by y
) matrix containing water depths measured in
meters. Positive values indicate distance below sea level and
negative values above it.
The functions 'graphics::contour'
and 'grDevices::contourLines'
expect data in this format.
Function convCP
converts the output from 'grDevices::contourLines'
into a PolySet.
