Description

World topograph data, on a 2-degree grid.

Usage

data(topo2)

source

The data are calculated from the z entry in the topoWorld data, smoothed with matrixSmooth with passes=2, and then subsetted to 2 degrees of latitude and longitude.

Examples

library(oce)
data(topo2)
# Image with default axes
imagep(topo2)
x <- seq(.25, 358.25, 2)
y <- seq(-89.75, 88.25, 2)
# Coastline with sensible axes
contour(x, y, topo2, level=0, drawlabels=FALSE)
