swissalt: Elevation in Switzerland

Description

Data required for plotting a Switzerland map with elevation.

Usage

data(swissalt)

Format

This data set contains three R objects. 'alt.mat' is a 192 by 115 matrix giving the elevation at the grid points defined by 'lon.vec' and 'lat.vec'.

Examples

# NOT RUN {
data(swissalt)

layout(matrix(c(1,2), 1), width = c(3.5,1))
mar <- rep(0, 4)
op <- par(mar = mar)
breaks <- seq(0, 2000, by = 250)
image(lon.vec, lat.vec, alt.mat, col = terrain.colors(length(breaks) - 1),
      xaxt = "n", yaxt = "n", bty = "n", xlab = "", ylab = "", xlim =
c(480, 840), ylim = c(58, 300))
