A plot of fictional correlation between brightness values of two satellite bands. Generated in R and edited with GIMP.
Code:
data <- data.frame(band.4=c(rnorm(500, mean=100, sd=20),
rnorm(500, mean=180, sd=10)),
band.5=c(rnorm(500, mean=180, sd=20),
rnorm(500, mean=100, sd=10)))
# and plot
png('landsat_corr_data.png', width=800, height=800,
pointsize=15)
plot(data$band.4, data$band.5, xlab='Band 4 brightness value',
ylab='Band 5 brightness value',
main='Fictional example of correlation\n between two satellite bands')
dev.off()
