Correlation of LANDSAT bands 4 and 5, based on the input data provided for the exercises of the lecture "Remote sensing image processing with open source GIS". A link to the data will be provided as soon as it is downloadable.
R Code:
library(rgdal)
# load maps
band.blue <- readGDAL('sub_L71195024_02420050623_B20.TIF')
band.green <- readGDAL('sub_L71195024_02420050623_B30.TIF')
band.red <- readGDAL('sub_L71195024_02420050623_B40.TIF')
band.nir <- readGDAL('sub_L71195024_02420050623_B50.TIF')
bands <- data.frame(band.2=band.blue@data$band1,
band.3=band.green@data$band1,
band.4=band.red@data$band1,band.5=band.nir@data$band1)
png('landsat_corr.png', width=800, height=800,

plot(bands$band.4, bands$band.5, xlab='Band 4 (red) brightness',
ylab='Band 5 (near infrared) brightness',
