See coordinates vector in raster

You can just do

xy <- coordinates(r1)

which gives a 2-column matrix with

lon <- xy[,1]
lat <- xy[,2]

Note that for largish rasters this is a considerable amount of data,
and it's mostly all redundant since you can generate it from the
resolution and extent, so you might need to consider other options.

Cheers, Mike.

Dear all,

Is there any way to access the vector containing the longitude and latitude coordinates of a raster object? For example:


library(raster)
r1 <- raster(nrows=800, ncols=820, xmn=0, xmx=10)

# I am looking for something like this:
r1$lon
r2$lat

Thanks in advance,

Thiago.
