[R-sig-Geo] Import a GeoTIFF file and plot it on a map with lat-long coordinates - RESOLVED

Right, this is actually what I did, following your code. I used the .jpg file to get the projection and applied it to the .tif file.

I should have worked with the .jpg rather than the .tif file to be able to read the projection and explore the function projectRaster(). Now, I just have to fiddle with the graphical parameters so that the y axis is not too far on the left from the image border.

The jpg is likely to be 'lossy', so if you care about the raw data values you probably need to work with the tiff data (unless thats been compressed with a lossy algorithm!).
