North Dublin, Ireland - a photo on Flickriver

            The first image above is a normalized difference vegetation index (NDVI) image of north Dublin, Ireland. The lush Lambay island can clearly be seen, as well as the Rogerstown Estuary. The image below is a reconstructed RGB image. Comparing the two images, we can see the benefit of incorporating IR data into the NDVI image - it's much easier to see the delineations between land and ocean, and even between separate land types. The different types of fields are very easy to differentiate in the NDVI image.
