The images are georeferenced to the Illinois State Plane, Eastern Zone, using the NAD83 2011 horizontal datum. Color InfraRed (CIR) imagery allows users to &quot;see&quot; the electromagnetic spectrum beyond the visible range. It does this by using the visible spectrum (red, green, blue) and combining it with the Near InfraRed (NIR) spectrum. CIR imagery is useful for determining the health of vegetation, which show up in various shades of red. It can also be helpful in identifying features like water, paved surfaces or non-vegetated areas, which appear black or grey respectively. The data set is tiled for dissemination into many separate tiles, each of which is 2500 feet on a side.</span>
