2018 Lake County Color InfraRed (CIR) - SW Quarter

This three inch pixel resolution color infrared aerial photography was flown between March 20, 2018 to March 26, 2018. The files are provided in JPEG2000, an open format supported by most GIS and CAD software packages. Its intended usage for viewing is 1" = 100. The photography has been orthorectified to meet National Map Accuracy Standards for its capture scale. The images are georeferenced to the Illinois State Plane, Eastern Zone, using the NAD83 2011 horizontal datum. Color InfraRed (CIR) imagery allows users to "see" 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.
