Where Lewis and Clark finished the rum | I'm not sure of your question - is it a question of what questions to ask vendors or ??? I've used NIR only, NIR coupled with green or red to calculate veg index, Landsat, IKONOS, Quickbird, as well as GreenSeeker and Crop Circle ground based units, so have some experience. Crop Circle has done some correlations between CS and bare soil. For NIR only check out http://www.srvscience.org/Student/chuckster/Infrared/trees.htm for some satellite stuff check out www.umac.org.
If you are looking for crop health, I think you need more than just NIR - see the srvscience link above for an example of why. |
