NIR Camera Test

nir_testsI got an exciting new toy yesterday – a digital camera modified to capture near infrared (NIR), in addition to visible light. As I mentioned in a previous post, the combination of NIR and visible light allows for vegetation extraction on a pixel-by-pixel basis, after applying the NDVI formula. See an example of a raw NIR photo I took this morning, compared to the processed NDVI image, here. It’s not perfect, but it shows promise.

As a side note, my example makes use of the TwentyTwenty javascript widget, which makes sliding image overlays extremely easy.
