WebReflectance increases (and absorption decreases) dramatically towards near infrared (NIR), and has distinct water absorption features both in NIR and shortwave infrared (SWIR) regions. The largest differences between coniferous needles and broad (flat) leaves are in transmittance, and in SWIR reflectance. WebRemote sensing is the science and art of identifying, observing, and measuring an object without coming into direct contact with it. This involves the detection and measurement …
