If the study of drought and tree canopies were required, which portion of the electromagnetic spectrum would provide most pertinent information for Remote Sensing techniques?
Homework Answers
As in remote sensing, we use false color composite for the visualization of vegetation or trees canopy. In this false color composite, we use near infrared band in the red color gun, red band in green color gun and blue in blue color gun for spatial visualization of area of interest. In the above mention configuration, clear water appears dark bluish (higher green band reflectance), while turbid water appears cyan(high red reflectance due to sediments). Bare soils, roads and buildings appears in the shades of yellow and gray and vegetation appears to be bright red in visuals. So, for trees canopy near infrared wave between 0.7-1.3 micrometer is used. As we know vegetation plays a crucial in determining whether an area is strucked by drought recently or not. So, in a conclusive way near infrared band and Short wave infrared(swir) wave plays a prominent role in remote sensing of drought assessment.

The men of the Tuskegee study were egregiously deceived. They were uninformed by having information withheld, and intentionally misinformed--in other words, lied to. Today there are rules regarding informed consent, whereby subjects of research and experimentation are given full disclosure in order to willingly and voluntarily agree to participate in studies and experiments. But consider this: In some cases, even though prospective subjects are given full and complete information, they do not understand the information they are being given. For...

Case: Charles was put in charge of a research study which required 40 participants who were between the ages of 55-75, had a diagnosis of diabetes, and a recent (less than 4 weeks) diagnosis of diabetic neuropathy. The treatment required a short duration from diagnosis because it required certain anatomical structures still be intact. Currently, 39 participants had agreed to the trial and met all the criteria. Two of the participants were diagnosed with diabetic neuropathy 3 weeks and 6...
