Question
The difference between reflectance in this band and two adjacent spectral bands is used to calculate the NDVI and NDWI, indexes used for assessing plant health. For 10 points each:
[10m] Name this spectral sub-range used for environmental remote sensing because its wavelengths are reflected most by plants. This sub-range’s upper wavelength limit is usually set at 1400 or 2500 nanometers.
ANSWER: near-infrared [or NIR or near-IR; prompt on IR or infrared]
[10e] Near-IR absorbance is used by MODIS for atmospheric measurements of this substance. Humidity measures the concentration of this substance.
ANSWER: water vapor [or H2O; accept aqueous vapor]
[10h] This remote sensing program’s satellites receive near-IR light in their fourth and fifth bands. NASA and the USGS jointly oversee this satellite program, whose image data of Earth’s surface has been freely available since 2008.
ANSWER: Landsat program
