This is around 1 percent of the lakes that can be assessed using Landsat imagery.
Spectral sensitivity increases as spatial resolution decreases.
Unfortunately, the number of lakes that can be studied with each of the resolutions also decreases sharply. The practical number of lakes is actually lower, because some lakes have complex shapes or include islands, and have therefore a higher probability of containing pixels contaminated by land. Of these, only 17 were used in our analysis, because lakes smaller than 160 ha in surface area were excluded. All rights reserved.
