Seagrasses are submerged ecosystems, in shallow estuaries. They have flowers, long and narrow leaves, green most of the time. They are very similar to wheat fields.
During the interpretation of RGB photos in the visible spectrum, some elements / characteristics / materials can be difficult to differentiate, but this does not happen when we go to the INFRARED SPECTRUM.
We can generate a precise classification, based on the spectral signature and the physical and visual inspection, as well as the ability to calculate the classification area, since we can obtain the type of material for each pixel.
