Spatial Enhancement

 

The map above depicts a spike in the histogram on layer 4 between 12 and 18, showcasing the waterway features. I made band 4 green in order to create a sharp contrast between the water and the vegetation.

The map above shows a small spike in layers 1-4 in the histogram around the pixel value 200, featuring the snow covered ridges of the mountains. I made band 4 red in order to make the snow pop against the mountainous background.

The map above showcases the shallow lake, which became gradually brighter from layer 1 to 4. I made band 3 green as it highlights shallow water the best.
