3 Wavelengths
True color images are made by combining
red, blue and green light.
Combined together, these visible bands of light make up all the colors in the rainbow
and all of Landsat’s true color images.
Landsat also captures light that we can’t see.
That type of light can reveal some incredible things
when you look at a false color image.
Like the difference between types of plants,
how healthy those planets are,
healthy coral reefs and even dead coral reefs,
fire-tracking, ocean pollution...
The possibilities are nearly endless!
