00:00:03.380 --> 00:00:05.330
3 Wavelengths

2
00:00:05.330 --> 00:00:07.800
True color images are made by combining

3
00:00:07.800 --> 00:00:09.980
red, blue and green light.

4
00:00:09.980 --> 00:00:15.260
Combined together, these visible bands of light make up all the colors in the rainbow

5
00:00:15.260 --> 00:00:18.730
and all of Landsat’s true color images.

6
00:00:18.730 --> 00:00:21.960
Landsat also captures light that we can’t see.

7
00:00:21.960 --> 00:00:24.950
That type of light can reveal some incredible things

8
00:00:24.950 --> 00:00:26.770
when you look at a false color image.

9
00:00:26.770 --> 00:00:28.960
Like the difference between types of plants,

10
00:00:28.960 --> 00:00:30.510
how healthy those planets are,

11
00:00:30.510 --> 00:00:33.170
healthy coral reefs and even dead coral reefs,

12
00:00:33.170 --> 00:00:35.500
fire-tracking, ocean pollution...

13
00:00:35.500 --> 00:00:38.450
The possibilities are nearly endless!

14
00:00:38.450 --> 00:00:41.088
