Color Images

An example color image

To create a color image 3 of the 7 bands are selected. They are scaled to spread the pixel values more fully over the range 0 to 255, and then each is assigned one of the colors red, green, or blue.

In the following example bands 4,3, and 1 are used.

Band 4: the values 5 to 75 are scale to 0 to 255 and the image is assigned to be red.

Band 3: the values 13 to 45 are scale to 0 to 255 and the image is assigned to be green.

Band 1: the values 46 to 80 are scale to 0 to 255 and the image is assigned to be blue.

All three are combined into a single color image.
