Selecting the Color Bands


About the Color Bands

LIDAR points that have color values will have at least three valid bands of colors (i.e., red, green, and blue) and an optional infrared band. The red, green, blue, and infrared values within the points are measures of the amount of reflected energy within each respective portion of the light spectrum.

The color values can be used to generate colors on the screen by assigning a band to a color component. Two of the most popular examples are true color composites and false color composites. A true color composite is generated by assigning the red, green, and blue bands to the their respective red, green, and blue color values that are displayed on the screen. The result is a "normal" color photograph that is typically seen with the naked eye. A false color composite or a color infrared image is generated by assigning the green, red, and infrared bands to blue, green, and red color values respectively. Objects in a scene will be colored much differently in a false color composite than in a true color composite forming the basis for numerous remote sensing applications and interpretation.

How to Select the Color Bands

Color Band Boxes

1. Open the Properties dialog box by clicking the button on the LP360 toolbar.

2. Click the Symbology tab, then click the RGB Values tab.

3.Click the down arrow on the red, green, or blue boxes.

4. Select a color band to assign to the color value of the respective box.

Tip

  • If a false color or color infrared image results from a true color setup (i.e., red->red,green->green,blue->blue), the LIDAR point's red, green and blue band values were assigned from an image instead of assigning the green, red, and infrared band values. In this case, a true color image can not be generated from the LIDAR points.
