The Create Color Composite raster function creates a three-band raster from a multiband raster layer in which each band can use an algebraic calculation based on band algebra.
Notes
When defining a band arithmetic algorithm, you can enter a single-line algebraic formula for each expression to create a multiband output. The supported operators are unary, plus (+), minus (-), times (*), and divide (/).
When using a Band ID in an expression, identify the band by prefixing B or b to the band number.
A common band combination used for dual-polarized synthetic aperture radar (SAR) in linear units is VV for red, VH for green, and VV/VH for blue. If the input data is in decibels, the band combination should be VV for red, VH for green, and VV-VH for blue.
Parameters
Parameter | Description |
---|---|
Input raster | The input multiband raster data. |
Method | Specifies the method that will be used to extract bands.
|
Red expression | The calculation assigned to the first band. A band name, band ID, or an algebraic expression using the bands. The supported operators are unary: plus (+), minus (-), times (*), and divide (/). |
Green Expression | The calculation assigned to the second band. A band name, band ID, or an algebraic expression using the bands. The supported operators are unary: plus (+), minus (-), times (*), and divide (/). |
Blue expression | The calculation assigned to the third band. A band name, band ID, or an algebraic expression using the bands. The supported operators are unary: plus (+), minus (-), times (*), and divide (/). |
