Create RGB
The Create RGB tool is used to easily generate composite images from a base layer. For example, you can generate a true RGB image and a false color composite from a multispectral layer with this tool, allowing you to easily compare the two images without having to modify the settings of the original layer
Usage
The Create RGB dialog allows you to select a raster layer from which the
composite will be created. Once done, use the R/G/B channel dropdowns to map a
band in the input layer to the corresponding channel in the output layer. Select
an output name and click Create composite
to add the layer to your project.
Warning
This composites created will ONLY have the chosen RGB bands, making it useful for visualization but not analysis. The original layer will need to be used for analysis.
