Creating Color Composite Images

GeoExpress allows you to combine up to 3 single-band images to form a color composite. You can assign to each image one of three color band assignments: red, green or blue. This is useful when working with NITF (National Image Transmission Format) files that can be segregated into separate color files.

For JPEG 2000 images, see Creating Multiband JPEG 2000 Files.

There are three command line switches that control the composite:

This is the only encoding operation that does not require the ‑i switch for an input file. The ‑i switch cannot be used in a color composite operation.

Files comprising a composite operation have the following restrictions:

For example, to create a single RGB composite image using the images

you would use the following command:

mrsidgeoencoder -redband red.ntf -blueband blue.ntf -greenband green.ntf -o mycomposite.sid
