Creating Multiband JPEG 2000 Files

GeoExpress allows the creation of multiband JPEG 2000 files from a collection of single-band grayscale image files. The input files must all have the same dimensions, resolution, bit depth, and geographic positioning. Empty bands are allowed, and treated as zero data.

  1. Select Add color composite image to encode... from the File menu.

    The Add Color Composite Image dialog box appears.

  2. Select a color space for the image from the drop-down menu, either RGB or Multispectral. RGB populates the list box with editable red, green, and blue bands. Multispectral populates the list box with bands that range from 1 to n. You can change the number of bands in a multispectral image by clicking Edit number of bands... and typing in a new value.

  3. To add an image file to a band, select the desired band and then click Edit file name.... The Edit File Name dialog box appears as shown below.

  4. Type in a file name or click Browse... to bring up a file browser. If you want to remove a file from a given band, simply clear the text from the file name field. A color composite image must have at least one band specified.
