Adding a multiband image for the classification

The Image Classification toolbar allows you to classify a multiband raster. A multiband satellite image is a typical example of a multiband raster.

To specify a source image for the classification analysis, add the image to ArcMap. Then choose the image layer in the Layer drop-down list on the Image Classification toolbar.

Steps:

1. Start ArcMap.
2. Add the Image Classification toolbar to ArcMap. Refer to the topic Adding the Image Classification toolbar for how to add it.
3. On the Standard toolbar, click the Add Data button.

   

4. On the Add Data dialog box, browse to the image on the disk and click Add.

   The image is added as a layer in the table of contents. The layer points to all the bands on the disk.

   

5. On the Image Classification toolbar, click the Layer arrow and click the image layer you just added.

   

   This specifies the source image for all the subsequent image classification tasks. All the bands associated with the image layer are used in the classification analysis.

Note:

To create a multiband image using a set of individual bands, use the Composite Bands tool and specify the individual bands as input.
