I have 7 bands of Landsat and I would like to combine all layers into one layer.

Can ArcMap 10 do this like Erdas software can?

  • Is this a single, multi-band image? – Paul Aug 2 '13 at 8:15

You need to use the Composite Bands ArcGIS Geoprocessing tool.

According to the ArcGIS Help,

This tool can also create a raster dataset containing subset of the original raster dataset bands. This is useful if you need to create a new raster dataset with a specific band combination and order.

Go to the following steps if you have ArcGIS 10:

  • windows - Image Image Analysis
  • Select all layers which you want to stack
  • Go to processing tool (Stack).

The files you have selected will be stacked into a one composite layer with colors and bands combination.
