Adding a single-band raster
You can add a raster dataset with only one band, or you can add one band from a multiband raster dataset.
- Click the Add Data button on the Standard toolbar.
- Click the Look in drop-down arrow and navigate to the folder that contains the raster dataset.
- Click the single-band raster dataset.
ArcMap creates a new raster layer on the map that references the raster data source.
If the single band is part of a multiband raster dataset, double-click the dataset to expose the bands.
You can also drag and drop a raster from ArcCatalog, the Catalog window, or the Explorer window to ArcMap, ArcScene, or ArcGlobe.
