# RS_AddBand

Introduction: Adds a new band to a raster `toRaster` at a specified index `toRasterIndex`. The new band's values are copied from `fromRaster` at a specified band index `fromBand`.
If no `toRasterIndex` is provided, the new band is appended to the end of `toRaster`. If no `fromBand` is specified, band `1` from `fromRaster` is copied by default.

!!!Note
    IllegalArgumentException will be thrown in these cases:

    - The provided Rasters, `toRaster` & `fromRaster` don't have same shape.
    - The provided `fromBand` is not in `fromRaster`.
    - The provided `toRasterIndex` is not in or at end of `toRaster`.

Format:

```
RS_AddBand(toRaster: Raster, fromRaster: Raster, fromBand: Integer = 1, toRasterIndex: Integer = at_end)
```

```
RS_AddBand(toRaster: Raster, fromRaster: Raster, fromBand: Integer = 1)
```

```
RS_AddBand(toRaster: Raster, fromRaster: Raster)
```

Since: `v1.5.0`

SQL Example

```sql
SELECT RS_AddBand(raster1, raster2, 2, 1) FROM rasters
```

Output:

```
