# RS_MakeRaster

Introduction: Creates a raster from the given array of pixel values. The width, height, geo-reference information, and
the CRS will be taken from the given reference raster. The data type of the resulting raster will be DOUBLE and the
number of bands of the resulting raster will be `data.length / (refRaster.width * refRaster.height)`.

Return type: `Raster`

Since: `v1.6.0`

Format: `RS_MakeRaster(refRaster: Raster, bandDataType: String, data: ARRAY[Double])`

* refRaster: The reference raster from which the width, height, geo-reference information, and the CRS will be taken.
* bandDataType: The data type of the bands in the resulting raster. Please refer to the `RS_MakeEmptyRaster` function for the accepted values.
* data: The array of pixel values. The size of the array cannot be 0, and should be multiple of width * height of the reference raster.

SQL example:

```sql
WITH r AS (SELECT RS_MakeEmptyRaster(2, 3, 2, 0.0, 0.0, 1.0, -1.0, 0.0, 0.0, 4326) AS rast)
SELECT RS_AsMatrix(RS_MakeRaster(rast, 'D', ARRAY(1, 2, 3, 4, 5, 6))) FROM r
```

Output:

```
