Determines which values from the input raster are NoData on a cell-by-cell basis.
Returns a value of 1 if the input value is NoData and 0 for cells that are not.
Is Null can be used along with the Con tool to change NoData cells to a value.
If the input is a multiband raster, the output will be a multiband raster. The tool will perform the operation on each band in the input.
If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.
| Label | Explanation | Data Type |
Input raster | The input raster being tested to identify the cells that are NoData (null). The input can be either integer or floating-point type. | Raster Layer |
| Label | Explanation | Data Type | Output raster | The output raster. The output identifies with an integer value of 1 which cells in the input are NoData. If the input is any other value, the output is 0. | Raster |
IsNull(in_raster)
| Name | Explanation | Data Type |
in_raster | The input raster being tested to identify the cells that are NoData (null). The input can be either integer or floating-point type. | Raster Layer |
| Name | Explanation | Data Type | out_raster | The output raster. The output identifies with an integer value of 1 which cells in the input are NoData. If the input is any other value, the output is 0. | Raster |
