Using the Mask function, specify one or more NoData values, or a range of valid pixel values, to be removed from an output raster.
Notes
The table below offers an example using NoData Interpretation.
Example of pixel value inputs and output
| Band 1 | Band 2 | Band 3 | NoData Interpretation | RGB |
|---|---|---|---|---|
NoData | 1 | 1 | All | 1 |
NoData | NoData | NoData | All | NoData |
NoData | 1 | 1 | Any | NoData |
NoData | NoData | NoData | Any | NoData |
Parameters
| Parameter name | Description |
|---|---|
Raster | The input raster. |
| NoData Interpretation | This refers to how NoData Values will impact the output image. You can select from the following two options:
|
| NoData Values | The NoData values can be specified for each band. You can specify more than one value by entering a space-delimited list. |
| Included Ranges | The included ranges can be specified for each band by specifying a minimum and maximum value; any values outside the range will be returned as NoData. A pixel is included if the pixel's value falls within any of the ranges specified. Therefore, if band 1 has a range of 5–10 and band 2 has a range of 15–20, and the pixel value for band 1 is 8, this pixel will not be masked. |
