Mask

Resumen

Creates a raster object by specifying one or more NoData values or a range of valid pixel values.

Debate

For more information about how this function works, see the Mask raster function.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.

Sintaxis

Mask (raster, {no_data_values}, {included_ranges}, {no_data_interpretation})

Parámetro	Explicación	Tipo de datos
raster	The input raster.	Raster
no_data_values [no_data_values,...]	The NoData value or list of values. Values can be type Double or Integer. (El valor predeterminado es None)	Double
included_ranges [included_ranges,...]	The range of valid pixel values to be included in the output raster. Values can be type Double or Integer. (El valor predeterminado es None)	Double
no_data_interpretation	Specifies how the NoData values will be displayed in the output raster. 0 —All—The NoData values you specify for each band must occur in the same cell for the output image to contain the NoData cell. 1 —Any—If the NoData value you specify occurs for a cell in a specified band, that cell in the output image will be NoData. (El valor predeterminado es None)	Integer

Valor de retorno

Tipo de datos	Explicación
Raster	The output raster.
