ArgStatistics

Resumen

Creates a raster object where each pixel contains the band index at which that pixel reached the statistical argument. If the input raster is multidimensional, the output raster object will contain dimension values instead of band indices.

Debate

For more information about how this function works, see the ArgStatistics 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

ArgStatistics (rasters, {stat_type}, {min_value}, {max_value}, {multiple_occurrence_value}, {ignore_nodata})

Parámetro	Explicación	Tipo de datos
rasters [rasters,...]	The input raster or list of rasters.	Raster
stat_type	Specifies the statistical argument to extract. MAX — The band index or dimension value at which the maximum pixel value is reached will be extracted. MIN — The band index or dimension value at which the minimum pixel value is reached will be extracted. MEDIAN — The band index or dimension value at which the median pixel value is reached will be extracted. DURATION — The longest dimension duration for which the pixel values fall between the minimum and maximum values. (El valor predeterminado es None)	String
min_value	The minimum pixel value to be used to extract the duration. This argument is required when the stat_type argument is set to DURATION. (El valor predeterminado es None)	Double
max_value	The maximum pixel value to be used to extract the duration. This argument is required when the stat_type argument is set to DURATION. (El valor predeterminado es None)	Double
multiple_occurrence_value	The pixel value to use to indicate that a given argument statistic was reached more than once in the input raster dataset. This argument is required when the stat_type argument is set to MIN or MAX. (El valor predeterminado es 100)	Integer
ignore_nodata	Specifies whether to ignore NoData values in the calculation. True—The analysis will include all valid pixels in the input rasters and ignore any NoData pixels. False—The analysis will result in NoData if there are any NoData values for the pixels in the input rasters. (El valor predeterminado es True)	Boolean

Valor de retorno

Tipo de datos	Explicación

ArgStatistics example

Extracts the dimension value at which the maximum temperature was reached for the input multidimensional raster.

import arcpy

argstat_raster = arcpy.sa.ArgStatistics("Temperature_30_years.crf", "MAX","","", 9999)
