Statistics

サマリー

Calculates statistics for each cell of an image based on a defined focal neighborhood.

説明

For more information about the methods and band orders used with this function, see the Statistics 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.

パラメーター	説明	データ タイプ
raster	The input raster on which to perform focal statistics.	Raster
kernel_columns	The number of pixel columns to use in your focal neighborhood dimension. (デフォルト値は次のとおりです 3)	Integer
kernel_rows	The number of pixel rows to use in your focal neighborhood dimension. (デフォルト値は次のとおりです 3)	Integer
stat_type	Specify the type of statistics to calculate. max— Calculates the maximum value of the pixels within the neighborhood. mean— Calculates the average value of the pixels within the neighborhood. This is the default. min— Calculates the minimum value of the pixels within the neighborhood. standarddeviation—Calculates the standard deviation value of the pixels within the neighborhood. median—Calculates the median value of the pixels within the neighborhood. majority— Calculates the majority value, or the value that occurs most frequently, of the pixels within the neighborhood. minority— Calculates the minority value, or the value that occurs least frequently, of the pixels within the neighborhood. (デフォルト値は次のとおりです None)	String
fill_no_data_only	Specify whether NoData values are ignored in the analysis. True—Fills NoData pixels only. This is the default. False—NoData pixels will not be filled. (デフォルト値は次のとおりです False)	Boolean
