参数 | 说明 | 数据类型 |
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. (默认值为 3) | Integer |
kernel_rows | The number of pixel rows to use in your focal neighborhood dimension. (默认值为 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.
(默认值为 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.
