摘要
创建栅格对象,其中每个像素包含栅格集小于另一个栅格的次数。
语法
LessThanFrequency (value_raster, rasters, {extent_type}, {cellsize_type}, {process_as_multiband})
参数 | 说明 | 数据类型 |
value_raster | A value raster that will be referenced by the list of input rasters. | Raster |
rasters | The list of input rasters. | Raster |
extent_type | The method that will be used to compute the extent of the output when the input rasters have different extents.
(默认值为 FirstOf) | String |
cellsize_type | The method that will be used to compute the pixel size of the output when the input rasters have different pixel sizes.
(默认值为 FirstOf) | String |
process_as_multiband | Specifies how the bands of the input rasters will be processed.
(默认值为 False) | Boolean |
数据类型 | 说明 |
Raster |
输出栅格。 |
代码示例
计算输入栅格集小于值栅格的次数。
# Import system modules
import arcpy
from arcpy.ia import *
#Set the local variables
value_raster = r"c:\temp\value_raster.tif"
rasters = [r"c:\temp\raster1.tif", r"c:\temp\raster2.tif", r"c:\temp\raster3.tif"]
#Execute
LessThan_raster = LessThanFrequency(value_raster, rasters, "UnionOf", "FirstOf", True)
