摘要
创建栅格对象,其中每个像素包含输入栅格集中的值,具体取决于等级输入栅格的值。
语法
Rank (rank_raster, rasters, {extent_type}, {cellsize_type}, {process_as_multiband})
参数 | 说明 | 数据类型 |
rank_raster | The input raster that defines the rank position to be returned. | Raster |
rasters [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 are processed.
(默认值为 False) | Boolean |
数据类型 | 说明 |
Raster |
输出栅格。 |
代码示例
根据等级栅格计算输入栅格集的等级。
# Import system modules
import arcpy
from arcpy.ia import *
#Set the local variables
rank_raster = r"c:\temp\value_raster.tif"
rasters = [r"c:\temp\raster1.tif", r"c:\temp\raster2.tif", r"c:\temp\raster3.tif"]
#Execute
output_raster = Rank(rank_raster, rasters, "UnionOf", "FirstOf", True)
