HighestPosition

摘要

创建栅格对象,其中每个像素包含栅格集中具有最大值的栅格的位置。

说明

有关此函数工作原理的详细信息,请参阅最高位置工具。

栅格对象所引用的栅格数据集是临时性的。 要将其设置为永久,可以调用栅格对象的 save 方法。

语法

HighestPosition (rasters, {extent_type}, {cellsize_type})
参数说明数据类型
rasters
[rasters,...]

The list of input rasters.

None
extent_type

The method that will be used to compute the extent of the output when the input rasters have different extents.

  • FirstOfThe output extent is defined using the extent of the first input raster.
  • LastOfThe output extent is defined using the extent of the last input raster.
  • IntersectionOfThe output extent is defined as the intersecting area of the input rasters.
  • UnionOfThe output extent is defined as the total extent of the input rasters.

(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.

  • FirstOfThe output pixel size is defined using the pixel size of the first input raster.
  • LastOfThe output pixel size is defined using the pixel size of the last input raster.
  • MaxOfThe output pixel size is defined using the maximum pixel size of the input rasters.
  • MeanOfThe output pixel size is defined using the mean of both input rasters.
  • MinOfThe output pixel size is defined using the minimum pixel size of the input rasters.

(默认值为 FirstOf)

String
返回值
数据类型说明
Raster

输出栅格。

代码示例

HighestPosition 示例

计算栅格集中具有最大值的栅格。

# Import system modules
import arcpy
from arcpy.ia import *

#Set the local variables
rasters = [r"c:\temp\raster1.tif", r"c:\temp\raster2.tif", r"c:\temp\raster3.tif"] 

#Execute
Highest_raster = HighestPosition(rasters, "UnionOf", "FirstOf")
