AspectSlope

摘要

用于创建可同时显示表面坡向和坡度的栅格对象。

说明

有关此函数工作原理的详细信息，请参阅坡向坡度栅格函数。

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

AspectSlope (raster, {z_factor})

参数	说明	数据类型
raster	The input elevation raster.	Raster
z_factor	The z-factor is a scaling factor used to convert the elevation values for two purposes: To convert the elevation units (such as meters or feet) to the horizontal coordinate units of the dataset, which may be feet, meters, or degrees. To add vertical exaggeration for visual effect. If the x,y units and z units are in the same units of measure, the z-factor should be set to 1. The z-values of the input surface are multiplied by the z-factor when calculating the final output surface. (默认值为 1)	Double

返回值

数据类型	说明
Raster	输出栅格。

代码示例

AspectSlope 示例 1

本示例将计算栅格的坡向和坡度。

from arcpy.ia import *
out_aspectslope_raster = AspectSlope("elevation.tif", 3)
out_aspectslope_raster.save("C:/arcpyExamples/outputs/aspectslope.tif")

AspectSlope 示例 2

本示例将计算栅格的坡向和坡度。

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

# Set the analysis environments
arcpy.env.workspace = "C:/arcpyExamples/data"

# Set the local variables
in_raster = "elevation.tif"

# Execute the AspectSlope function
out_aspectslope_raster = AspectSlope(in_raster, 3)

# Save the output
out_aspectslope_raster.save("C:/arcpyExamples/outputs/aspectslope.tif")
