out_aspect_raster = Aspect("elevation.tif")
out_aspect_raster.save("C:/arcpyExamples/outputs/aspect.tif")

Aspect example 2

This example calculates the aspect of the raster dataset.

# 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 Aspect function
out_aspect_raster = Aspect(in_raster)

# Save the output
out_aspect_raster.save("C:/arcpyExamples/outputs/aspect.tif")
