Reclass by ASCII File (Spatial Analyst)

Resumen

Reclassifies (or changes) the values of the input cells of a raster using an ASCII remap file.

Uso

• The input raster must have valid statistics. If the statistics do not exist, they can be created using the Calculate Statistics tool in the Data Management Tools toolbox.

• The output raster will always be of integer type. If the output assignment values in the ASCII file are floating-point values, an error message will be returned and the program will halt.

Sintaxis

ReclassByASCIIFile (in_raster, in_remap_file, {missing_values})

Parámetro	Explicación	Tipo de datos
in_raster	The input raster to be reclassified.	Raster Layer
in_remap_file	ASCII remap file defining the single values or ranges to be reclassified and the values they will become. Allowed extensions for the ASCII remap files are .rmp, .txt, and .asc.	File
missing_values (Opcional)	Denotes whether missing values in the reclass file retain their value or get mapped to NoData. DATA — Signifies that if any cell location on the input raster contains a value that is not present or reclassed in the remap file, the value should remain intact and be written for that location to the output raster. NODATA — A keyword signifying that if any cell location on the input raster contains a value that is not present or reclassed in the remap file, the value will be reclassed to NODATA for that location on the output raster.	Boolean

Valor de retorno

Nombre	Explicación	Tipo de datos
out_raster	The output reclassified raster. The output will always be of integer type.	Raster

Ejemplo de código

ReclassByASCIIFile example 1 (Python window)

example uses an ASCII remap file to reclassify the input raster.

import arcpy
from arcpy.sa import *
from arcpy import env  
env.workspace = "C:/sapyexamples/data"
outReclass = ReclassByASCIIFile("slope","remapslope.rmp")
outReclass.save("C:/sapyexamples/output/recslope")

ReclassByASCIIFile example 2 (stand-alone script)

This example uses an ASCII remap file to reclassify the input raster.

# Name: reclassbyasciifile_example02.py
# Description: Reclassifies  values of the input raster using an ASCII remap file
# Requirements: Spatial Analyst Extension

# Import system modules
import arcpy
from arcpy import env
from arcpy.sa import *

# Set environment settings
env.workspace = "C:/sapyexamples/data"

# Set local variables
inRaster = "slope"
inRemapFile = "remapslope.rmp"

# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")

# Execute Reclassify
outRaster = ReclassByASCIIFile(inRaster, inRemapFile)

# Save the output 
outRaster.save("C:/sapyexamples/output/recslope")
