Summary
Reclassifies (or changes) the values of the input cells of a raster using an ASCII remap file.
Usage
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 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.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
Syntax
ReclassByASCIIFile(in_raster, in_remap_file, {missing_values})
Parameter | Explanation | Data Type |
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 (Optional) | Denotes whether missing values in the reclass file retain their value or get mapped to NoData.
| Boolean |
Return Value
Name | Explanation | Data Type |
out_raster | The output reclassified raster. The output will always be of integer type. | Raster |
Code sample
This 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")
This example uses an ASCII remap file to reclassify the input raster.
