Reclass by Table (3D Analyst)

License Level:BasicStandardAdvanced

Summary

Reclassifies (or changes) the values of the input cells of a raster using a remap table.

Usage

Syntax

ReclassByTable_3d (in_raster, in_remap_table, from_value_field, to_value_field, output_value_field, out_raster, {missing_values})
ParameterExplanationData Type
in_raster

The input raster to be reclassified.

Raster Layer
in_remap_table

Table holding fields defining value ranges to be reclassified and the values they will become.

Table View
from_value_field

Field holding the beginning value for each value range to be reclassified.

This is a numeric field of the input remap table.

Field
to_value_field

Field holding the ending value for each value range to be reclassified.

This is a numeric field of the input remap table.

Field
output_value_field

Field holding the integer values to which each range should be changed.

This is an integer field of the input remap table.

Field
out_raster

The output reclassified raster.

The output will always be of integer type.

Raster Dataset
missing_values
(Optional)

Denotes whether missing values in the reclass table retain their value or get mapped to NoData.

  • DATASignifies that if any cell location on the input raster contains a value not present or reclassed in a remap table, the value should remain intact and be written for that location to the output raster. This is the default.
  • NODATA Signifies that if any cell location on the input raster contains a value not present or reclassed in a remap table, the value will be reclassed to NoData for that location on the output raster.
Boolean

Code Sample

ReclassByTable example 1 (Python window)

This example uses a remap table to reclassify the input raster.

import arcpy
from arcpy import env  
env.workspace = "C:/data"
arcpy.ReclassByTable_3d("slope","remapslope","C:/sapyexamples/output/recslope",
                        "FROM","TO","OUT", "NODATA")
ReclassByTable example 2 (stand-alone script)

This example uses a remap table to reclassify the input raster.

# Name: ReclassByTable_Ex_02.py
# Description: Reclassifies the values of the input raster using a remap table.
# Requirements: 3D Analyst Extension

# Import system modules
import arcpy
from arcpy import env

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

# Set local variables
inRaster = "slope"
inRemapTable = "remapslope"
outRaster = "C:/output/recslope"

# Check out the ArcGIS 3D Analyst extension license
arcpy.CheckOutExtension("3D")

# Execute Reclassify
arcpy.ReclassByTable_3d(inRaster, inRemapTable, outRaster, "FROM","TO","OUT",
                        "NODATA")
