Classify function

Available with Spatial Analyst license.

  • Overview
  • Notes
  • Parameters

Overview

Classify a raster dataset based on an Esri Classifier Definition (.ecd) file and raster dataset inputs. The .ecd file contains all the information needed to perform a specific type of Esri-supported classification.

For more information about classification, see Understanding segmentation and classification.

License:

This function requires the ArcGIS Spatial Analyst extension to be enabled.

Notes

The .ecd file used in the Classify function contains all the information for a specific dataset and classifier and is generated by the classification training tools, such as the Train Support Vector Machine or Train Random Trees tools.

The two input parameters need to be in the same order as they were entered into the classification training tools that generated the .ecd file.

Parameters

ParametersDescription

Input Raster

The raster dataset you want to classify.

Input Definition File

The input Esri Classifier Definition (.ecd) file that contains the statistics and other classification information for the specific dataset, classifier, and chosen attributes.

Input Raster 2

An optional ancillary raster dataset to incorporate into the classifier, such as a segmented image, multispectral image, or elevation data, used to generate a more robust classification definition for your dataset. The raster dataset for this parameter must match the one used to create the input Esri Classifier Definition file.
