Summarize Categorical Raster (Image Analyst)

Summary

Generates a table containing the pixel count for each class, in each slice of an input categorical raster.

Usage

  • Use this tool to calculate the number of pixels in each category for every slice in a multidimensional, categorical raster dataset. For example, calculate the number of pixels in each land cover class for a multidimensional raster containing 30 years of land-cover data.

  • The input raster dataset must be an integer type raster. If a raster attribute table exists, the tool will use the unique values in the table to compute pixel count. If a raster attribute table does not exist, the tool will scan pixels to find unique values. You can use the Build Raster Attribute Table tool to construct an attribute table for the input raster.

  • If the input raster has a raster attribute table with a Class_Name or ClassName field, the output table will use the names listed in that field. Otherwise, the output table will use class values from the Class_Value or ClassValue field. The field names are not case sensitive.

  • Supported multidimensional raster datasets include Cloud Raster Format (CRF), multidimensional mosaic datasets, or multidimensional raster layers generated by netCDF, GRIB, or HDF format files.

Parameters

LabelExplanationData Type
Input Categorical Raster

The input multidimensional raster of integer type.

Raster Dataset; Raster Layer; Mosaic Dataset; Mosaic Layer; Image Service; String
Output Summary Table

The output summary table. Geodatabase, database, text, Microsoft Excel, and comma-separated value (CSV) tables are supported.

Table
Dimension
(Optional)

The input dimension to use for the summary. If there is more than one dimension and no value is specified, all slices will be summarized using all combinations of dimension values.

String
Area Of Interest
(Optional)

The polygon feature layer containing the area or areas of interest to use when calculating the pixel count per category. If no area of interest is specified, the entire raster dataset will be included in the analysis.

Feature Layer
Area Of Interest ID Field
(Optional)

The field in the polygon feature layer that defines each area of interest. Text and integer fields are supported.
