An overview of the Reclass toolset

Available with Spatial Analyst license.

Available with 3D Analyst license.

The Reclass tools provide a variety of methods that allow you to reclassify or change input cell values to alternative values.

The most common reasons for reclassifying data are to accomplish the following:

  • Replace values based on new information.
  • Group certain values together.
  • Reclassify values to a common scale (for example, for use in a suitability analysis or for creating a cost raster for use in the Cost Distance tool).
  • Set specific values to NoData or set NoData cells to a value.
  • Learn more about reclassification

There are several approaches to reclassifying your data. The methods of reclassification and the tools that perform them are:

  • Individual values. (Lookup, Reclassify)
  • Ranges of values. (Reclass by ASCII File, Reclass by Table, Reclassify)
  • Intervals. (Slice)
  • Continuous values using functions. (Rescale by Function)

There are several approaches to reclassifying your data. The methods of reclassification and the tools that perform them are:

  • Learn how to reclass by individual values
  • Learn how to reclass by ranges of values
  • Learn about reclassification tables
  • Learn how to group values into intervals or by area
  • Learn how to rescale continuous data using functions

The following table lists the available tools and provides a brief description of each.

ToolDescription

Lookup

Creates a new raster by looking up values found in another field in the table of the input raster.

Reclass by ASCII File

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

Reclass by Table

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

Reclassify

Reclassifies (or changes) the values in a raster.

Rescale by Function

Rescales the input raster values by applying a selected transformation function and then transforming the resulting values onto a specified continuous evaluation scale.

Note:

This tool is available only with a Spatial Analyst license.

Slice

Slices or reclassifies the range of values of the input cells into zones of equal interval, equal area, or by natural breaks.
