The Raster 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.
- Set specific values to NoData or set NoData cells to a value.
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)
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
The following table lists the available tools and provides a brief description of each.
| Tool | Description |
|---|---|
Creates a new raster by looking up values found in another field in the table of the input raster. | |
Reclassifies (or changes) the values of the input cells of a raster using an ASCII remap file. | |
Reclassifies (or changes) the values of the input cells of a raster using a remap table. | |
Reclassifies (or changes) the values in a raster. | |
Slices or reclassifies the range of values of the input cells into zones of equal interval, equal area, or by natural breaks. |
