Reclassifying your data means replacing input cell values with new output cell values.

The most common reasons for reclassifying data are to

The following table lists the available Reclass tools, provides a brief description of each, and identifies if the tool works in ArcToolbox, Map Algebra, or ArcObjects.


Tool Description ArcToolbox Map Algebra ArcObjects
Lookup Creates a new raster by looking up values found in another field in the table of the input raster. X

X
Reclass Reclassifies or changes the value of the input cells using a remap table on a cell-by-cell basis within the Analysis window.

X X
Reclass by ASCII File Reclassifies or changes the value of the input cells using an ASCII remap table. X

X
Reclass by Table Reclassifies or changes the values of the input cells of a raster using a remap table. X

ReclassByRemap Reclassifies or changes the value of the input cells using a remap table.

X
Reclassify Reclassifies or changes the values in a raster. X

Slice Changes (slices) a range of values of the input cells within the analysis extent. The ranges are specified as zones of equal area or zones of equal intervals. In Map Algebra only, an option of using a remap table to specify zones is also available. X X X
