Records, in each output cell, the minority value (the value that appears least often) of all cells in the <value_grid> that belong to the same zone as the output cell. Zones are identified by the values of the cells in the input <zone_grid>.
Illustration
Usage tips
Map Algebra
The zone and value rasters must be integer.
The data type of the output raster will be integer.
When there is a tie for the minority value in a zone, the output for all cell locations in the zone are assigned the lowest of the tied values.
Learn more about how to specify the input raster dataset in the Map Algebra expression of Raster Calculator.

ZonalMinority(<zone_grid>, <value_grid>, {DATA | NODATA})
Parameter | Explanation |
<zone_grid> | An integer raster that identifies the zone for each cell.
The zone raster can be an expression resulting in a raster. |
<value_grid> | An integer raster that defines the values of the cells in which the minority value is to be calculated.
The minority of the values of the value raster in each zone will be assigned to every cell in that zone on the output raster. The value raster may be an expression resulting in a raster. |
{DATA | NODATA} | A keyword defining the manner in which NoData values on the <value_grid> that fall within a zone defined by the <zone_grid> will influence the output result.
