Exploring the Numeric Grid Reclass Dialog Box

The Numeric Grid Reclass tool enables you to reclassify the values contained in a numeric grid so
that it will be more suitable for analysis.

The Numeric and Classified buttons enable you to specify the grid type for the resulting grid. For
numeric grids, the classes have numeric values beginning with lowest value in the range. For
classified grids, the classes have descriptions beginning with Class 1. You can change values by
double-clicking in a field.

The Intervals button opens the Interval dialog box, which enables you to define the following values:

The Minimum box enables you to define the lowest value in the grid that will be used in the
reclassification. Any cells with a value less than the Minimum setting will receive the null value in
the resulting grid. This setting defaults to the lowest value in the grid.

The Maximum box enables you to define the highest value in the grid that will be used in the
reclassification. Any cells with a value greater than the Maximum setting will receive the null
value in the resulting grid. This setting defaults to the highest value in the grid.
