       output=string
           Name for output raster map

       lesser=float

DESCRIPTION

       r.reclass.area reclasses a raster map greater or less than a user specified area size (in hectares).

EXAMPLE

       In this example, the ZIP code map in the North Carolina sample dataset location  is  filtered  for  large
       areas:
       g.region rast=zipcodes -p
       r.report zipcodes unit=h
       # extract only areas > 2000 ha:
       r.reclass.area input=zipcodes output=zipcodes_larger2000ha greater=2000
