You can try r.category, for example: r.category Classification_Post rules=classes_description.rules Where "classes_description" is a simple text file that might look like: --%<--- 1:2:Water 3:4:Water (Near Coast) 5:6:Water (Along Coast) 7:9:10:12:14:18:Shallow Water, Coast, Wet Ground 8:16:17:Urban 11:15:Some Vegetation 13:Shadows 19:22:Wet Ground 20:21:23:24:25:27:Some Vegetation 2 26:30:Other Vegetation (Low/Urban Green), incl. Some Bare Ground 28:29:Other Vegetation --->%-- Have a look at the manual for details. You can then use r.report to produce a nice summary, e.g. r.report Classification_Post units=h -nh pw=60 would give: +----------------------------------------------------------+ | Category Information | | | #|description | hectares| |----------------------------------------------------------| | 1|2:Water. . . . . . . . . . . . . . . . . . .| 98.664200| | 2| . . . . . . . . . . . . . . . . . . . . . .| 5.367125| | 3|4:Water (Near Coast) . . . . . . . . . . . .| 0.212725| | 4| . . . . . . . . . . . . . . . . . . . . . .| 0.333175| | 5|6:Water (Along Coast). . . . . . . . . . . .| 0.317275| | 6| . . . . . . . . . . . . . . . . . . . . . .| 0.536275| .... ... .. .
