v.report generates a table showing the area present in each of the categories of a user-selected data layer.
Area is given in hectares, square meters, and square kilometers. If the units option is used, area is given in acres, square feet, and square miles.
Feet and acre units are always reported in their common versions (i.e. the International Foot, exactly 5280 feet in a mile), even when the location’s standard map unit is the US Survey foot.
v.report works on the full map data; therefore, the current region is ignored. If you wish to spatially limit the statistics, a map subset must be created with v.in.region and v.overlay, and then run v.report on the new map.
North Carolina sample dataset:
v.report zipcodes_wake option=area units=hectares
In the output, there is an extra column added containing the results.
v.in.region, v.to.db, v.overlay
