I finished classification (use SACP in QGIS), and got a classificated raster. Now I want to obtain characteristics such as sum area of class, areas of different polygons separately, etc.
I tried use shp. file, which created in SACP (i tried calculate areas by export/add the geometry field); I tried to use r.stats GRASS command but i have not gotten characteristics of area linked with Class.
Maybe somebody can give good suggestion or ready recipe about this?
