I imported the swi.tiff to grass,got four raster ,r g b and other ,then I composite them , The composited raster have five category: 0 9321 26425 31744 32736 And I use the r.to.vect commond to change it to to a vecor layer. then extract: v.extract input=swi...@permanent output=swi_32736 type=point,area layer=1 new=-1 list=32736 --overwrite then I display the swi_32736 ,its shape is not close to which in the tiff. > > Have you set your working region correctly ?
