     An object of class 'kasc' stores several maps in a data frame (one
     column per variable, and one row per pixel of the raster map).
     However, the features mapped are rarely rectangle-shaped, whereas
     the map are inevitably rectangles.  Therefore, a lot of pixels of
     the maps do not contain data.  The pixels of the map that do not
     contain data are 'NA' in this data frame. 
      It often occurs that several variables are not mapped for exactly
     the same area (that is, some pixels are 'NA' for some variables,
     and not for others). 'managNAkasc' will set to 'NA' all pixels
     that are not mapped for all variables.
