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
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.
