You can even use one or more shapes in a shape file as maskout through output the shapes to a .wmp file.

With MeteoInfo, you can output the shapes of a shape file to a maskout grid data which could be used in maskout() function of GrADS.<br><br>The detailed information could be found in the help document of MeteoInfo.
