setfillvalue2d (2-dimensional Dataset)¶
setfillvalue2d _ [maskdt][mapdt]
_ll [cdt]
subroutine is used to create a mask in a 2-dimensional NetCDF using another map.
Combinations can be made for the statements of this subroutine by replacing [maskdt]
and [mapdt]
by one of the data types defined in the FPL library ([byte, short, int, float, double]
)
and [cdt]
by a defined suffix for the data type of the coordinates (f
for float and d
for double).
