[[de:NCPLOT: Min_Water_Depth]]

This page illustrates the effect of the control parameter "Min_Water_Depth" of
the steering file [[NCPLOT.DAT]].

Data at places with low water coverage can be excluded from the presentation
by using the parameter "Min_Water_Depth".

In comparison with the current total water depth the value "Min_Water_Depth"
is used additionally to distinguish "valid" and "invalid" data.
In case of Min_Water_Depth = 0.0, the data are used in respect of valid or invalid values
exactly as they exists in the CF NetCDF file.

The method works only on variables that have a variable with the standard name
"sea_floor_depth_below_sea_surface" as "ancillary_variable".
The CF-NetCDF output of UnTRIM programs fulfills this requirement.


=Impact of Min_Water_Depth on the presentation=
Areas with a current water coverage less than the specified "Min_Water_Depth" value are treated as
"fallen dry". Existing "valid" data at such a place become "invalid" and are not shown. This method
usually improves the appearance.
