Notes:
1) The 'grid2shpasciigrid' serializer can only output one time step so in case the grid is part of a timeseries the relativeViewperiod needs to be set to select a range of which only the first timestep will be used.
...
3) The exportMissingValue can be used to replace the given missing values by NaN (Not A Number) values given number to indicate that there is no valid data, ArcGIS will display such records as '0' instead of -999 in this example.this option is required to use the resulting files with ArcGIS as the default setting using 'NaN' to represent missing values is not supported by ArcGIS.
