TSTool / Command / WriteWaterML

Overview

This command is under development. In particular, an evaluation is determining how best to map internal time series properties to the WaterML specification, including selecting reasonable defaults while allowing override of defaults. Recent work has focused on WaterML 2.

The WriteWaterML command writes time series to a WaterML XML and JSON format file. See the WaterML Input Type Appendix for more information about the file format. See also the WriteWaterML2 command, which focuses on WaterML 2.

Command Parameters

Parameter                          Description Default                           
Parameter Description Default
TSList Indicates the list of time series to process, one of:
  • AllMatchingTSID – all time series that match the TSID (single TSID or TSID with wildcards) will be processed.
  • AllTS – all time series before the command.
  • EnsembleID – all time series in the ensemble will be processed.
  • FirstMatchingTSID – the first time series that matches the TSID (single TSID or TSID with wildcards) will be processed.
  • LastMatchingTSID – the last time series that matches the TSID (single TSID or TSID with wildcards) will be processed.
  • SelectedTS – the time series are those selected with the SelectTimeSeries command.
 AllTS
TSID The time series identifier or alias for the time series to be processed, using the * wildcard character to match multiple time series. Required if TSList=*TSID.
EnsembleID The ensemble to process, if processing an ensemble. Required if TSList= EnsembleID.
OutputFile The WaterML output file. The path to the file can be absolute or relative to the working directory (command file location). Can be specified using ${Property} notation. None – must be specified.
Version The WaterML version to write:
  • WaterML-1.1- JSON
  • WaterML-2.0 – see WriteWaterML2 command, which is being phased in.
 WaterML-2.0
Precision The number of digits after the decimal for numerical output. 4 (in the future may default based on data type)
MissingValue The value to write to the file to indicate a missing value in the time series. As initialized when reading the time series or creating a new time series, typically -999, NaN, or another value that is not expected in data.
OutputStart The date/time for the start of the output. Use the global output period.
OutputEnd The date/time for the end of the output. Use the global output period.
