ParameterType Class

Detailed Documentation

Example Usage

General

ParameterType objects are named objects that indicate how the values in a time series are to be interpreted with respect to the duration [1] of the time series values.

ParameterTypes have three contexts:

• RAW: The context for time series not associated with any data store type.

• CWMS: The context for CWMS time series. In this context the ParameterType name is part of the time series name

• DSS: The context for HEC-DSS time series. In this context the ParameterType name is not part of the time series name, but of its metadata

Required Information

• name

• context

Notes

ParameterType context-specific names and descriptions:

RAW	CWMS	DSS	Description
Total	Total	PER-CUM	Accumulation over duration
Maximum	Max	PER-MAX	Maximum value during duration
Minimum	Min	PER-MIN	Minimum value during duration
Constant	Const	CONST	Constant value over duration
Average	Ave	PER-AVER	Average value over duration
Instantaneous	Inst	INST-CUM (for Precip or Count)	Value at end of duration [2]
		INST-VAL (for others)

[1]

HEC-DSS time series do not specify separate intervals and durations, so the implied duration is the interval

Value at beginning of duration for BOP durations
