Transformation - InterpolationSerial Linear

Description and usage

This transformation function is used to fill inner gaps in a time series. The inner gaps are filled with linearly interpolated data values.

...

This function has an option to define the maximum length of the gaps that should be filled. Gaps that are equal to or smaller than the defined maximum gap length will be filled with interpolated values. Gaps that are larger than the defined maximum gap length will not be filled.

Input/Output time series

In this function one input time series and one output time series must be identified.

• inputVariable: A time series with input values. This will typically contain inner gaps.
• outputVariable: A time series in which the output will be stored. The output series will contain all input values and the inner gaps will be filled.

Configuration

A basic configuration of the function is described below. This describes the main elements and attributes required and provides an example configuration.

...

<transformation id="interpolation serial linear">
	<interpolationSerial>
		<linear>
			<inputVariable>
				<variableId>input</variableId>
			</inputVariable>
			<maxGapLength>5</maxGapLength>
			<outputVariable>
				<variableId>output</variableId>
			</outputVariable>
		</linear>
</transformation>
