gts encoder conversion multivariate
MVINDEXSPLIT function transforms an input Geo Time Series™ or Encoder by interpreting its Multi Value values and producing multiple output encoders.
The transformation works as follows, whenever
MVINDEXSPLIT encounters a value in Multi Value format at
elev as optional geo components, it decodes that value and adds each of its elements to a separate Encoder identified by the element index (first element being at index 0).
Each element is added with
tick as its timestamp and
elev as its geo components, unless it has its own geo information.
If the transformation encounters a value which is not in Multi Value format, its assumes it is an element found at index 0 and adds it to the associated encoder.
Once the input has been scanned completely, the resulting encoders are renamed, either by looking up the renaming parameter in a map or by appending
:INDEX to the original name.
The labels and attributes from the input are preserved.
Optionaly a list of indices or indices ranges can be specified to only produce encoders for the indices which are specified or fall within a specified range.
