Time Series Data Objects

There are two types of time series data (TSD) objects in ICMLive Operator Client: Scalar Time Series Data and Spatial Time Series Data. These objects provide an intermediate store between external data sources (such as SCADA/telemetry or RADAR) and a run.

The main differences between Scalar and Spatial time series data objects are shown in the table below.

Information stored in each time series data point

In a Scalar TSD, each time series data point has no geometry (i.e. no polygons) and has only one value.

Each time series data point in a Spatial TSD stores a number of polygons and a value for each of these polygons.

Number of datastreams and data sources

Scalar TSDs can have many streams and data sources defined.

Spatial TSDs can only contain one stream (and only one data source).

Spatial data requires much more storage than scalar data so limiting Spatial TSDs to one stream significantly helps partition the storage. Also, a model tends to have many scalar data sources (and only a few spatial data sources) so it is more manageable to keep a number of streams together in one Scalar TSD rather than have many tree objects.

Display in ICMLive Operator Client

Scalar values are displayed alongside their timestamp in a grid (see Time Series Data Grid).

Spatial time series values are displayed in the GeoPlan as a theme. See Displaying Spatial Rainfall on the GeoPlan.

Time series data objects are created and set up in InfoWorks ICM Ultimate or ICMLive Configuration Manager.

Edit time series data

You can edit data contained in time series data objects. See Editing Time Series Data for more information.

Update time series data from data source

Time series data may be updated from external data sources. See Updating Time Series Data for further details.
