Introduction
The FEWS PI REST Web Service allows interacting with Delft-FEWS using a REST API.
Developers documentation
For API Developers it is recommended to use the Open API Documentation. Please see: Open API Specification Documentation
WebServices Configuration (since 2022.02)
Since 2022.02 a WebServices xml configuration file is supported (and replaces the deprecated FewsPiServices.properties file). See FEWS WebServices Configuration File (since 2022.02)
Configuration properties
Deprecated since 2022.02. Will be removed in a future release of the Delft-FEWS Web Services. Please use the WebService Configuration instead.
The FewsPiService.properties file can be used to make service specific configurations available. This is a property file that is located in the FEWS configuration in the directory for a standalone system or should be uploaded with the ConfigManager for a live system:
%REGION_HOME%/Config/PiClientConfigFiles/FewsPiService.properties
For more information about the possible properties, see FEWS Web Services configuration FewsPiService.properties.

- qualifierIds (string): Subset of qualifiers for which to retrieve time series. This parameter has to be duplicated to specify multiple qualifierIds. To indicate that no qualifier is available, use qualifierIds: "none"
- showProducts (boolean): Toggle to display product information that is assigned to a forecast. (Since 2019.02). See below for an example.
- showStatistics (boolean): Toggle to return statistics information about time series. Typically used in combination with onlyHeaders. Returns additional information about data availability of time series (Since 2015.01). These statistics are only provided if there is any data, otherwise they are left out.
- firstValueTime: First time with a value in the time series
- lastValueTime: Last time with a value in the time series
- maxValue: Maximum value in the time series
- minValue: Minimum value in the time series
- valueCount: Number of values in the time series
- showThresholds (boolean): Option to toggle the returning of threshold information in the headers
- showEnsembleMemberIds (boolean): Show ensemble member ids instead of ensemble member indices.
- timeSeriesType (string): Explicitly filter on a specific time series type. (Since 2020.01). Possible values are: EXTERNAL_HISTORICAL, EXTERNAL_FORECASTING, SIMULATED_HISTORICAL, SIMULATED_FORECASTING.
- thinning (long): unit ms/pixel. Thinning is used to retrieve the visually interesting time steps of time series. It tries to keep the peaks and gaps and minimizes the number of time steps that have to be retrieved. It is typically used for visualizations. The value to be specified should be equal to the view period in milliseconds of the time series that is visualized divided by the number of pixels that are available for display. For example: visualizing a view period of 5 years (157784760000 milliseconds) on a display of 1024 pixels, the thinning parameter should be set to 157784760000/1024 = 15408668. (Since 2019.02)
- useMilliseconds (boolean) Optional argument. Default is false. If it is set to true, the response will contain milliseconds. See example below. Available in 2017.02 and from 2019.02
- startCreationTime (dateTime format: yyyy-MM-ddTHH:mm:ssZ): Start time of search period that looks for creation time of time series. Note: creation time of time series is actually the creation time of the task that produced/imported these time series.
- startForecastTime (dateTime: yyyy-MM-ddTHH:mm:ssZ): Start time of search period that looks for time series produced by forecasts that have their forecast time within this period. Format: yyyy-MM-ddTHH:mm:ssZ. If left empty all forecasts up to the endForecastTime will be used as search period.
- startTime (dateTime: yyyy-MM-ddTHH:mm:ssZ): Start time of search period that looks for timeseries values that are within this period. If the startTime doesn't match a timestamp of the time series, the closest timestamp before the startTime, will also be returned. Format: yyyy-MM-ddTHH:mm:ssZ. Take note that if no startTime is specified, the start time of the requested period will be set to the current time minus one day.
- taskRunIds (string): Subset of task run ids for which to retrieve time series. This parameter has to be duplicated to specify multiple taskRuns. N.B. cannot be used in combination with a filterId or with startTime and/or endTime.
- useDisplayUnits (boolean): Export values using display units.
- importFromExternalDataSource (boolean, default true): import data from external data source (Archive). (since 2017.02)
- timeStepId (string): filter time series by the timestep that has been configured in the TimeSteps.xml. (since 2018.02). N.B.: It is not required to use the timeStepId's in the filter configurations to be able to use them as long as they have been configured in the TimeSteps.xml.
- timeStepMillis (integer): filter time series by an equidistant timestep with a duration of the given number of milliseconds. This can be used in cases where no timestep Id has been configured in TimeSteps.xml. Cannot be used in combination with timeStepId.
Response
- PI-XML

- BINARY: only supported when running in embedded tomcat in the Operator Client or Stand Alone.
Filter combinations
Not all parameters can be combined. The following combinations are commonly used valid combinations of parameters. The main way to filter timeSeries is by using filterIds or taskRunIds.
filterId Only the default filter or one of its subfilters can be applied) | taskRunIds One or more taskRunIds can be specified | startTime, endTime | startCreationTime, endCreationTime | startForecastTime, endForecastTime | |
|---|---|---|---|---|---|
| Apply a filter to the time series. The requested period will be set to the current time minus one day and one hour ago until the current time plus one day and one hour | X(1) | ||||
| Get all time series created by one or more taskRuns. All time steps of the matching time series are returned. | X | ||||
| Get the time series created by a taskrun and apply a filter from the Filters configuration. startTime and endTime cannot be specified. The complete time series will be returned. Since 2020.01. | X | X | |||
| Apply a filter to the time series and return time steps that are in the startTime and endTime range. If the startTime or endTime doesn't match a timestamp of the time series, the closest time step before startTime and/or after endTime is returned as well. | X | X | |||
| Apply a filter to the time series. Only time series created during the startCreationTime and endCreationTime period will be returned. All time steps of the matching time series are returned. | X | X | |||
| Apply a filter to the time series. Return only time series created during the creation time period. Only return timesteps in the startTime and endTime range. | X | X | X | ||
| Apply a filter to the time series. Return only time series with external forecast times in the startForecastTime and endForecastTime period. Only return timesteps in the startTime and endTime range. | X | X | X | ||
| Apply a filter to the time series. Return only time series with external forecast times in the startForecastTime and endForecastTime period that were created in the creation time period. Only return time steps in the startTime and endTime range. | X | X | X | X | |
| Apply a filter to the time series. Return only time series created during the creation time period. All time steps of the matching time series are returned. (before 2020.01 startTime and endTime had to be specified). | X | X | |||
| Apply a filter to the time series. Return only time series with external forecast times in the startForecastTime and endForecastTime period. All time steps of the matching time series are returned. | X | X | |||
| Apply a filter to the time series. Return only time series created during the creation time period and with external forecast times in the startForecastTime and endForecastTime period. All time steps of the matching time series are returned. | X | X | X |
(1): Take note that if no startTime and endTime are specified, the requested period will be set to the current time minus one day and one hour ago until the current time plus one day and one hour.
no data vs no time series
If a timeseries query has matching timeseries sets a http 200 code will be returned and the headers of all matching timeseries sets will be returned.
If there is any data for the requested period, the headers will be followed by the actual events that contain the data. So even if no data is available for the requested period,the headers are always returned.
It is also possible that a timeseries query doesn't match any time series sets at all. This is seen as in invalid request and will result in a HTTP 400 response code.
The following are examples of use cases where this might occur:
- query parameters don't occur in filter. For example: the default filter has subfilters: filterA and filterB. filterA contains timeseries sets with module instance id moduleInstanceA and filterB contains timeseries sets with module instance id moduleInstanceB. If a timeseries query is done with parameters: filterId=filterA and moduleInstanceId=moduleInstanceB, this will return in a HTTP 400 response
- no timeseries for creation period. For example: if a query is using startCreationTime and endCreationTime and no time series have been produced during that period, this is seen as an invalid request and a HTTP 400 response is returned.
availability of new timeseries
When new timeseries have been created, it can take some time before they can be found by the WebServices. The web services updates its indexes every second (every five seconds before 2023.01). Once the indexes have been updated, newly created time series can be found. So it typically can take a few seconds before newly created time series can be found.
Example request
curl "http://localhost:8080/FewsWebServices/rest/fewspiservice/v1/timeseries?filterId=Netherlands&moduleInstanceIds=ImportObserved&startTime=2013-01-01T00:00:00Z&endTime=2014-01-01T00:00:00Z&convertDatum=false&useDisplayUnits=false&showThresholds=true&omitMissing=true&onlyHeaders=false&showEnsembleMemberIds=false&documentVersion=1.23&forecastCount=1"

Example request
curl "http://localhost:8080/FewsWebServices/rest/fewspiservice/v1/timeseries/grid?documentFormat=PI_JSON&layers=Temp_forecast_nwp&x=-121480.85450867479&y=6072939.872066073&startTime=2020-01-08T01:00:00.000Z&endTime=2020-01- 08T01:00:00.000Z&bbox=-1558755.612890017,4979850.04379049,1623657.8112034467,6709422.556884765"
WMS Test page
This timeSeries grid functionality can also be tested using the WMS service test page. Right clicking on a grid cell, will show a popup that will show the value of the grid cell for the current time step. When clicking on the PI Service URL the PI Request that was used to determine the current value, will be opened.
Example PI-XML and JSON response
See the timeseries endpoint for examples.
3D grids elevation and vertical profiles
For 3D grids the elevation parameter can be used to get the timeseries of a grid cell at a specified elevation (for example to get the water temperature at a specific water depth). On the WMS testing page this functionality can be tested by right clicking on a grid cell. The vertical slider on the left can be used to specify the elevation that should be used. When selecting the "Grid time series" option, a popup with the PI service URL will be generated that will get the timeseries for a grid cell at the selected elevation.
An example request with elevation:
http://localhost:8080/FewsWebServices/rest/fewspiservice/v1/timeseries/grid?documentFormat=PI_JSON&layers=kzn_temperature&x=3496535.421877103&y=-3484305.4973514746&startTime=2010-04-15T00:00:00.000Z&endTime=2010-04-15T00:00:00.000Z&bbox=3272727.803058107,-3739299.4237108226,3835304.3312370046,-3372401.6879419754&_=1602068760367&importFromExternalDataSource=false&elevation=10.453057
It is also possible to get a vertical profile for 3D data. On the WMS testing page this functionality can be tested by right clicking on a grid cell. When selecting the "Vertical Profile" option, a popup with the PI service URL will be generated that will get the timeseries of all elevations for a grid cell at the selected timestep. This is achieved by passing the showVerticalProfile=true parameter. It is possible to request vertical profiles for more than one time step by using the startTime and endTime.
An example request to get the vertical profile for one time step:
http://localhost:8080/FewsWebServices/rest/fewspiservice/v1/timeseries/grid?documentFormat=PI_JSON&layers=kzn_temperature&x=3516714.7973443894&y=-3506319.361497606&startTime=2010-04-15T00:00:00.000Z&endTime=2010-04-15T00:00:00.000Z&bbox=3272727.803058107,-3739299.4237108226,3835304.3312370046,-3372401.6879419754&_=1602068935896&importFromExternalDataSource=false&showVerticalProfile=true
The PI response of profiles will contain domain axes. In this example the water_depth is the domain axis and the different elevations are reported in the domainAxisValues.

POST timeseries (2017.02)
Write timeseries data to the FEWS system using the timeseries sets defined by the filters. The timeSeries are stored in the piTimeSeriesXmlContent.
The timeseries you post to the rest service should match one of the time series sets in the default filter or one of its sub filters. To make sure you only write time series for a specific filter, you can pass a filterId with the POST request. Only timeseries that have timeseries sets that are configured in that filter (or one of its sub filters) will be accepted. If no filterId is used, all time series will be accepted that are configured in the default filter. Writing the time series works similar to importing time series using the pi.xml format using the "PI" import type. See also: Delft-Fews Published Interface timeseries Format (PI) Import
The 'convertDatum' argument is to allow timeseries that support a datum to have their values converted to a value relative to the location height. If values are already relative to location then enter FALSE or omit.
In case a time series already exists in the database, the time series will be overwritten by the ones that are posted. For forecast time series with different forecastDates a new time series will be added. The latter can be achieved by providing a forecastDate element in the POST request, e.g. <forecastDate date="2013-01-01" time="00:00:00"/>.
N.B.: by default POST operations are disabled in the Delft-FEWS WebServices and have to be explicitly enabled by setting the READONLY_MODE to false in the FewsPiService.properties. See also: FEWS Web Services Configuration FewsPiService.properties (deprecated since 2022.02).
Request parameters
filterId (string, optional): Filter id for when the input timeseries maps to multiple internal timeseries. Within the scope of the filter the input timeseries should only map to one internal timeseries. When no filterId is specified, the default filter applies.
convertDatum (boolean, optional): Convert values from relative location height to absolute height values
Body parameters
piTimeSeriesXmlContent (xml string, required): PiTimeseries xml file encoded in the 'application/x-www-form-urlencoded Content-Type. Example of a piTimeSeriesXmlContent (unencoded):

N.B. The SOAP Web Service has support for posting timeSeries as binary data using the piTimeSeriesBinaryContent. This is NOT support in this REST service of the PI Service.
- When sending in a set of timeseries that correspond to (e.g.) a completed forecast over multiple locations, it is not necessary to POST each location separately, the entire set be sent in one TimeSeries XML document with multiple series.
- There is no option in the REST Web Service to do any aggregation or transformation.
Response
- Diag PI xml response with all diagnostic output.
Example request
The following example shows how timeSeries can created using the POST method. Take note that the TimeSeries have to be posted in PI XML Format in the body of the POST request using the piTimeSeriesXmlContent key. The value is the content of the PI XML Timeseries in application/x-www-form-urlencoded format.
