GET timeseries/grid (2019.02)

The timeseries/grid endpoint is intended to be used together with the Delf-FEWS WMS service. Every layer that is provided by the WMS service, can be used with this endpoint. See also FEWS Web Mapping Service with time support (WMS-T).

Returns a pi timeseries xml file containing the timeseries data from a grid cell for a request period. The grid is specified by passing a layerId. The grid cell is determined by specifying a x and y coordinate. Currenly only WGS84 is supported where x is the longitude and y the latitude coordinate. Both a startTime and endTime are required.

Request parameters

  • convertDatum (boolean): Convert values from relative location height to absolute height values. 
  • documentVersion (string, 1.9 or up): File format version (optional). For example: 1.23
  • documentFormat (string): PI_XML (default) or PI_JSON
  • endTime (dateTime: yyyy-MM-ddTHH:mm:ssZ): End time of search period that looks for timeseries values that lie within this period.
  • layers (string, required): layerd id (currently, only one layer is supported) that matches the gridPlot id as configured in the gridDisplay. Every gridPlot that has been configured in the grid display configuration represents a WMS layer. For more information, see the WMS Service documentation: FEWS Web Mapping Service with time support (WMS-T)
  • omitMissing (boolean): Toggle omitting or returning of missing values in response
  • onlyHeaders (boolean): Toggle to return only header information or also data
  • onlyForecasts (boolean): Toggle to return only forecast timeSeries (Since 2017.02)
  • onlyManualEdits (boolean): Toggle to return only manual edits.
  • 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 timeseries. Typically used in combination with onlyHeaders. Returns additional information about data availability of timeseries (Since 2015.01). 
    • firstValueTime: First time with a value in the timeSeries
    • lastValueTime: Last time with a value in the timeSeries
    • maxValue: Maximum value in the timeSeries
    • minValue: Minimum value in the timeSeries
    • valueCount: Number of values in the timeSeries
  • showThresholds (boolean): Option to toggle the returning of threshold information in the headers
  • showEnsembleMemberIds (boolean): Show ensemble member ids.
  • thinning (long): unit ms/pixel. Thinning is used to retrieve the visually interesting time steps of timeSeries. 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 timeSeries 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 bellow. Available in 2017.02 and from 2019.02
  • startTime (dateTime: yyyy-MM-ddTHH:mm:ssZ, required): Start time of search period that looks for timeseries values that lie within this period.
  • useDisplayUnits (boolean): Export values using display units.
  • importFromExternalDataSource (boolean, default true): import data from external data source (Archive). (since 2019.02)
  • x (double, required): Longitude of grid position on the map.
  • y (double, required): Latitude of the grid position on the map.

Response

  • Timeseries PI-XML or PI-JSON file content..

GET samples (2017.02)

Request parameters

  • documentVersion (string, 1.21 or up): File format version (optional). For example: 1.23
  • endCreationTime (dateTime: yyyy-MM-ddTHH:mm:ssZ): End time of search period that looks for creation time of samples. Note: creation time of samples is actually the creation time of the task that produced/imported these samples.
  • endTime (dateTime: yyyy-MM-ddTHH:mm:ssZ): End time of search period that looks for sample values that lie within this period.
  • filterId (string): Filter id.
  • locationIds (string): Subset of locations for which to retrieve samples. Repeat parameter for multiple location ids.
  • omitMissing (boolean): Toggle omitting or returning of missing values in response
  • onlyHeaders (boolean): Toggle to return only header information or also data
  • parameterIds (string): Subset of parameters for which to retrieve samples.
  • qualifierIds (string): Subset of qualifiers for which to retrieve samples.
  • sampleIds Subset of sample id's for which to retrieve samples. Repeat parameter for multiple samples ids.
  • startCreationTime (dateTime: yyyy-MM-ddTHH:mm:ssZ): Start time of search period that looks for creation time of samples. Note: creation time of samples is actually the creation time of the task that produced/imported these samples.
  • startTime (dateTime: yyyy-MM-ddTHH:mm:ssZ): Start time of search period that looks for sample values that lie within this period.

...

  • If no startCreationTime and endCreationTime have been set, the startTime and endTime are used to determine the search period.

  • yMax (string): upper y coordinate of the bounding box for which data should be generated

  • xCellSize (string): width of the cell size

  • yCellSize (string): height of the cell size

Response

  • The workflow indicated by the workflowId should generate a data-file (usually a netcdf-file). if the workfow has succesfully generated a netcdf-file, the response will be binary stream containing the generated file. If no file is generated an 500 error will be thrown.
