The following data will be read by the importer:

An astronomical tide timeSeries for the defined timesteps. The location is based on the header (06514 in the following example). The parameter is based on the first column of the values (054003 in the following example)
A deterministic skew surge forecast timeSeries for the defined timesteps. The location is based on the header (06514 in the following example). The parameter is based on the first column of the values (054004 in the following example). To differentiate the deterministic forecast with the control forecast, a qualifier is used: "0010920".
A control skew surge forecast timeSeries for the defined timesteps. The location is based on the header (06514 in the following example). The parameter is based on the first column of the values (054004 in the following example). To differentiate the deterministic forecast with the control forecast, a qualifier is used: "0010921".
Ensembles with skew surge forecast timeSeries for the defined timesteps. The location is based on the header (06514 in the following example). The parameter is based on the first column of the values (054004 in the following example). To differentiate the deterministic forecast with the control forecast, a qualifier is used: "0010921". Ensembles are marked with an ensembleId (001091 in the following example) and an ensemble member index (1 .. 50).
Timesteps are determined by the times specified with the Astronomical tide. Times are given in HHH:mm format.

Configuring the Import

To make the importer known to FEWS, the import module has to be declared in the moduleInstanceDescriptors.xml in the RegionConfigFiles directory of the FEWS configuration:

Code Block

	xml
	xml

<?xml version="1.0" encoding="UTF-8"?>
<moduleInstanceDescriptors xmlns="http://www.wldelft.nl/fews"
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
		xsi:schemaLocation="http://www.wldelft.nl/fews
		http://fews.wldelft.nl/schemas/version1.0/moduleInstanceDescriptors.xsd" version="1.0">
...
	<moduleInstanceDescriptor id="WmoBufrAsciiImportWmoBufrAscii">
		<moduleId>TimeSeriesImportRun</moduleId>
	</moduleInstanceDescriptor>
...
</moduleInstanceDescriptors>

An example of the WmoBufrAscii import (filename: ImportWmoBufrAscii.xml) configuration will be given here. The importType is named WmoBufrAscii which should be configured in the general section of the import.

The IdMapping configuration wmoBufferAsciiMapIdBUFR_dcsmv5eps_import.xml is is needed to maps the internal FEWS Id's to the WmoBufferAscii Id's. An example IdMapping file importer is shown below.:
