Overview

This import is available in DELFT-FEWS versions after 28-10-2009 (FEWS version 2009.02)

Imports data from NetCDF files which comply to the CF standard.
More information about the cf standards can be found at: http://cf-pcmdi.llnl.gov/conformance/requirements-and-recommendations/1.4

There are three types of NetCDF-CF imports which can be defined:

  • Time series (NETCDF-CF_TIMESERIES)
  • Profiles (NETCDF-CF_PROFILE)
  • Grids (NETCDF-CF_GRID)

Configuring the import

An example of the NETCDF-CF_TIMESERIES import will be given here.

ImportNetcdf_Timeseries 1.00 default.xml
<?xml version="1.0" encoding="UTF-8"?>
<timeSeriesImportRun 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/timeSeriesImportRun.xsd">
	<import>
		<general>
			<importType>NETCDF-CF_TIMESERIES</importType>
			<folder>$IMPORT_FOLDER$/NETCDF</folder>
			<failedFolder>$IMPORT_FAILED_FOLDER$</failedFolder>
			<backupFolder>$IMPORT_BACKUP_FOLDER$</backupFolder>
			<idMapId>IdImportNetCDF</idMapId>
		</general>
		<timeSeriesSet>
			<moduleInstanceId>ImportNetcdf_Timeseries</moduleInstanceId>
			<valueType>scalar</valueType>
			<parameterId>Q.udm</parameterId>
			<locationSetId>DMFlowPoints</locationSetId>
			<timeSeriesType>external historical</timeSeriesType>
			<timeStep unit="nonequidistant"/>
			<readWriteMode>add originals</readWriteMode>
		</timeSeriesSet>
	</import>
</timeSeriesImportRun>

An example of the IdMapping used for the NETCDF-CF_TIMESERIES import will be given below.
In this example, the mapped locations correspond to the locations of the locatiesSet as defined above in the ImportNetcdf_Timeseries.xml.

Note that in the IdMapping of the parameters and locations, the external name must match the variable and location names as used by the netcdf file exactly (case sensitive).
