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_PROFILE import will be given here.

ImportNetcdf_Profile 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">

			<failedFolder>$IMPORT_FAILED_FOLDER$</failedFolder>
			<backupFolder>$IMPORT_BACKUP_FOLDER$</backupFolder>
			<idMapId>IdImportNetCDF</idMapId>

			<timeStep unit="day" multiplier="1"/>
			<readWriteMode>add originals</readWriteMode>
		</timeSeriesSet>
	</import>
</timeSeriesImportRun>

An example of the IdMapping used for the NETCDF-CF_PROFILE 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, the external name must match the variable names as used by the netcdf file exactly (case sensitive).
The locations that are mapped refer to branch id's which are defined in the Branches.xml.

</idMap>

An example of the branches file is shown below.

The locationSetId used by the ImportNetcdf_Profile.xml must contain the branches defined in the above IdMapping.
