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:

The Grids import will be defined here.

Configuring the import

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

ImportNetcdf_Grid 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">

			<readWriteMode>add originals</readWriteMode>
			<synchLevel>6</synchLevel>
		</timeSeriesSet>
	</import>
</timeSeriesImportRun>

An example fo the IdMapping used for the NETCDF-CF_GRID import is shown below.

IdImportNetCDF 1.00 default.xml
<idMap version="1.1" 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/idMap.xsd">
	<map internalParameter="Snelheid.u.F0" internalLocation="hmcn_zeedelta" externalParameter="velocity" externalLocation="hmcn_zeedelta"/>
</idMap>

When importing grids in the FEWS database it is required to configure the grid characteristics in the grids.XML file. The grid characteristics must be similar to the grid imported from the NetCDF file.

Grids 1.00 default.xml
	<regular locationId="hmcn_zeedelta">
		<description>HMCN Zeedelta Model</description>
		<rows>101</rows>
		<columns>101</columns>
		<geoDatum>Rijks Driehoekstelsel</geoDatum>
