Overview

Imports grid time series data from NetCDF files which comply to the CF standard. 

Import Configuration

An example of the CMEMS import will be given here. This example is configured to import 2D Hourly grids for the last 24 hours.

Make sure the parameters that are needed are added to the URL:
The following parameters are available:

Id Map Configuration

An example of 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">
	<parameter internal="Wind.u" external="uo"/>
	<parameter internal="Wind.v" external="uv"/>
</idMap>

Grids Configuration

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="CMEMS_2D">
		<rows>241</rows>
		<columns>265</columns>
		<geoDatum>WGS 1984</geoDatum>
		<firstCellCenter>
			<x>43</x>
			<y>28</y>
		</firstCellCenter>
		<xCellSize>0.0833</xCellSize>
		<yCellSize>0.0833</yCellSize>
	</regular>
