Introduction

Export a grid frame to ESRI Shapefile

The format and content of this export is equivalent to exporting a grid frame from the spatial display window using the debug menu (F12)

The ID of this serializer is 'grid2shp'. 

Example module configuration

<timeSeriesExportRun 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/timeSeriesExportRun.xsd">
	<export>
		<general>
			<exportType>grid2shp</exportType>
			<folder>$EXPORT_FOLDER$</folder>
			<exportFileName>
				<name>PQPF_GRIB2</name>
				<prefix>
					<currentTimeFormattingString>yyyyMMddHHmmss</currentTimeFormattingString>
				</prefix>
			</exportFileName>
			<exportMissingValue>-999</exportMissingValue>
		</general>
		<timeSeriesSet>
			<moduleInstanceId>ImportGrids_PQPF</moduleInstanceId>
			<valueType>grid</valueType>
			<parameterId>QPF</parameterId>
			<qualifierId>PQPF50</qualifierId>
			<locationId>PQPF_GRIB2</locationId>
			<timeSeriesType>external forecasting</timeSeriesType>
			<timeStep multiplier="6" unit="hour"/>
			<relativeViewPeriod end="6" start="6" unit="hour"/>
			<readWriteMode>read only</readWriteMode>
		</timeSeriesSet>
	</export>
</timeSeriesExportRun>

Notes:

1) The 'grid2shp' serializer can only output one time step so in case the grid is part of a timeseries the relativeViewperiod needs to be set to select a range of which only the first timestep will be used.

2) A prefix or suffix can be added to the filename using a time formatting string as in the given example using either the <currentTimeFormattingString> or <timeZeroFormattingString>.

3) The exportMissingValue can be used to replace the given missing values by NaN (Not A Number) values to indicate that there is no valid data, ArcGIS will display such records as '0' instead of -999 in this example.
