Detailed Description

BESTransmitter class named "geotiff" that transmits an OPeNDAP data object as a geotiff file.

The GeoTiffTransmitter transforms an OPeNDAP DataDDS object into a geotiff file and streams the new (temporary) geotiff file back to the client.

Constructor & Destructor Documentation

GeoTiffTransmitter::GeoTiffTransmitter ( )

Construct the GeoTiffTransmitter, adding it with name geotiff to be able to transmit a data response.

The transmitter is created to add the ability to return OPeNDAP data objects (DataDDS) as a geotiff file.

The OPeNDAP data object is written to a geotiff file locally in a temporary directory specified by the BES configuration parameter FONg.Tempdir. If this variable is not found or is not set then it defaults to the macro definition FONG_TEMP_DIR.

Note: The mapping from a 'returnAs' of "geotiff" to this code is made in the FONgModule class.

void GeoTiffTransmitter::send_data_as_geotiff	(	BESResponseObject *	obj,
		BESDataHandlerInterface &	dhi
	)

static

The static method registered to transmit OPeNDAP data objects as a netcdf file.

This function takes the OPeNDAP DataDDS object, reads in the data (can be used with any data handler), transforms the data into a netcdf file, and streams back that netcdf file back to the requester using the stream specified in the BESDataHandlerInterface.

Parameters

obj	The BESResponseObject containing the OPeNDAP DataDDS object
dhi	BESDataHandlerInterface containing information about the request and response

Exceptions

BESInternalError if the response is not an OPeNDAP DataDDS or if there are any problems reading the data, writing to a netcdf file, or streaming the netcdf file
