Detailed Description

A class for writing attributes from an HDF-EOS2 file.

This class contains functions that generates SDS attributes and Vdata attributes. Since HDF-EOS2 library API don't have access to field attributes, we need to use generic HDF4 API.

For most HDF-EOS2 files, Grid doesn't use Vdata. Swath has Vdata but fields with Vdata normally contain attributes. However, we still check and provide ways to generate attributes.

Member Function Documentation

bool HE2CF::close

(

void

)

closes the opened file.

Definition at line 1043 of file HE2CF.cc.

string HE2CF::get_metadata	(	const string &	metadataname,
		bool &	suffix_is_num,
		vector< string > &	non_num_names,
		vector< string > &	non_num_data
	)

retrieves the merged metadata.

Definition at line 1059 of file HE2CF.cc.

bool HE2CF::open	(	const string &	filename,
		const int	sd_id,
		const int	file_id
	)

openes HDF4 file.

Definition at line 1068 of file HE2CF.cc.

void HE2CF::set_DAS

(

DAS *

das

)

sets DAS pointer so that we can bulid attribute tables.

Here is the call graph for this function:

bool HE2CF::write_attribute	(	const string &	gname,
		const string &	fname,
		const string &	newfname,
		int	n_groups,
		int	fieldtype
	)

writes attribute table into DAS given grid/swath name and its field name.

Definition at line 1098 of file HE2CF.cc.

bool HE2CF::write_attribute_coordinates	(	const string &	varname,
		string	coord
	)

writes coordinates attribute into varname attribute table.

This attribute plays an essential role for two dimensional coordinate system like Swath.

Definition at line 1230 of file HE2CF.cc.

bool HE2CF::write_attribute_FillValue	(	const string &	varname,
		int	type,
		float	val
	)

writes _FillValue attribute into varname attribute table.

This attribute plays an essential role for two dimensional coordinate system like Swath.

Here is the call graph for this function:

bool HE2CF::write_attribute_units	(	const string &	varname,
		string	units
	)

writes units attribute into varname attribute table.

Any existing units attribute will be overwritten by this function.
