typedef short int felt::word

A felt block "word" - 2 bytes.

Function Documentation

std::ostream& felt::contentSummary	(	std::ostream &	out,
		const FeltGridDefinition &	grid
	)

template<typename T >

T felt::get ( word w )

boost::array<float, 6> felt::gridParameters	(	int	gridType,
		int	xNum,
		int	yNum,
		int	a,
		int	b,
		int	c,
		int	d,
		const std::vector< short int > &	extraData
	)

retrieve the 6 gridparameters from the felt-data

Parameters

gridType	id of the grid, (header[8] < 1000) ? header[8] : (int) header[8] / 1000
xNum	number of points in x-direction, header[9]
yNum	number of points in x-direction, header[10]
a	used for different depending on gridType, header[14]
b	used for different depending on gridType, header[15]
c	used for different depending on gridType, header[16]
d	used for different depending on gridType, header[17]
extraData	data at the end of the data-region, used for high resolution information (header[8] < 1000) ? 0 : header[8] % 1000

std::string felt::gridParametersToProjDefinition	(	int	gridType,
		const boost::array< float, 6 > &	gridPars
	)

convert the libmi-gridparameters to proj4 strings

Parameters

gridType	type defining the projection (1..6)
gridPars	array containing libmi's six gridparameters

bool felt::isUndefined ( word w )

inline

Is the given word a "missing" value? This means that there exist no valid data for the given point
