Member Function Documentation

static CartesianGrid2D code::DataConverter::convertToCartesianGrid2D	(	const RadialSet &	rs,
		const PolarCartesianLookup &	lookup
	)			[static]

Efficiently converts the given radial set into a CartesianGrid2D using precomputed values in the lookup array.

The polar-to-cartesian mapping is a simple nearest-neighbor method.

Parameters:

	rs	the radial set with the data
	lookup	Precomputation results

static Image<float> code::DataConverter::convertToImage	(	const RadialSet &	rs,
		const PolarCartesianLookup &	lookup
	)			[static]

Efficiently converts the given radial set into an Image using precomputed values in the lookup array.

The location, time, etc. are lost in this conversion. What is obtained is a cartesian grid suitable for image processing tasks. The polar-to-cartesian mapping is a simple nearest-neighbor method.

Parameters:

	rs	the radial set with the data
	lookup	Precomputation results

static Image<float> code::DataConverter::convertToImage	(	const RadialSet &	rs,
		float	scale = 1.0,
		int	accuracy = 10
	)			[static]

Converts the given radial set into an Image.

See the convertToImage that takes a PolarCartesianLookup for a more efficient method.

The location, time, etc. are lost in this conversion. What is obtained is a cartesian grid suitable for image processing tasks. The polar-to-cartesian mapping is a simple nearest-neighbor method.

Parameters:

	rs	the radial set with the data
	scale	A value of scale < 1 indicates a low-resolution image while scale > 1 indicates a zoomed in image. The extent of the image is that of the radial set.
	accuracy	How accurate do you want the conversion to be? Larger numbers denote greater accuracy. Use at least 5. This is the accuracy of the polar-to-cartesian mapping.

static LatLonGrid code::DataConverter::convertToLatLonGrid	(	const RadialSet &	llgrid,
		const PolarLatLonLookup &	lookup
	)			[static]

Resamples the given LatLonGrid and fits the nearest data value into a PolarGrid whose radar location and resolutions and sizes are given by the lookup.

WARNING! This is a 2D conversion; for 3D conversion (recommended), you should use w2merger or its classes.

static PolarGrid code::DataConverter::convertToPolarGrid	(	const LatLonGrid &	llgrid,
		const LatLonPolarLookup &	lookup
	)			[static]

Resamples the given LatLonGrid and fits the nearest data value into a PolarGrid whose radar location and resolutions and sizes are given by the lookup.
