static void VAPoR::GeoUtil::ExtractBoundary	(	const float *	a,
		int	nx,
		int	ny,
		float *	bdry
	)

static

Extract boundary points from a 2D grid

This method walks a 2D array, a, in counter-clockwise order, visiting each boundary grid point exactly once, copying the value to the array bdry. A total of 2*nx + 2*ny - 4 grid points are copied.

Parameters

[in]	a	An 2D array dimensioned `nx` by `ny`
[in]	nx	dimension of fastest moving coordinate
[in]	ny	dimension of slowest moving coordinate

static void VAPoR::GeoUtil::ExtractBoundary	(	const double *	a,
		int	nx,
		int	ny,
		double *	bdry
	)

static

static void VAPoR::GeoUtil::LatExtents	(	const float *	lon,
		int	nx,
		int	ny,
		float &	latsouth,
		float &	latnorth
	)

static

Calculate south-most and nort-most extents for a grid of latitude values

Note: Assumes valid coordinates are in the range -180 to 180

Parameters

[in]	lon	A structured 2D grid of latitude coordintes in degrees
[in]	nx	dimension of fastest moving coordinate
[in]	ny	dimension of slowest moving coordinate
[out]	latsouth	south-most latitude coordinate
[out]	latnorth	north-most latitude coordinate

static void VAPoR::GeoUtil::LatExtents	(	const double *	lon,
		int	nx,
		int	ny,
		double &	latsouth,
		double &	latnorth
	)

static void VAPoR::GeoUtil::LonExtents	(	const float *	lon,
		int	nx,
		int	ny,
		float &	lonwest,
		float &	loneast
	)

static

Calculate west-most and east-most extents for a grid of longitudinal values

Note: If the input values wrap (cross 0 if coordinates run from 0 to 360, or cross 180 if coordinates run from -180 to 180) the returned values may be shifted by 360 degrees such that lonwest < loneast

Parameters

[in]	lon	A structured 2D grid of longitude coordintes in degrees
[in]	nx	dimension of fastest moving coordinate
[in]	ny	dimension of slowest moving coordinate
[out]	lonwest	west-most longitude coordinate
[out]	loneast	east-most longitude coordinate

static void VAPoR::GeoUtil::LonExtents	(	const double *	lon,
		int	nx,
		int	ny,
		double &	lonwest,
		double &	loneast
	)

static

static void VAPoR::GeoUtil::LonExtents	(	const float *	lon,
		int	nx,

		float &	loneast
	)

static

Calculate west-most and east-most extents for a grid of longitudinal values

Note: If the input values wrap (cross 0 if coordinates run from 0 to 360, or cross 180 if coordinates run from -180 to 180) the returned values may be shifted by 360 degrees such that lonwest < loneast

Parameters

[in]	lon	A 1D grid of longitude coordintes in degrees
[in]	nx	dimension of grid
[out]	lonwest	west-most longitude coordinate
[out]	loneast	east-most longitude coordinate
