ExtractBoundary() [1/2]

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

static

ExtractBoundary() [2/2]

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
	[output]	bdry Output array containing the boundary values of a. The number of elements copied to bdry is 2 * nx + 2 * ny - 4.

ShiftLon() [1/3]

static void VAPoR::GeoUtil::ShiftLon ( float *  first, float *  last, double  bound = 360.0  )

static

ShiftLon() [2/3]

static void VAPoR::GeoUtil::ShiftLon ( vector< double >::iterator  first, vector< double >::iterator  last, double  bound = 360.0  )

static

ShiftLon() [3/3]

static void VAPoR::GeoUtil::ShiftLon ( vector< float >::iterator  first, vector< float >::iterator  last, double  bound = 360.0  )

static

Shift a container of longitude values so that all values are in the range [-bound .. bound]

UnwrapLongitude() [1/3]

static void VAPoR::GeoUtil::UnwrapLongitude ( float *  first, float *  last  )

static

UnwrapLongitude() [2/3]

static void VAPoR::GeoUtil::UnwrapLongitude ( vector< double >::iterator  first, vector< double >::iterator  last  )

static

UnwrapLongitude() [3/3]

static void VAPoR::GeoUtil::UnwrapLongitude ( vector< float >::iterator  first, vector< float >::iterator  last  )

static

Unwrap any wrapped longitued values

Iteratively adds 360.0 to each value in a container that is less than the first value until the new value is greater than the first.
