Function Documentation

yac_interp_method_spmap_new()

struct interp_method * yac_interp_method_spmap_new	(	double	spread_distance,
		double	max_search_distance,
		enum yac_interp_spmap_weight_type	weight_type,
		enum yac_interp_spmap_scale_type	scale_type,
		double	src_sphere_radius,
		double	tgt_sphere_radius )

Constructor for a interpolation method of type interp_method_spmap
This method searches for each unmasked source point the closest unmasked target point.
If the maximum search distance is > 0.0, only target points that are within this distance from the source points are being considered. If spread_distance is > 0.0, the method uses the previously found target points as a starting point. Around each starting point, a bounding circle is generated. Afterwards for each starting point all target cells whose bounding circles intersect with the generated one are put into a list. Out of this list all target cells connected directly or indirectly through other cells from this list to the target cell of the starting are selected for the interpolation. Then a weighting method is applied to the selected target cells to generate the weights. Afterwards the weights are scaled.

Parameters

[in]	spread_distance	spreading distance
[in]	max_search_distance	maximum search distance
[in]	weight_type	weighting type
[in]	scale_type	scaling type
[in]	src_sphere_radius	sphere radius used for source cell area computation
[in]	tgt_sphere_radius	sphere radius used for target cell area computation

Remarks

the unit for the spread and maximum search distance is Radian
