(

struct yac_interp_method_dnn_config

config

)

Creates a distance-nearest-neighbour (DNN) interpolation method.

DNN interpolates target points using all source points located within a given search distance (bounding circle) around each target point.

The search distance can be either:

• A fixed value in radians (YAC_INTERP_DNN_SEARCH_DISTANCE_FIXED)
• Computed from the target cell area (YAC_INTERP_DNN_SEARCH_DISTANCE_CELL_AREA): The polar angle of a spherical cap with the same area as the target cell, multiplied by search_distance_scale.

Parameters

[in]

config

configuration for the interpolation method

Returns

interpolation method

Remarks

Target points for which less than n_min (default: 1) source points are found within the search distance will not be interpolated by this method.

When using YAC_INTERP_DNN_SEARCH_DISTANCE_CELL_AREA, the target field location must be YAC_LOC_CELL.
