◆ IL_vector_input_data_2d()

int IL_vector_input_data_2d	(	struct interp_params *	params,
		struct Map_info *	Map,
		int	field,
		char *	zcol,
		char *	scol,
		struct tree_info *	info,
		double *	xmin,
		double *	xmax,
		double *	ymin,

Insert into a quad tree

Inserts input data inside the region into a quad tree. Also translates data. Returns number of segments in the quad tree.

As z values may be used (in Map):

z coordinates in 3D file -> field = 0
categories -> field > 0, zcol = NULL
attributes -> field > 0, zcol != NULL

Parameters

params	interpolation parameters
Map	input vector map
field	category field number
zcol	name of the column containing z values
scol	name of the column containing smooth values
info	quadtree info
n_points	number of points used for interpolation
dmax	max distance between points
