nearest_lines {spNetwork} | R Documentation |
Nearest line for points
Description
Find for each point its nearest LineString
Usage
nearest_lines(points, lines, snap_dist = 300, max_iter = 10)
Arguments
points |
A feature collection of points |
lines |
A feature collection of linestrings |
snap_dist |
A distance (float) given to find for each point its nearest line in a spatial index. A too big value will produce unnecessary distance calculations and a too short value will lead to more iterations to find neighbours. In extrem cases, a too short value could lead to points not associated with lines (index = -1). |
max_iter |
An integer indicating how many iteration the search algorithm must perform in the spatial index to find lines close to a point. At each iteration, the snap_dist is doubled to find candidates. |
