snapPointsToLines2: Snap points to lines

Description

Snap points to their nearest lines (edited from maptools)

Usage

snapPointsToLines2(points, lines, idField = NA, snap_dist = Inf, ...)

Value

A feature collection of points with the projected geometries

Arguments

points

A feature collection of points

lines

A feature collection of linestrings

idField

The name of the column to use as index for the lines

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. The default value is Inf. The function will raise an error if some points are too far from a line.
