Snap points to lines — snapPointsToLines2 • spNetwork

Snap points to their nearest lines (edited from maptools)

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

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.
...: unused

Value

A feature collection of points with the projected geometries

Examples

# reading the data
data(mtl_network)
data(bike_accidents)
mtl_network$LineID <- 1:nrow(mtl_network)
# snapping point to lines
snapped_points <- snapPointsToLines2(bike_accidents,
    mtl_network,
    "LineID"
)
