Snap Stream Measure to Point

fwa_snap_stream_measure_to_point.Rd

Assigns closest stream measure in m to each spatial point. If the blue line key (blk) is missing then it is also assigned together with the distance to the stream (distance_to_stream) in m.

Usage

fwa_snap_stream_measure_to_point(x, streams, ...)

Arguments

x

An sf object of spatial points with optional integer column blk.

streams

An sf object of spatial linestrings with blk column.

...

Additional columns to group by when assigning.

Value

An updated version of x with integer columns blk and stream_measure and numeric column distance_to_stream.
