This function calculates the coordinates of the nearest point on a line to a given point. This function does not work with geographic coordinates.

nearestPointOnLine(coordsLine, coordsPoint)

Arguments

coordsLine

Matrix with coordinates of line vertices. Each row represents a vertex.

coordsPoint

A vector representing the X and Y coordinates of the point.
