pointLineD {SpatialGraph}

Euclidean distance from a set of points to a line segment

Description

pointLineD returns a list with a number of components from a points to line segment analysis

Usage

pointLineD(xy, xyp)

Arguments

xy

2 x 2 [x,y] matrix defining the start and end of the segment

xyp

p x 2 [x,y] matrix with a point set

Details

pointLineD conduct a detailed points to segment distance analysis, returned as a list

Value

A list with the input components xy and xyp, and the aditional components: d, point-line distance (distance between the points in xyp and their perpendicular projections of the line); dc, diferential chainage over [x0,y0] (> 0 if the projection goes in the segment direction); cross, boolean vector indicating whether the perpendicular projection of the points crosses the segment, or not
