Network functions dist_info
- dist_info(arcs, points, [optional] maxSqrDist)
The dist_info(arcs, points) function is used to get the distance between the point from the points and the CutPoint on the arc/polygon outline from the arcs. This is the same as the dist attribute from the connect_info function.
The arcs should contain unique geometries. Use the unique function to make a domain unit with unique geometries.
- data items arcs and points with fpoint or dpoint value type
- data item arcs with composition type arc or polygon. Be aware that if you connect points to polygons, use a split_polygon to avoid connecting to segments that separate different rings (lakes or islands) in a polygon.
The values type of arcs and points must match.
