A polyline is a type of geometry containing ordered point coordinates and a spatial reference. A polyline typically contains a single ordered sequence of points, but can contain multiple sequences that represent individual parts of the entire polyline (these sequences are sometimes referred to as parts, paths, or segments). Each point coordinate is expressed as x,y values but can optionally also include a z value for elevation and/or a numeric m value, commonly used for linear referencing.
