polyline

A polyline is a type of geometryA geometry is a geometric shape, such as a point, polyline, or polygon, that contains one or more coordinates and a spatial reference.Learn more containing ordered pointA point is a type of geometry containing a single set of x,y coordinates and a spatial reference.Learn more coordinates and a spatial referenceA spatial reference is a set of parameters, typically defined by a WKID, that define the coordinate system and spatial properties for geographic data. Applications use a spatial reference to correctly display the position of geographic data in a map or scene.Learn more. 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.
