Lines are also one of the basic types of GIS layers. Lines actually consist of interconnected points in a defined order. Therefore each line is distinguished by its “start” and “end” points; not simply two “ends” as it might appear. 

A line layer usually represents objects with much greater length than width. Typical examples are paths, roads, water streams… 

Lines may also be described by a number of attributes. 

Any of the line layers may serve as input to polygonization (see Polygonization), i.e. any line may become the border of a polygon.
