Polyline
A one-dimensional vector feature composed of straight line segments, used to represent linear features like roads or rivers (inferred from standard GIS usage).
What does a Polyline represent?
In GIS, a polyline is a linear feature made up of one or more segments of connected straight lines. Roads, rivers, pipelines, trails, and other geographic features with length but no area are modelled using the complete form, which is made up of two or more ordered points (vertices) for each segment.
Important Features:
Polylines do not encompass an area like polygons do.
Both simple (one segment) and complex (many segments) are possible.
Name, length, and feature type are examples of attribute data that are stored in each polyline.
The shape and trajectory of linear geographic characteristics across space are captured by a polyline, a flexible vector data type.

In GIS, a polyline is a kind of vector data that is used to depict linear objects like utility lines, rivers, and roadways. It is made up of interconnected points known as vertices that form either straight or curved lines. In geographic information systems, polylines are crucial for network mapping, route analysis, and spatial relationship modelling.
A connected series of line and arc segments handled as a single object is called a polyline in CAD. It is perfect for designing roads, boundaries, and other linear features because it enables exact, continuous designs. Polylines provide freedom over individual lines and are simple to alter, scale, and style.
An arrangement of linked line segments that depict routes or paths on a map is called a Google Maps polyline. In web and mobile applications, it's frequently used to show roads, trails, or bespoke routes, enabling developers to see movement patterns, boundaries, and navigation. For improved map clarity, polylines can be altered in terms of colour, width, and pattern.
A polyline is an unenclosed set of linked line segments that is used to depict linear elements such as rivers, roads, or trails. In contrast, a polygon is a closed shape made up of several lines that can be used to represent places like parks, lakes, or property parcels. In essence, polygons depict areas, and polylines depict pathways.
