# Module: RGeo::Feature::Line

- Extended by:
- Type

- Includes:
- LineString

- Included in:
- Cartesian::LineImpl, Geographic::ProjectedLineImpl, Geographic::SphericalLineImpl, Geos::CAPILineImpl, Geos::FFILineImpl

- Defined in:
- lib/rgeo/feature/line.rb

## Overview

## SFS 1.1 Description

A Line is a LineString with exactly 2 Points.

## Notes

Line is defined as a module and is provided primarily for the sake of documentation. Implementations need not necessarily include this module itself. Therefore, you should not depend on the kind_of? method to check type. Instead, use the provided check_type class method (or === operator) defined in the Type module.
