# gml:LineString

### Diagram

![](../_images/LineString.png)

### Description {#desc}

Specifies the "Polyline" type of geo object.

This tag indicates that a geo object is a polyline and contains a description of its points.

There are two ways to set the point coordinates of a polyline:

1. Using multiple [gml: pos](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/gml-pos.md) tags.
1. Using the [gml: posList](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/gml-posList.md) tag.

In the first case, the coordinates of each point are wrapped in a separate[gml: pos](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/gml-pos.md) tag; in the second case, they are listed in a more compact way within one [gml: posList](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/gml-posList.md) tag.

{% note tip %}

It is recommended to use the [gml: posList](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/gml-posList.md) tag for describing a polyline with a large number of points.
