# gml:boundedBy

### Diagram

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

### Description {#desc}

Contains a description of the boundaries of the viewport of a geo object on the map.

The viewport for most geo objects is the minimal rectangle around the object. The viewport is set by two geo points, the coordinates of which are contained in the [gml:lowerCorner](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/gml-lowerCorner.md) and [gml:upperCorner](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/gml-upperCorner.md) tags.

If the element is specified in the [repr:View](https://yandex.ru/dev/maps/ymapsml/doc/en/ref/reference/representation-View.md) tag, the center of the set viewport defines the initial center of the map. The zoom level is selected so that the entire viewport is visible in the map window, when possible.

### Contains:
