# Site Model Repository

The [Site Model Repository](https://ivion-api.docs.navvis.com/latest/reference/interfaces/sitemodelrepositoryinterface.html) provides filters for finding buildings, floors, and rooms from a given point within a site model in NavVis IVION.

A Site Model is a three-dimensional, hierarchical model that clusters information by assigning meaningful names to clearly defined areas in the space of a Site. Each site model entity type may have a logical set of sub-entities, for example, a `BUILDING` site model entity type may contain `ROOM` types as its children.

## Getting a Floor from a Point

### Procedure

1. Use the [MainViewInterface](https://ivion-api.docs.navvis.com/latest/reference/interfaces/mainviewinterface.html) 3D cursor to obtain an arbitrary coordinate by calling `getCurrentCursorPosition().geometry.coordinates`.
2. Use `findWithin` to return an array of site model entities that contain the given coordinate:

```plaintext
// typescript
const point: Vector3 = new api.lib.THREE.Vector3(10, 20, 1);
let floors: SiteModelEntityInterface[] = api.siteModel.repository
  .findWithinGlobal(point, api.siteModel.types.FLOOR);
```

## Getting the Closest Room within Range of a Point

### Procedure

1. Use the MainViewInterface 3D cursor to obtain an arbitrary coordinate by calling `getCurrentCursorPosition().geometry.coordinates`.
2. Use `findClosestByTypeAndDistance2D` to return the site model entity that is nearest to the given coordinate:

```plaintext
// typescript
const point: Vector3 = new api.lib.THREE.Vector3(10, 20, 1);
let room: SiteModelEntityInterface = api.siteModel.repository
  .findClosestByTypeAndDistance2D(api.siteModel.types.ROOM, point, 5);
```

A site model is a three-dimensional model which clusters information by assigning meaningful names to clearly defined areas in the space of a site. With a site model, you can define and name the buildings, floors, rooms, or even more fine-grained spaces, of a site in NavVis IVION. Among other things, this information is used to create the floor changer and enrich POI search.

Site refers to a complex of one or more buildings displayed in a NavVis IVION instance. For example, the Munich Airport would be one site. An instance can contain multiple sites. Each site consists of one or more datasets.
