# Client Configuration Parameters

This chapter lists the available configuration parameters. You can set them as described in [Client Configuration](/v1/docs/introduction-9). The corresponding menu is the Configuration Editor in the NavVis IVION settings.

## Aliases

Some frequently used parameters have aliases which are shorter and more convenient for use as URL parameters. They are mentioned in brackets, e.g. (or pc).

## Main Settings Parameters

You can view a complete list of the main settings parameters [here](https://ivion-api.docs.navvis.com/latest/reference/interfaces/configurationinterface.html). These parameters can be set from the Configuration Settings, by passing them to an embedded NavVis IVION Instance, by adding them to the NavVis IVION URL, e.g. `http://hostname/iv/?layers.map.visible=false` and via the REST interface (`api/configs`).

## URL-Only Parameters

These parameters can only be set by adding them to the NavVis IVION URL, e.g. `http://hostname/iv/?poi=1&!`. They can, for example, help you set up an alternative startup view.

| Variable | Type | Description |
| --- | --- | --- |
| **Start at a geographic location (set all three of x, y, z)** |
| x | Meters | X-coordinate of the geographic location. A panorama close to this point is chosen as the starting location for the main view. |
| y | Meters | Y-Coordinate of the geographic location |
| z | Meters | Height of the geographic location |
| **Start at a**Point of Interest (POI) |
| poi | Integer or CSV | ID of a POI in the database or `lon`, `lat`, `z` of a custom location. |
| ! | - | Optional. If present, the POI details panel does not open automatically. |
| **Start at a Site Model entity** |
| sme | Integer | ID of the site model entity in the database |
| ! | - | Optional. If present, the site model entity details panel does not open automatically. |
| **Start at an image** |
| image | Integer | ID of the image in the database. Note: The viewing direction can be optionally configured with the `core.init.vlon` and `core.init.vlat` parameters above. |
| **Functionality** |
| lang | String | Overrides the language settings of your browser for NavVis IVION. Possible values: `cs`, `de`, `en`, `es`, `fr`, `ja`, `zh`, `zh_tw`. |
| **Route planning** |
| route.start | Integer or CSV | POI ID or `lon`, `lat`, `z` of a route start point. Route is planned and shown for start and end points. The starting location is the first instruction in the planned route unless the URL includes one of the parameters `image`, `poi`, or `lon`, `lat`, and `z`. |
| route.end | Integer or CSV | POI ID or `lon`, `lat`, `z` of a route end point. |

A NavVis IVION instance is a copy of the NavVis IVION software running on a hosting server. An instance has a database which contains the associated datasets, users, and more. That data is accessible via the instance URL.

A point of interest is a marker placed in NavVis IVION that refers to objects or areas (e.g., cafeteria, coffee machine). POIs can store detailed information about the building features or locations they stand for. POIs appear in NavVis IVION as interactive icons that provide more information when users click on them.

Point Of Interest

The user interface panel which displays the POI description and buttons for sharing, editing, and routing.

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.
