Mappedin MapLibre Overlay

Mappedin SDK version 6 is currently in a beta state while Mappedin perfects new features and APIs. Open the v6 release notes to view the latest changes.

Using Mappedin Web SDK with your own map requires a Pro license. Try a demo map for free or refer to the Pricing page for more information.

Mappedin Web SDK makes use of MapLibre to render the outdoor portion of the map. The SDK exposes this layer through MapView.OutoorMap and can be used to add additional layers as described in the Outdoor Map Guide.

It is also possible to utilze the opposite architecture, by adding a MapView to a MapLibre Map. This is accomplished by using the MappedinMapLibreOverlay class. It allows a developer to easily add a Mappedin indoor map to an existing MapLibre based app.

Example

The following example demonstrates the use of MappedinMapLibreOverlay. A MapLibre Map is created, using the indoor map's center point as it's initial position. Once the MapLibre map is loaded, a MappedinMapLibreOverlay is added using the MapLibre addControl method.

When the map is clicked, the current MappedinMapLibreOverlay is removed and a new one added to show an indoor map of a different building. The map is then moved to the center point of the new indoor map.
