# Layer

The web app supports several types of layers:

* GeoJSON
* Mapbox Vector Tiles
* Cluster
* Surface

Available layers can be toggled active. Each layer has zoom levels set where layer becomes visible or hidden. It also supports different data sources for different zoom levels to allow cartographic generalisation.
