Display and browse through building floors from a floor-aware web map.
Use case
Having map data to aid indoor navigation in buildings with multiple floors such as airports, museums, or offices can be incredibly useful. For example, you may wish to browse through all available floor maps for an office in order to find the location of an upcoming meeting in advance.
How to use the sample
Use the spinner to browse different floor levels in the facility. Only the selected floor will be displayed.
How it works
- Create a
PortalItem
using theitemId
of the floor-aware web map. - Set the
MapView
to display thePortalItem
. - Wait for the map to load and retrieve the map's floor manager from
MapView.Map.FloorManager
. Then runFloorManager.loadAsync()
. - Wait for the floor manager to load using
FloorManager.addDoneLoadingListener
to retrieve the floor-aware data. - Set all floors to not visible
FloorManager.levels[floor-number].isVisible = false
. - Set only the selected floor to visible using
FloorManager.levels[floor-number].isVisible = true
.
- Note: Manually set the default floor level to the first floor.
Relevant API
- FloorManager
About the data
This sample uses a floor-aware web map that displays the floors of Building L on the Esri Redlands campus.
Additional information
The API also supports browsing different sites and facilities in addition to building floors.
