OpenLayers 3| Map | View | Layers |
|---|---|---|
A map is made of layers, a view to visualize them, interactions to modify map content and controls with UI components. OverviewCreation Events |
The view manages the visual parameters of the map view, like resolution or rotation. ol.View with center, projection, resolution and rotation |
Layers are lightweight containers that get their data from sources. ol.layer.Tileol.layer.Image ol.layer.Vector |
| Controls | Interactions | Sources and formats |
| Map default controls All controls |
Map default interactions Interactions for vector features All interactions |
Tile sources for ol.layer.Tile
Image sources for ol.layer.Image Vector sources for ol.layer.Vector Formats for reading/writing vector data ol.format.WMSCapabilities |
| Projections | Observable objects | Other components |
All coordinates and extents need to be provided in view projection (default: EPSG:3857). To transform, use ol.proj.transform() and ol.proj.transformExtent(). ol.proj |
Changes to all ol.Objects can observed by calling the object.on('propertychange') method. Listeners receive an ol.ObjectEvent with information on the changed property and old value. | ol.DeviceOrientation ol.Geolocation ol.Overlay ol.FeatureOverlay |
