| Map | View | Layers |
|---|---|---|
A [map](ol.Map.html) is made of [layers](ol.layer.html), a [view](ol.View.html) to visualize them, [interactions](ol.interaction.html) to modify map content and [controls](ol.control.html) with UI components. [Overview](ol.Map.html)[Creation](ol.Map.html#Map) [Events](ol.MapBrowserEvent.html) |
The view manages the visual parameters of the map view, like resolution or rotation. [ol.View](ol.View.html) with center, projection, resolution and rotation |
Layers are lightweight containers that get their data from [sources](ol.source.html). [ol.layer.Tile](ol.layer.Tile.html)[ol.layer.Image](ol.layer.Image.html) [ol.layer.Vector](ol.layer.Vector.html) |
| Controls | Interactions | Sources and formats |
| [Map default controls](ol.control.html#defaults) [All controls](ol.control.html) |
[Map default interactions](ol.interaction.html#defaults) Interactions for [vector features](ol.Feature.html)

All coordinates and extents need to be provided in view projection (default: [EPSG:3857](ol.proj.EPSG3857.html)). To transform, use [ol.proj.transform()](ol.proj.html#transform) and [ol.extent.applyTransform()](ol.extent.html#applyTransform). [ol.proj](ol.proj.html) |
[Objects](ol.Object.html) can be kept in sync using the [bindTo()](ol.Object.html#bindTo) method. A [DOM Input](ol.dom.Input.html) class is available to bind Object properties to HTML Input elements. |
