Layers in OpenLayers 3 are defined with a type (Image, Tile or Vector) which contains a source. The source is the protocol used to get the map tiles. You can consult the list of [available layer sources here](/en/{{ latest }}/apidoc/ol.source.html)
The next part of the `Map` object is the `View`. The view allow to specify the center, resolution, and rotation of the map. Right now, only `View2D` is supported, but other views should be available at some point. The simplest way to define a view is to define a center point and a zoom level. Note that zoom level 0 is zoomed out.

## View
`ol.Map` is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of an `ol.View` instance - typically an `ol.View2D` for 2D maps. The reason for this abstraction is the idea of instantly switching e.g. between a 2D and a tilted 3D view, without the need to maintain two copies of the `layers`.

```js
map.setView(new ol.View2D({

```
An `ol.View2D` also has a `projection`. The projection determines the coordinate system of the `center` and the units for map resolution calculations. If not specified (like in the above snippet), the default projection is Spherical Mercator (EPSG:3857), with meters as map units.

The `zoom` option is a convenient way to specify the map resolution. The available zoom levels are determined by `maxZoom` (default: 28), `zoomFactor` (default: 2) and `maxResolution` (default is calculated in such a way that the projection's validity extent fits in a 256x256 pixel tile). Starting at zoom level 0 with a resolution of `maxResolution` units per pixel, subsequent zoom levels are calculated by dividing the previous zoom level's resolution by `zoomFactor`, until zoom level `maxZoom` is reached.
