Finding your way round
|
||
----------------------
|
||
See the class list to the right and especially take a look at {@link ol.Map} and {@link ol.layer.Layer} because those are the central objects.
|
||
|
||
In general every use of OpenLayers starts by initializing a map, then adding the required layers. Controls and interactions can be added to change the behavior of the map.
|
||
|
||
Projections
|
||
-----------
|
||
A {@link ol.Projection} defines which point on earth is represented by a pair of coordinates. Coordinates within OpenLayers can be used in various projections where some common projections are always supported, others can be used via Proj4js.
|
||
|
||
Maps and Layers
|
||
---------------
|
||
A map in OpenLayers is essentially a staple of layers that is viewed from the top. Layers are responsible for retieving data and displaying it.
