OpenLayers

This article or section may contain out-of-date information: Many pages about OpenLayers on this wiki are still based on the OpenLayers version 2 (last release in July 2013). With OpenLayers version 3, the API has changed a lot. For simple maps, Leaflet is an easier and lightweight alternative.
If you know about the current state of affairs, please help keep everyone informed by updating this information. (Discussion)
