OpenLayers is a popular open source JavaScript library for displaying dynamic map data in a web page. The OpenLayers library can work as the client half of an AJAX map application, including modern features such as "slippy" maps. Most if not all of the map data is provided by servers running other software.
OpenLayers supports a wide range of different map sources, making it a popular way to combine a wide range of different data types into one map.
The OpenLayers package, documentation, and examples be found at the official OpenLayers site. OpenLayers was originally created by MetaCarta, but in November 2007 it became a project of the Open Source Geospatial Foundation. It is distributed under a modified BSD license.
As the name suggests, the real strength of OpenLayers is its capability of creating a map from a range of different data layers of differing types. Supported data sources include:
- Web Map Service (WMS)
- Web Feature Service (WFS)
- Web Map Coverage (WMC)
- OpenStreetMap
- Virtual Earth
- Yahoo! Maps
- MapServer
- MapGuide Open Source
- GeoServer
- ka-Map
- World Wind Servers
- GeoRSS
- KML
- GML
- GPX
- SLD
- GeoJSON
- Well Known Text (WKT)
- Client JavaScript annotation
Documentation mainly takes the form of class descriptions. However, the OpenLayers site has an extensive list of examples that can be cribbed from. These will get you working, give you a good idea of capabilities, and also demonstrate how particular features are used. In common with most if not all popular open source projects, the site hosts an active and helpful user community. [...]
