OpenLayers is an open source Javascript web mapping library for creating web map applications.

OpenLayers is a JavaScript library which implements an API for developing dynamic map widgets on the web. The library provides tools for presenting and editing geographic information using pure JavaScript with no server-side dependencies.

OpenLayers supports several different access methods for geographic data, including the OpenGIS Web Mapping Service (WMS) and Web Feature Service (WFS) protocols from the Open Geospatial Consortium. Other supported geographic data sources include OpenStreetMap, Bing Maps, and ArcGIS Server. See the OpenLayers live examples page or the documentation for more comprehensive details.

OpenLayers is a project of the Open Source Geospatial Foundation (OSGeo) and is released under a BSD-style license (also known as the BSD-2-clause).
