About OpenLayers
OpenLayers is a JavaScript library for displaying maps in your browser. Highly extensible, it serves as the foundation of all of our web mapping interfaces. OpenLayers accesses data through industry standards, leaving it free of server-side dependencies. It is released under a BSD-style license.
- Overlay multiple standards-compliant map layers into a single application
- Displays tiles/images from WMS, WMTS, TMS, WMS-C, WMTS, Google Maps, Bing Maps, Yahoo Maps, OpenStreetMap, ArcGIS Server, ArcIMS
- Vector feature rendering and styling with support for KML, GeoJSON, WKT, GML, WFS, GeoRSS
- Web-based editing, including feature snapping and splitting, via WFS-Transactional (WFS-T) leveraging SVG or VML
- Pluggable with any JavaScript toolkit (JQuery, Ext, Dojo, MooTools)
- Client side map reprojection
- Feature clustering and paging
OpenLayers Applications
OpenLayers provides a powerful foundation for web mapping applications like the ones below:
- Styler: An interactive styling application for geospatial data.
- Community Almanac: A collaborative community building and story telling application developed for the Orton Foundation.
- GeoView: A tool for browsing geospatial data on the web.
- Vespucci: A collaborative mapping tool that takes advantage of GeoServer's versioning capability.
- NYC Building Editor: A simple demo of GeoServer's versioning ability.

Recent Contributions
OpenGeo funds ongoing development of OpenLayers as part of our larger mission to make public geodata more accessible and usable to civil society. Recent contributions include:
- Major improvements to vector rendering and especially the VML renderer.
- Adding point symbol rotation, support for well known symbols and dashed/dotted lines and borders to the SLD support.
Core Development Roadmap
Creating new geometry from COGO directions is a common use case for web editing tools in county and municipal jurisdictions. This work item will take in COGO directions and return a feature suitable for rendering on the map, sending back to the server, etc.
Support Cascadenik, a way to style maps in using a syntax similar to CSS, as a way to persist and create OpenLayers style objects. Makes cartography easy for web designers.
CQL is a terse language for writing data filters. This item will allow users to flip between a GUI view of the filter and a text view of the filter in CQL, and edit either one.
