The Openlayers has been rewritten and the new version is now 3.x. The old branch 2.x is minimally maintained, mostly by contributed patches and/or obvious bugs. The module page is now up to date for 3.x. We are still looking for people to help with code and documentation, feel free to contact us through the issue queue !
Openlayers 3: features & submodules
- A layer is a visual representation of data from a source. OpenLayers supports a wide range of map types and new types can easily be added through the UI or via submodules. See API documentation.
- Openlayers sources belongs to layers and they are representing the layer's data. These are available for free and commercial map tile services like OpenStreetMap or Bing, for OGC sources like WMS or WMTS, and for vector data in formats like GeoJSON or KML. See API documentation.
- Openlayers let you add style to any layers. Styles can be added through the UI or through submodules. Right now we are supporting very basic styles and the UI doesn't exist yet to customize them. See API documentation.
- Projections support lacks in Openlayers 3.x for now but is fully supported on the previous 2.x version.
- Provides user map interactions. See API documentation.
- Provides map controls and widgets. See API documentation.
- This custom object doesn't belong to the Openlayers library, it's just an hybrid component added to the module to let user interact with the map after it has been created.

How to report bugs
- Browse the issue queue to check if the bug hasn't been already reported. There's a great tutorial on how to use it here.
- Use the search function if you don't find anything
- Use the search function again
- Create an issue following the those recommandations
Please, keep in mind that the more work we have in the issue queue, the lesser time we have to work on this module, so, to be clear, before posting an issue, use the search functionality. Fixing bugs is notably more efficient if you provide steps to reproduce the bug.
- Pol Dellaiera: consultant, passionate guy, I love mapping stuff. I need to learn new stuff everyday !
- Peter Philipp: Peter, if you read this, please send me a small introduction paragraph ;-)
- Augustus Kling: PostgreSQL and web GIS developer. Amongst other projects collaboratively develops OpenLayers Editor and the Cartaro distribution.
- 01/06/2015: Openlayers 2.x is no more developped. Patches are still applied if needed. The differences between OL2 and OL3 (lib and module) prevent us to provide an upgrade path, so, expect bugs if you upgrade from OL2 to OL3.
- 14/01/2015: OpenLayers 7.x-3.x is now in development, please use it, test it, give feedback and if you want, contribute. See this page for a more complete roadmap.
Upgrading steps for 3.x
Openlayers 3.x is under heavy development. A lot of things has changed internally in between each beta versions. We are still trying to find an optimal way to organize classes so the module is easily extendable by everyone.
Anyhow, when upgrading from a version to another, here are the steps with drush once the new code has been installed:
- drush rr (from Registry Rebuild)
- drush cc all
- drush updb
