Please also note the installation of the Openlayers sub-modules may require one or more of the following modules to be installed:

• Geofield

Openlayers module

Download the Drupal Openlayers module, and install the Openlayers module and the Openlayers UI sub-module.

Openlayers library

Download and extract the Openlayers javascript library from http://openlayers.org/download/.  You can choose to download the vX.Y.Z.zip version or the vX.Y.Z-dist.zip version - both will work under 7.x-3.2 of the module.

For version 7.x-3.1, copy the extracted folder into your sites "libraries" folder into a sub-folder named "openlayers3".  The main ol.js file should then be available at "sites/all/libraries/openlayers3/build/ol.js".

For version 7.x-3.2 onwards, it is now possible to hold multiple local versions of the Openlayers library, so copy the extracted folder into your site "libraries" folder into a sub-folder named "openlayers3/versions/vX.Y.Z", where vX.Y.Z is the version number of the downloaded library.  The main ol.js file should then be available at "sites/all/libraries/openlayers3/versions/vX.Y.Z/build/ol.js" (when using the vX.Y.Z.zip version) or "sites/all/libraries/openlayers3/versions/vX.Y.Z/ol.js" (when using the vX.Y.Z-dist.zip version).
