Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
For additional documentation, tutorials, links to presentation and upgrade information check OpenLayers 2.x Documentation for D6.
Note — D6 documentation is fairly correct except for the OpenLayers WKT field which is not present in D7. (Geofield is recommended however it has a number of critical issues.)
